History VideoGame / AnotherMetroid2Remake

** The Geneses in ''VideoGame/MetroidFusion'' were standard enemies that were restricted to crawling around in ceiling ducts and dropping acidic saliva on you. In this game, just one Genesis has a lot more room to move around, can do a lot more damage, and serves as the game's BonusBoss.

* BonusBoss: Genesis, boss of the GFS Thoth, which is completely optional to find and only holds expansion pickups. Furthermore, unlike other somewhat optional bosses that guard maneuverability or beam upgrades, the only thing you gain from beating it is a single Energy Tank.

* InterfaceScrew: Throughout the distribution center are explodable spheres and energy fields that effectively act as [=EMPs=], causing static on the screen and disabling Samus's weapons if triggered.[[note]]The Screw Attack still works, though, and the Gravity Suit renders you immune.[[/note]]

** In the original game, Samus can only hold one beam weapon at a time. Therefore, while they were first offered in previous areas, each beam type could also be collected from a second[[note]]or third, in the Ice Beam's case[[/note]] Chozo statue found later in the game so that Samus would not have to backtrack as much if she needed to switch beam types. In ''Another Metroid 2 Remake'', beam weapons are permanently held once collected, so therefore each beam is only offered by a single Chozo statue in the game.

* AntiClimax: The scripted event where [[spoiler:the Queen Metroid starts biting down on Samus]] can be resolved with [[spoiler:dropping a Power Bomb in her stomach and having her explode in a shining burst of light, her bloody carcass dripping around you as it rests on the ground]]... ''or'' you can just hit her with a few more missiles/super missiles/regular bombs/power bombs [[spoiler:in her mouth]] and watch something that's about as climactic as [[spoiler:any other Metroid death]], possibly less so.

** After the chamber that upgrades Samus' suit to the Gravity Suit opens, the shadows plus her blue TronLines makes her briefly look like Dark Samus.

** You can also find the same room Samus got infected by the X-Parasites in at the beginning of ''VideoGame/MetroidFusion''. There's even the same enemy placed there, albeit it's obviously ''not'' infected -- yet.
** On the GFS Thoth you find a trio of creatures from ''Metroid Fusion'' stored inside capsules: B.O.X.'s brain, an Evir, and a piece of Nightmare. Hiding near them as a boss is another enemy from that game, the Genesis. The Save station there also is of a design similar to the Navigation/Recharge rooms from ''Fusion''.

* DoorToBefore: Inside the Distribution Center area lie four tubes that effectively act as a WarpZone, enabling quick travel across much of the game world to areas already discovered.

* FiveSecondForeshadowing: At the bottom of the Hydro Station Breeding Grounds is an Alpha Metroid partway evolved the next phase of Metroid evolution. On the way back out of that room is a surprise encounter with a Gamma Metroid.

** Acquiring the newly added charge beam in the demo. When you encounter it, it's blocked up by a different colored block. ''Nothing'' you can do can break it, so in grand Metroid tradition you think you're supposed to come back with a weapon that ''can'' break it. [[spoiler:Nope! Absolutely ''none'' of your upgrades can break it. Instead, you're supposed to shoot the orbs hanging from the ceiling not far off in order to move it. Not only is there ''any'' indication you're supposed to do that or that the two are related, unless you start shooting around at random and accidentally hit one, said orbs also blend way too well into the background, which would make one believe they ''are'' nothing but background]]. In the full release, the steps above net you an Energy Tank, while the Charge Beam can be found where the Ice Beam was in the original.

* InterfaceScrew: Throughout the distribution center are spheres and areas that effectively act as [=EMPs=], causing static on the screen and disabling Samus's weapons if triggered.[[note]]The Screw Attack still works, though, and the Gravity Suit renders you immune.[[/note]]

* LateToTheParty: In a change from the source material, Samus is not just on [=SR388=] to eradicate the Metroids, but also to find the whereabouts of the Federation science team of the GFS Thoth, and the Search-and-Rescue team that got sent after them.

