History Main / HundredPercentCompletion

* ''VideoGame/{{BARK}}'': There are five doggy treats in each level to eat. See if you're able to find them all.

* ''VideoGame/{{Metroid}}'':

* ''VideoGame/EtrianOdyssey'': The player's Guild Card in each game keeps track on the achievements you meet through your adventure (they're retained in the NewGamePlus). Some of them will come to you with normal progress (complete a certain stratum, for example), but for others you have to collect all treasures from chests or defeat all bosses on the highest difficulty level available, for example (which is easier said than done, due to the series' NintendoHard nature).

** The ending of ''VideoGame/WarioLandSuperMarioLand3'' is determined by how many coins and treasures Wario has picked up during the game—specifically, this determines how big a castle he can buy. Finishing with 99999 coins ''and'' all the treasures results in getting [[spoiler:the entire ''moon''.]]

** In ''VideoGame/KingdomHeartsI'', you have to lock all the worlds, rescue all the Dalmatians, and beat the Hades Cup to get an extra bonus movie after the credits. A later release of the game requires you to do all the Trinities and beat Kurt Ziza as well, but gives you a longer movie. ''Final Mix'' ups the ante some: to get the extra long secret movie, you have to rescue all 101 Dalmations, find every Trinity mark, play every minigame at least once, and beat every single enemy in the game, which includes the {{Superbosses}}. Unless you play on Proud Mode, in which case you merely have to lock all worlds and beat the Hades Cup.

* ''VideoGame/{{Unpacking}}: The game has 27 stickers you can collect by completing hidden achievements.

** The novel keeps track off the (numbered) bad ends with tiger stamps. Collecting all the stamps and completing all the endings nets the player a short video and a new title screen. But getting the bad endings [[{{Omake}} is its own reward anyway]].

** Then there's filling the Treasury and getting all Followers and 5-Stars on every mission in ''[[VideoGame/SonicStorybookSeries Sonic and the Black Knight]]'' which requires playing all the Missions multiple times and most are really hard and even more annoying.

* ''VideoGame/ViewtifulJoe'' unlocks a new mode or character each time you complete the game on normal or harder with certain requirements. Unlocking Sylvia and V-Rated mode are fairly easy, but Super V-Rated, [[spoiler:Alastor, and Captain Blue]] to play are a bit harder - the toughest of which requires beating V-Rated or Super V-Rated with Rainbow V ranks in ''every single mission.''
** ''Viewtiful Joe 2'' also has the harder difficulties unlocked by beating the game, but instead of new characters has the 36 Chambers unlocked when certain achievements are performed. True completion means unlocking everything and beating all 36 Chambers with a Rainbow V rating.

* To 100% ''VideoGame/GeometryDash'', you need to unlock all ~450 character creator items<ref>Which includes all colors, all icons for all 7 gamemodes, all trails, all death effects and a glow toggle</ref>. For this, you need to get all the achievements, which includes beating 60 demons, 100%-ing official levels, beating over a thousand star rated custom levels and the hardest is getting a star rate at your own level. However, apart from getting all the achievements, you also have to open all finite chests (which requires beating all Gauntlets) and buying everything in the shops, because these are not included in any achievements and still they do unlock character creator items.
** There is also one condition that is highly arguable, which is getting all golden coins. Their amount is limited and equals 149 for the past 6 years, but to obtain them all, you have to beat those very annoying old map packs, and there are no achievements/unlockable stuff for getting over 130 golden coins besides the coins themselves.

* Achieving 100% (out of 101%) in ''VideoGame/JakAndDaxterThePrecursorLegacy'' will net you a bonus ending. All ten ambiguous seconds of it. The UpdatedRerelease gives a platinum trophy upon getting 100%.

* ''VideoGame/Splatoon2'' silently tracks your completion of the single player "Hero Mode" campaign. Beating every level, which you have to do anyway, nets you 100% completion. Meanwhile, beating every level with every weapon nets you [[Over100PercentCompletion 1000% completion]], with the player getting rewarded with the Replicia Hero Weapons ([[CosmeticAward reskinned versions]] of the base weapons) for undergoing that ([[ThatOneSidequest frustrating]]) extra mile. You can only see your completion percentage with the [=SplatNet2=] companion phone app, though.

** The amount of "collectibles" has been greatly increased for ''VideoGame/LEGOStarWars II'' as compared to ''LEGO Star WarsL The Video Game'', with red power bricks.

** In ''VideoGame/LEGOStarWars'' (1), collecting all of the minikit pieces from a chapter got you a single piece of a larger ship. Getting all Minikits and True Jedi Status for every chapter unlocked the Episode 4 preview.
** The amount of "collectibles" has been greatly increased for ''VideoGame/LEGOStarWars II'' as compared to ''LEGO Star Wars'' (1), with red power bricks.
** In the DS versions, though, it's made tougher by the fact that in vehicle levels, in order to get a minikit piece, ''[[NoDeathRun you must not die]]''.
** This is made easier when you find the 'Invulnerable' red brick. Then you can't die no matter what you do.
*** In ''LEGO Star Wars: The Skywalker Saga'', getting 100% requires you to collect '''''1166''''' Kyber Bricks, 225 minikits, 380 characters, 69 starships, 5 capital ships, 45 micro ships, and 19 datacards, unlock all 24 planets and the 19 extras tied to the datacards, complete all 9 episodes, 135 level challenges, 45 True Jedi meters, 140 side missions, 731 puzzles, 38 trials, and 10 challenges, and fully upgrade all the core abilities and all 9 character classes. Chances are by the time you finished the entire story mode, you’ll won’t even have collected a quarter of the Kyber Bricks. And that’s just the base game.

