History VideoGame / DaemonXMachina

* MultipleEndings: Zigzagged, as it's more of a LastSecondEndingChoice. [[spoiler:After you've defeated the Dominator, Grief/Four asks you what you will do: "Fulfill Life's Purpose" and lower the Oval Shields, thereby allowing Femto to flood the world and force humanity to adapt; or "Search for Hope" where the Rookie is entrusted with the future by the Dominator, though the Oval Shields ultimately fail on their own anyway, just at a more gradual pace, ostensibly allowing humanity to acclimate slowly instead of being exposed in massive doses [[SurvivalOfTheFittest that only the hardiest and most prepared]] (read:the Reclaimers themselves) survive.]] The only difference between the endings is that [[spoiler:one has the Rookie and Grief both being listed as MIA and the other shows them returning to the rest of the Reclaimers.]]

** When looting Arsenals for parts, gear ther player don't own is marked with a blue symbol (or with their name written in yellow in the PC version) so you can immediately tell whether or not it's something you already have. If you sell a part or use it for research it will regain this mark, which makes keeping track of what parts you currently have much simpler.

** More for [[spoiler:the final boss]], the battle music is [[VideoGame/AceCombatZero the occasional orchestral moment scattered throughout a rip-roaring flamenco piece]], fitting as it doesn't care about the boundaries drawn by the Oval Link.

* WeaponOfChoice: There are many weapons to choose from for different builds and play styles.

* ToxicPhlebotinum: Femto is a mysterious pseudo-radioactive substance from the broken moon that borrows traits from [[Franchise/MassEffect Element Zero]], [[VideoGame/ArmoredCore4 Kojima]] [[VideoGame/ArmoredCoreForAnswer Particles]], and [[VideoGame/MetroidPrimeTrilogy Phazon]]. It is deadly toxic to most humans, but the ones who survive exposure to it develop [[ILoveNuclearPower supernatural powers]] and become prime candidates for Arsenal pilots.

** [[spoiler: That machine is also [[VideoGame/DeusEx having difficulty deciding]] whether they want the BigBad or TheHero as their human component, and should the latter choose to replace the former, together they usher in a new era for humanity, though not without grave costs. And in case you think it's just a coincidence, the machine outright calls itself "the [[TitleDrop Deus Ex Machina]]" in one ending.]]

** The game has more than a few to its ancestor, ''VideoGame/ArmoredCore''. Just for starters, the standard assault rifle is called the Silver '''Raven''', named after what mercenaries are called in that series. One of Innocence's pilots is also named "Crow," keeping the corvid theme. And Radiant Gleam, the default Arsenal used in promotional art for the game, is an obvious reference to [[VideoGame/ArmoredCore4 White]] [[VideoGame/ArmoredCoreForAnswer Glint]], another mech designed by Creator/ShojiKawamori. And lastly, one early mission features a long vertical shaft similar to the final mission in the first ''VideoGame/ArmoredCore''. That mission's operation name? "Nine Ball".

On September 2021, during the game's second anniversary livestream, Tsukuda announced that a sequel is in the works.

* MiniMecha: All the available footage shows that the Arsenals are only 5 meters (~16 feet) tall.

* MacrossMissileMassacre: Gameplay footage shows an Arsenal equipped with a shoulder-mounted missile pod, which will launch multiple missiles at the enemies via MissileLockOn.

In the distant future, a fragment of the Moon collides with planet Earth, killing millions of people and radiating Femto, a strange energy that poisons and corrupts anything it touches. In desperation, the surviving governments establish a quarantine area around the impact zone called the Oval Link and turn to A.I. programming to assist with the logistics of rebuilding civilization, creating a massive, advanced artifical intelligence to oversee the rebuild operations. Upon coming in contact with Femto, however, the intelligence goes haywire, changes its objective from helping humans to annihilating them, and creates a new faction of enemies let by massive robotic beings called Immortals, with the faction itself called the Arms of Immortals, or AI for short. The AI attack Humanity's sanctums from Femto contamination, putting humanity in peril once again.

* ArmoredCoffins: Notably {{Averted}} when compared to ''VideoGame/ArmoredCore''. Not only can you eject from your Arsenal at any time, but you will do so automatically and without fail if it gets shot down[[labelnote:*]](unless it's a multiplayer mission, in which case you're given the option to stay put so that an ally can reboot you rather than risk getting [[FinalDeath killed permanently]] as an Outer)[[/labelnote]], letting you continue the mission on foot (though [[ControllableHelplessness don't expect to put up much of a fight in this state]]). [[spoiler:This also [[GameplayAndStoryIntegration applies to other Reclaimers,]] as very few Arsenal-to-Arsenal duels are to the death in this game, compared to ''Armored Core'' where almost all of them are.]]