* MagicCountdown: A variation of this plays out in the Power Bomb Escape sequence. If you are doing poorly, the unstable reactor's temperature will climb slower until you reach unmarked progress points. If you are able to speed through the obstacles and fights in your path, the temperature will seem to 'spike' as you cross those progress points. No matter your performance, [[spoiler:you will always be held up by the slowly-operating blast doors at the very end so that [[FailureIsTheOnlyOption you get caught in the blast]]]].

* MilitariesAreUseless: Surprisingly averted with the Search and Rescue marines. Not only did they make it quite far into [=SR388=], but when you finally catch up they're busy actually ''gaining the upper hand against a Zeta Metroid''. Unfortunately it picks that moment to metamorphose into an Omega Metroid, which even ''Samus'' will struggle to defeat, and soundly slaughters the marines.

** Thought you could mix and match strategies and use the Power Bombs to instagib the Queen Metroid like in ''VideoGame/MetroidOtherM''? Hope you like pain with your futility! [[spoiler:There's a scripted event where the Queen bites down after Samus has no more room to run, and ''that'' is when you re-enact its death in ''Other M''.]]

* PowerupLetdown: The Ice Beam. You get it as the ''last'' weapon in the game, at a point when your beam has been upgraded enough to make quick work of most enemies. The way it freezes enemies makes it much more tedious to farm powerups[[note]]A frozen enemy can't be shot again to destroy it. Instead, you need to follow its frozen body as it falls to the ground or wait for it to shatter[[/note]], leading many players to turn it off unless actually needed. Despite being rendered obsolete by the Space Jump, many fans also miss the staple ability to use frozen enemies as platforms.

* ShieldedCoreBoss: The Tester has two layers of shields protecting its vulnerable core: four segments of armor plating that are immune to beams but vulnerable to missiles, and an energy shield that is immune to missiles but vulnerable to beams. Each segment of armor will eventually repair itself if not destroyed completely, but the inner energy shield is gone for good once you break it (unless you're playing on hard mode, in which case it will also regenerate over time).

* TheStinger: The 1.4 fan patch adds a second stinger if you collected all the pickups: [[spoiler:The crystals the Baby Metroid were feeding on were actually [[VideoGame/MetroidFusion crystallized X Parasites]], which now are able to revitalize and roam free on [=SR388=], as Samus exterminated their predators.]]

** Thought you could mix and match strategies and use the Power Bombs to instagib the Queen Metroid like in ''[[VideoGame/MetroidOtherM''? Hope you like pain with your futility! [[spoiler:There's a scripted event where the Queen bites down after Samus has no more room to run, and ''that'' is when you re-enact its death in ''Other M'']].

* PowerupLetdown: The Ice Beam. You get it as the ''last'' weapon in the game, at a point when your beam has been upgraded enough to make quick work of most enemies. The way it freezes enemies makes it much more tedious to farm powerups[[note]]A frozen enemy can't be shot again to destroy it.

Despite being rendered obsolete by the Space Jump, many fans also miss the staple ability to use frozen enemies as platforms.

* StupidityIsTheOnlyOption: The room with the Power Bombs requires Samus to use them and damage a power cell in order to exit, leading to her having to run and escape Power Plant in order to not get caught in the cell's meltdown.

** [[spoiler:Torizo, the animated Chozo Statue that holds the Space Jump]]. It's got plenty of health and moves ''really'' fast when it's low on health. [[spoiler:And it has two phases, with no chance to refill your health in-between]].

* AsymmetricMultiplayer: The Multitroid version of the game also includes a "SA-X" mode with two teams - one team uses Fusion suits and only start with ice missiles, and the other team are SA-X enemies with a full set of equipment. The Fusion players have to complete the game as normal, while the SA-X players [[CompetitiveMultiplayer have to kill all the Fusion players before they can do so]]. The latter is trickier than it sounds, since locating the Fusion players on such a big map is enough of a challenge to begin with. The SA-X players start with a significant advantage in terms of combat capability, but the Fusion players gradually become more capable of fighting back as they acquire upgrades -- on the other hand, the SA-X players will respawn back at their starting point when killed, whereas the Fusion players only have one life each.

