How many GB is Atomic Heart: Annihilation Instinct?

90 GB

That makes it bigger than 97% of Shooter games we have measured.

The median Shooter game needs 4 GB; the largest tenth start at 40 GB.

Leave at least 113 GB free: games need headroom to unpack updates.

The figure is the storage Steam lists as required for this game, not a measured download.

Continue the story in the Annihilation Instinct DLC and learn what happened to this dystopian world after the climax of Atomic Heart. Prepare to embark on a journey through the new mind-bending Mendeleev Complex and its surrounding swamps, and discover the truth about NORA as Major P-3 is pulled back into Facility 3826. Survive vicious, shape-shifting new enemies and take them down using two cunning new weapons - ranged one the Secateur and melee one the Klusha - as well as your glove’s new Techno-Stasis ability, allowing you to manipulate time itself. Meet a new enigmatic character, as well as returning ones in surprising circumstances and dive deep into the AI’s insanity to curb its Annihilation Instinct.