* ''VideoGame/{{Metroid}}'' provides a series-long example:
** ''VideoGame/SuperMetroid'': Every game since this one has a percentage (which in the case of that game and the console ''Prime'' games is easy to deduce, since the games have each exactly 100 collectibles). While earlier games in the series, including ''Super Metroid'' itself, gave different endings based on completion time rather than percent, percent has since become a factor in determining which ending you get.
** ''VideoGame/MetroidZeroMission'' actually features two prizes for getting 15% or lower.[[note]]One for 15% in Normal mode, and one for 15% in Hard mode.[[/note]] 9 items are required to complete the game, and it's generally recommended you fill five of the remaining slots on Super Missiles and Energy Tanks, with the last slot going to either Screw Attack or Speed Booster. Either way, you'll need to have mastered the game and Bomb Jumps. The European version can be completed on both Normal and Hard with a minimum of 9%, but the Japanese and US versions require a 10% completion rating on Hard due to a quirk at the end of the game concerning destructible blocks.
** Item collection fully displaces time regarding true completion in the 3D games (''VideoGame/MetroidPrimeTrilogy'' and ''VideoGame/MetroidOtherM'') for technical reasons. Completing each ''Prime'' game at 75% gets you a [[SamusIsAGirl face reveal]] during the ending, while 100% nets you a [[SequelHook foreboding]] PostCreditsScene. Note that the ''Prime'' games also have a separate percentage for the logbook scans, for which there's unlockable material for completion as well. Players of the ''Trilogy'' compilation itself can get a whopping 300% completion, or 100% per game. In the case of ''Other M'', collecting all items will unlock the path to a TrueFinalBoss ([[spoiler:Phantoon, of ''Super Metroid'' fame]]), and defeating it plus doing the traditional escape sequence will unlock the true ending; note that Hard Mode removes all pickups, and the game ends after the traditional FinalBoss is defeated.
** In ''VideoGame/MetroidSamusReturns'', each of the nine zones (the eight underground areas plus the surface) has its own percentage meter, based on the pickups and powerups present there. For every 25% you get, one of the four segments of the Chozo art gallery page associated with that area will be unveiled in the Extras menu. Naturally, getting all 100% will unveil the full page, and doing that to all areas in the game will unlock an extra page that shows an interesting (if also unsettling) scene involving the Chozo tribe.

** Each game since ''VideoGame/SuperMetroid'' has a percentage (which in ''Super Metroid''[='s=] case is easy to deduce, since the game has exactly 100 collectibles). While earlier games in the series, including ''Super Metroid'' itself, gave different endings based on completion time rather than percent, percent has now become a factor in determining which ending you get.

* ''VideoGame/{{Doom}}'' had several goals to shoot for per level: a time target, monsters killed, and secrets found. On Nightmare difficulty, however, monsters would respawn, making it possible to get more than 100% monsters killed, and at least one 'Doom construction kit' actually advocates creating a 'secret area' that the player can't reach, to keep them coming back to look for [[LastLousyPoint 'that last 10 percent']].
* This is actually carried forward from ''VideoGame/Wolfenstein3D'', although there is more incentive to get 100% completion for each category (kills, secrets and treasure collected) because you are awarded [[ScoringPoints bonus points]] for doing so.

* ''VideoGame/TheWorldEndsWithYou'' has 22 secret reports, 96 Noise reports, 472 items, and 304 pins to collect (and a {{Speedrun}} BossRush which only counts on tougher difficulties). Completing each set gets you a star rank for that collection and a new character on the save screen. Collecting all the secret reports also unlocks TheStinger. Then there's your [=ESP'er=] score... You gain one point for each battle cleared and each item bought worth more than 10,000 yen. And you need ''exactly'' 10,000 points in the US version to achieve God rank. One more and you're back down to Demon.

* Each game in the original ''[[VideoGame/SpyroTheDragon Spyro]]'' trilogy brought different rewards for 100% completion: The BigBad's treasure vault in the first game, an unlimited supercharged flame breath in the second, and a final level with tons of treasure and the last [[MacGuffin dragon egg]] in the third.
** In Spyro 2, after you get that eternal superflame, [[NewGamePlus save the game, start the game over (without resetting the console), and dominate EVERYTHING]]!
** The third one had what is possibly one of the most satisfying of all 100% completion rewards. After you collect every gem and every dragon egg, you meet Moneybags, the irritating bear that you had to pay so many precious gems to get him to do things like lower a bridge or start a fan. He reveals that he has found one of the dragon eggs and intends to sell it for a fortune back in Avalar (where the second game took place). What follows is the player chasing him around, ramming into him horns-first (or [[KillItWithFire roasting him]], whichever you prefer) until he coughs up every last gem he took from you.
** ''Season of Ice'' took this to the extreme: you had to have 100% to finish the game.