* TheStinger: The 1.4 fan patch adds a second stinger if you collected all the pickups: [[spoiler:The crystals the Baby Metroid were feeding on were actually [[VideoGame/MetroidFusion crystalized X Parasites]], which now are able to revitalize and roam free on [=SR388=], as Samus exterminated their predators.]]

** In the original ''Metroid II'', Samus's mission was just to exterminate all of the Metroids. In this version she also has the secondary mission of finding the Research and Rescue Teams sent by the Galactic Federation, [[AllThereInTheManual which were mentioned in ''Metroid II'''s instruction manual but did not appear anywhere in the actual game]]. [[spoiler:She fails to save the Research Team, and is just barely too late to save the Rescue Team]].
* AdaptedOut: The Septoggs and Blob Throwers do not appear in this remake. Averted since they eventually appeared in later updates.

** The scattered energy/missile rechargers from the original are now part of the more easily-found Save Stations, making it much easier to replenish missiles (as well as scrapping the possible need to [[ItemFarming farm]] upon loading up a saved game).

* BodyHorror: The first time you see an Alpha molt from a regular Metroid, it's much like the original: the molted skin bursts and out comes the Alpha. But when you meet your first Gamma, it shows up as a regular Alpha... then its eyes close, its plated armor segments and its legs and fangs elongate amid spurts of gray blood, showing that the [[PainfulTransformation transformation is far from painless]], and its now-triplicated eyes open and it screeches.

* BossArenaUrgency: At the Tower, one Gamma Metroid is fought in a cavern full of sand. The sand covers a deadly bed of spikes along the cavern floor. Unfortunately, the Gamma Metroid's electrical attack clears away any sand that it touches. The longer the fight continues, the less safe ground Samus has to stand on.

** You can find the landing site and base of Galactic Federation Troopers in this game. In a similar manner to ''VideoGame/MetroidPrime2Echoes'', it's not a pretty sight... Thankfully, though, there's no zombie troopers to deal with.

** On the GFS Thoth you find a trio of creatures from ''Metroid Fusion'' stored inside capsules: B.O.X.'s brain, Evir and a piece of Nightmare. Hiding near them as a boss is another enemy from that game, the Genesis. The Save station there also is of a design close to the Navigation/Recharge rooms from ''Fusion''.

** Thought you could mix and match strategies and use the Power Bombs to instagib the Queen Metroid? Hope you like pain with your futility! [[spoiler:There's a scripted event where the Queen bites down after Samus has no more room to run, and ''that'' is when you re-enact its death in ''Other M'']].

* ShieldedCoreBoss: The Tester has two layers of shields protecting its vulnerable core: four segments of armor plating that are immune to beams but vulnerable to missiles, and an energy shield that is immune to missiles but vulnerable to beams. Each segment of armor will eventually repair itself if not destroyed completely, but the inner energy shield is gone for good once you break it (unless you're playing on hard mode, in which case it will also regenerate).

* ApocalypticLog: Fan patch 1.4 adds these in form of dead Federation Marines you get to scan. One of them in particular gets quite obsessed in hunting down the Metroid that killed his partner.

* JumpScare: The 1.4 fan patch adds a new one, giving players in higher difficulties an extra surprise: [[spoiler:''more Metroid larvae to fight at the Genetics Laboratory''. Gets particularly bad in the last room where you encounter them]].

* TheStinger: The 1.4 fan patch adds another if you collected all pickups: [[spoiler:The crystals the Baby Metroid were feeding on were actually [[VideoGame/MetroidFusion crystalized X-Parasites]], which now are able to revitalize and roam free on [=SR388=], as Samus exterminated their predators.]]

