History VideoGame / Decision

* NothingIsScarier: In 2nd game, rambling in any cleared sector becomes this[[note]]especially at night[[/note]] as the area is almost devoid of all enemies and the background music is replaced by not-so-distant spooky noises, growls and almost heartbeat-like pounding. The atmosphere becomes like straight out of ''VideoGame/SilentHill''.

* ChromosomeCasting: You won't find a single female character in the entire series.

* FailedASpotCheck: If there's enough dead bodies piled on the ground a single land mine will blend in among them like a salt into water. If the mutant boss placed it you're in for an unpleasant surprise, especially [[PostMortemKill after bringing the behemoth down]]. %% Attack from far enough, and enemies won't react to their buddies dying or the explosions throwing them to the ground. Not so with bosses, who will hurl themselves halfway across the map to kill you.

* GroundPound: A player ability, in imitation of wolf mutants and bosses.

** In the first game, once you accomplish all objectives, the mission ends, so if you forgot to snatch somthing, it's beyond recovery now. The same goes for the entire game, once you gain control over all yones but still have some lingering achievements - there's no hope of getting them after that.

* Expy: The giant green zombie[[labelnote:and]]to a certain extent all giant zombies[[/labelnote]] is an obvious stand-in for the ''Comicbook/TheIncredibleHulk''.

* PermanentlyMissableContent: In the first game, once you accomplish all objectives, the mission ends, so if you forgot to snatch somthing, it's beyond recovery now. The same goes for the entire game, once you gain control over all yones but still have some lingering achievements - there's no hope of getting them after that.
** Thanks to the ''Jackpot'' achivement in the second game being a LuckBasedMission, it is completely possible that you'll hack

* CoolPet: One of the Masters in ''Medieval'' has a bald eagle as a ShoulderPet.

* MoreDakka: It's possible (but not a good idea) to upgrade an outpost with 3 gatling guns plus a trio of soldiers with assault rifles.

* MySpeciesDothProtestTooMuch: You can encounter several friendly orcs in ''Medieval'', one of which teaches the ultimate abilities after you've proven your worth.

* SinisterScrapingSound: If you hear scraping, a manhole has just opened and will soon release multiple werewolf mutants. You should run.

* TookALevelInDumbass: By ''3'', zombies are limited to melee attacks, when ''2'' had them able to use guns and throw random debris at you.

The series currently has four games:

#''Decision: Red Daze:'' The fourth game in the series, and the first commercial and non-Flash one, this game features many of the mechanics that made the series popular, and adds, among other things, fully customizable survivors and unique boss zombies leading the hordes. It was released on Steam and GOG in May 23, 2022.

#''Decision: Medieval:'' Released a couple of months before Decision 3, this game features a [[ExactlyWhatItSaysOnTheTin medieval theme]] with a greater focus on melee combat, but it also shares several elements from Decision 3, including inspectors (called "Masters" in this game) and a second threat in addition to the zombies.

* GameplayAllyImmortality: {{NPC}}s you bring with you and those necessary to the mission don't die, they just fall to the ground and stay there unti yo come near them and there are no enemies around. Non-critical [=NPCs=] are entirely vulnerable (and it's quite possible to come across their mangled corpses before you even had a chance to rescue them).

Non-critical NPCs are entirely vulnerable (and it's quite possible to come across their mangled corpses before you even had a chance to rescue them).

* MadeOfExplodium: Barrels will always explode when shot enough times. ATMs in ''2'' will also explode if shot enough times. ''2'' and ''3'' also add huge tanks with nuclear symbols on them, capable of easily killing a player if they're standing too close. ''Medieval'' uses gunpowder instead.

** Killing ATMs also gets a small amount of money, and they respawn until hacked.
