How many GB is Ammossum?

2 GB

That is less than the typical Shooter game, which needs about 8 GB.

Leave at least 8 GB free: games need headroom to unpack updates.

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

Build an endlessly upgradable weapon! Evolve projectiles into unstoppable firepower in this action roguelike. Fight through hordes of infected beasts, save your family, and feel the thrill of bloody shootouts filled with bullets, explosions, and acid. Can you survive the madness?