* FissionMailed: The game is scripted so that it is [[FailureIsTheOnlyOption impossible]] to escape the blast radius of the exploding power cell underneath the Tower. Players may notice the power cell's temperature increase at a much faster rate once they reach the two blast doors, and it will always detonate just as the second door opens. After an explosion that fills the whole screen, they are treated to the image of Samus lying on the floor amidst the rubble as her energy drops quickly... but then unexpectedly stops at five, and she gets back up. [[spoiler:Going back towards the ruined power cell chamber leads players to a free Energy Tank and Missile Tank, fully replenishing Samus's health and then some.]]

** Acquiring the newly added charge beam in the demo. When you encounter it, it's blocked up by a different colored block. ''Nothing'' you can do can break it, so in grand Metroid tradition you think you're suppose to come back with a weapon that ''can'' break it. [[spoiler:Nope! Absolutely ''none'' of your upgrades can break it. Instead, you're suppose to shoot the orbs hanging from the ceiling not far off in order to move it. Not only is there ''any'' indication you're suppose to do that or that the two are related, unless you start shooting around at random and accidentally hit one, said orbs also blend way too well into the background, which would make one believe they ''are'' nothing but background]]. In the full release, the steps above net you an Energy Tank, while the Charge Beam can be found where the Ice Beam was in the original.

* AdaptedOut: The Septoggs and Blob Throwers do not appear in this remake.

* DualBoss: When Samus [[spoiler:finds the dead research team,]] she must fight two Alpha Metroids at the same time. Taken UpToEleven later in the Distribution Center, when she must fight [[spoiler:'''five''']] Alpha Metroids at once. There's also a point in the same area where she must fight two Gamma Metroids at once.

** Numerous areas have been given complete artistic overhauls[[note]]Not that the original gave Guasti much to work with, since the [=GameBoy=]'s graphical limitations restricted things to gray on a black background[[/note]], entire enemies and even ''bosses'' have been added from scratch, and items and powers featured later in the ''Franchise/{{Metroid}}'' series have been added as well.[[note]]Such as the Super Missile, Speed Boost, Charge Beam, and Power Bomb.[[/note]]

* LateToTheParty: In a change from the source material, Samus is not just on [=SR388=] to eradicate the Metroids, but also to find the whereabouts of the Federation science team of the GFS Thoth, and the Search-And-Rescue team that got sent after them.

* {{Metroidvania}}: [[VideoGame/MetroidIIReturnOfSamus The original game]] is looked down upon by Metroid fans today for being one of the few games with a lesser Metroidvania influence. Taking this criticism to heart, [=DoctorM64=] and the rest of the team have gone and added more elements that are common in the genre, such as optional side areas, secret passages between areas, and sections of the map that require late game items to reach.
* MilitariesAreUseless: Surprisingly averted with the Search and Rescue marines. Not only did they make it quite far into SR-388, but when you finally catch up they're busy actually ''gaining the upper hand against a Zeta Metroid''. Unfortunately it picks that moment to metamorphose into an Omega Metroid, which even ''Samus'' will struggle to defeat, and soundly slaughters the marines.

** Arachnus is also tougher than in ''Metroid II'', and even its appearance in ''VideoGame/MetroidFusion'', now being faster and able to take a lot more hits.
** The Geneses in ''VideoGame/MetroidFusion'' were standard enemies that were restricted to ducts and dropping acidic saliva on you. In this game, just one Genesis has a lot more room to move around, can do a lot more damage and serves as the game's BonusBoss.

** While in the original Samus's mission was just to exterminate all of the Metroids, in this version she also has the secondary mission of finding the Research and Rescue Teams sent by the Galactic Federation. [[AllThereInTheManual These were mentioned in the manual to the original game, but did not appear anywhere in the actual game]]. [[spoiler:She fails to save the Research Team, and is just barely too late to save the Rescue Team]].

* ArtifactTitle: Zig-zagged. The project got started in 2006, when interest in ''Metroid II'' fan remakes was extremely high due to the very successful ''VideoGame/MetroidZeroMission'', a remake of the first game, and there were plenty of efforts to make a fan remake of the second game in the same vein. As the years went by, every one of these projects ended up dying or disappearing, and ''[=AM2R=]'' simply turned out to be the last man standing. However, shortly after release it was DMCA'd because Nintendo had an actual remake in the works, so now the title fits again because it literally is another ''Metroid II'' remake.
* BodyHorror: The first time you see an Alpha molt from a regular Metroid, it's much like the original. The molted skin bursts and out comes the Alpha. But when you meet your first Gamma, it shows up as a regular Alpha. Its eyes close, its plated armor segments and its legs and fangs elongate amid spurts of gray blood, showing that the [[PainfulTransformation transformation is far from painless]], and then its now-triplicated eyes open and it screeches.
* BonusBoss: Genesis, boss of the GFS Thoth, which is completely optional to find and only holds expansion pickups. Furthermore, unlike other somewhat optional bosses that guard maneuverability or beam upgrades, the only thing to gain from beating it is a single Energy Tank.

** After the chamber that upgrades Samus' suit to the Gravity Suit, the shadows plus her blue TronLines makes her briefly look like Dark Samus.

** You can also find the same room Samus got infected by the X-Parasites in at the beginning of ''VideoGame/MetroidFusion''. There's even the same enemy placed there, albeit it's obviously ''not'' infected - yet.

** Serris, a boss fought on the research station in ''Metroid Fusion'', makes an appearance, and it's tougher than the parasite-emulated one.

* CurbStompBattle: When [[spoiler:a newly grown Omega Metroid faces the last Galactic Federation troopers]], it kills them in the time it takes Samus to cross the room.

** [=TPOs=] and Meboids, two examples of the very common "fly back and forth horizontally" enemy type from the original game, now each have unique behaviors. [=TPOs=] will split in two when attacked and aggressively hone in on Samus. Meboids spawn infinitely from clusters that they swarm around to protect, and can only be effectively defeated with an Ice Beam and missile combo.

* FissionMailed: The game is scripted so that it is [[FailureIsTheOnlyOption impossible]] to escape the blast radius of the exploding power cell underneath the Tower. Players may notice the power cell's temperature increase at a much faster rate once they reach the two blast doors, and it will always detonate just before the second door opens. After an explosion that fills the whole screen, they are treated to the image of Samus lying on the floor amidst the rubble as her energy drops quickly... but then unexpectedly stops at five, and she gets back up. [[spoiler:Going back towards the ruined power cell chamber leads players to a free Energy Tank and Missile Tank, fully replenishing Samus's health and then some]].

** If you're one of the unlucky ones to have a certain graphics card, Samus would turn invisible when you equip the Gravity Suit. While it's not ''entirely'' breaking as you could use the Varia Suit instead, it makes navigating the underwater areas needlessly more difficult and turns Serris into a much more difficult fight.

** Acquiring the newly added charge beam in the demo. When you encounter it, it's blocked up by a different colored block. ''Nothing'' you can do can break it, so in grand Metroid tradition you think you're suppose to come back with a weapon that ''can'' break it. [[spoiler:Nope!

Not only is there ''any'' indication you're suppose to do that or that the two are related, unless you start shooting around at wild and accidentally hit one, said orbs also blend way too well into the background, which would make one believe it ''is'' nothing but background]]. In the full release, the steps above net you an Energy Tank, while the Charge Beam can be found where the Ice Beam was in the original.

* HarmlessFreezing: Largely averted, which is surprising since most ''Franchise/{{Metroid}}'' games play it straight. Frozen enemies are affected by gravity and will eventually [[LiterallyShatteredLives shatter]] (you can speed up the process with a missile). Played straight with the Larva Metroids in the last area, which must be frozen then shattered with missiles as per other games in the series.
* HeartbeatSoundtrack: The remixed theme for [[https://www.youtube.com/watch?v=HCbXCrMChN0 The Nest]], which features a steady, heartbeat-like rhythm.

* InterfaceScrew: Throughout the distribution center are spheres and areas that effectively act as [=EMPs=], causing static on the screen and disabling all weapons if triggered.[[note]]The Screw Attack still works, though, and the Gravity Suit renders you immune.[[/note]]

* {{Knockback}}: Features all three kinds! Getting hit makes Samus flinch (which also cancels her charge beam if you were charging up) and knocks her back a bit. Strong enemies like Zeta and Omega Metroids are capable of not only causing knockback, they can also cause knockdown to make Samus stunned for a moment.

* LoneWolfBoss: Unless one counts the numerous evolutionary forms of Metroids as bosses, none of the game's bosses, save for the [[FinalBoss Queen Metroid]], have any ties to the Metroids and are all just acting of their own programming or accord.
* MagicCountdown: A variation of this plays out in the Power Bomb Escape sequence - If you are doing poorly, the unstable reactor's temperature will climb slower until you reach unmarked progress points. If you are able to speed through the obstacles and fights in your path, the temperature will seem to 'spike' as you cross those progress points. No matter your performance, [[spoiler:you will always be held up by the slowly-operating blast doors at the very end so that [[FailureIsTheOnlyOption you get caught in the blast]]]].

* {{Nerf}}: Omega Metroids were considered to be ThatOneBoss by many due to how hard they hit and how they could eat up a lot of missiles, especially if you lacked super missiles or wasted them. Patch 1.1 reduced their health and damage output.

** Oh, you thought you were just gonna walk out with the Space Jump, like in the original game? Think again. [[spoiler:The Chozo statue awakens and reveals itself to be Torizo.]]

* ParryingBullets: Both Zeta and Gamma Metroids will gladly swat away every other missile you shoot at them.

* StupidityIsTheOnlyOption: The room with the Power Bombs requires Samus to use them and destroy a power cell in order to exit, leading to her having to run and escape the tower in order to not get caught in the cell's meltdown.

* ApocalypticLog: Fan patch 1.4 adds those in form of dead Federation Marines you get to scan. One of them in particular gets quite obsessed in "[[MadnessMantra getting himself some fun]]" after a Metroid killed his partner.
* AsymmetricMultiplayer: The Multitroid version of the game also includes a "SA-X" mode with two teams - one team use Fusion suits and only start with ice missiles, and the other team are SA-X enemies with a full set of equipment [[CompetitiveMultiplayer who are hunting them down.]] The Fusion players have to complete the game as normal, while the SA-X players have to kill all the Fusion players before they can do so. The latter is trickier than it sounds, since locating the Fusion players on such a big map is enough of a challenge to begin with, but the SA-X players start with a significant advantage in terms of capabilities, though the Fusion players gradually become more capable of fighting back as they acquire upgrades, but the SA-X players will respawn back at their starting point when killed, whereas the Fusion players only have one life each.
* CallBack: One of the logs added in the 1.4 fan patch show the different forms of Metroid seen at the course of the ''VideoGame/MetroidPrime'' games, while explaining why the ones at [=SR388=] are so unique.
* DidntSeeThatComing: The research team were prepared with many ways to freeze Metroids and have their back up blast them to pieces. But when it turned out that the Metroids could grow into a freeze proof form that can only be taken out by [[MoreDakka excess missiles]], they were caught completely off guard and were mostly helpless.

* JumpScare: The 1.4 fan patch adds a new one, giving players in higher difficulties an extra surprise: [[spoiler:''more Metroid larvae to fight at the Genetics Laboratory''. Gets particularly bad at the last room where you encounter them]].

** Added in the 1.2 fan patch. The lava starts off at the level just below the Distribution Center, allowing you to explore everything up to that point in whatever order you want, though you do have to defeat all the Metroids in those areas before you can go any further.
** There's also a Random Game+ mode, which is like New Game+, but it shuffles the locations of all the major upgrades (for example, you might get the High Jump Boots as early as the Golden Temple, but have to wait until the Tower to get the Charge Beam). Some minor modifications are made to the levels so [[UnintentionallyUnwinnable you can't get trapped without a way to progress]]. There are also options that allow you to shuffle the regular item expansions or to shuffle the item expansions ''with'' the major upgrades.

* AsymmetricMultiplayer / CompetitiveMultiplayer: The Multitroid version of the game also includes a "SA-X" mode with two teams - one team use Fusion suits and only start with ice missiles, and the other team are SA-X enemies with a full set of equipment who are hunting them down. The Fusion players have to complete the game as normal, while the SA-X players have to kill all the Fusion players before they can do so.

** In the final area of the game, if you froze a Metroid and it went off-screen, it was possible for it to [[PermanentlyMissableContent despawn]], making the game UnwinnableByMistake. Because the doors lock during Metroid battles, you couldn't simply exit and reenter the room to try to respawn the Metroid, and you were trapped in the room permanently, forcing a restart from your last save point.

** Serris, a boss fought on the research station in ''Metroid Fusion'', makes an appearance, this time in its natural habitat, and it's tougher than the parasite-emulated one.
** Clearing the game quickly enough[[note]]In under two hours[[/note]] gets you a scene featuring Samus contacting [[VideoGame/SuperMetroid Ceres Space Colony]].

* FiveSecondForeshadowing: At the bottom of the Hydro Station Breeding Grounds is an Alpha Metroid partway evolved the next phase of Metroid Evolution. On the way back out of that room is a surprise encounter with a Gamma Metroid.

** If you're one of the unlucky ones to have a certain graphics card, Samus will turn invisible when you equip the Gravity Suit. While it's not ''entirely'' breaking as you can use the Varia Suit instead, it makes navigating the underwater areas needlessly more difficult and turns Serris into a much more difficult fight.

Because the doors lock during Metroid battles, you can't simply exit and reenter the room to try to respawn the Metroid, and you are trapped in the room permanently.

The project got started in 2006: at the time, interest in ''Metroid II'' fan remakes was extremely high due to the very successful ''VideoGame/MetroidZeroMission'', a remake of the first game, and there were plenty of efforts to make a fan remake of the second game in the same vein. As the years went by, every one of these projects ended up dying or disappearing, and ''[=AM2R=]'' simply turned out to be the last man standing.

The game was officially released the August 6th 2016, for the 30th anniversary of ''Metroid''. Due to [[ScrewedByTheLawyers DMCA takedowns]], apparently sent on Nintendo's behalf, you can no longer download it from the [[http://metroid2remake.blogspot.com/ developer's blog]]. Guasti said at first he and the rest of the development team would continue to update and improve the game, but due to a DMCA notice sent by Nintendo directly a week after the first DMCA notice (which apparently wasn't from an official Nintendo source), any future updates that were planned are now squashed. He has also requested fans to not hate on Creator/{{Nintendo}} for the DMCA takedowns, as it is their legal obligation to protect their IP. He has also suggested people buy the original ''Metroid II'' off the eShop to show them that people are still interested in the 2D {{Metroidvania}} genre.

Of course, given that the game had already been released, this was guaranteed to cause StreisandEffect and ensured that fans [[KeepCirculatingTheTapes would put up their own downloads]]. Furthermore, some dedicated fans have since managed to reverse engineer the game's source code, and have as a result been able to release a couple of unofficial patches, fixing most, if not all, of the remaining bugs and even implemented most of the original team's planned, but unfinished features.

''Another Metroid 2 Remake'' (aka Project [=AM2R=]) is a FanRemake of the 1991 UsefulNotes/GameBoy game ''VideoGame/MetroidIIReturnOfSamus'', started and headed by the programmer Milton "[=DoctorM64=]" Guasti. The project, which started development around 2006, aims to update the gameplay and graphics of the original game in the vein of ''VideoGame/MetroidZeroMission'', and while beginning as a hobby project by Guasti, it expanded over time to include several different contributors from around the globe.

* AdaptedOut: The Septoggs and Blob Throwers do not appear in this remake.
