How many GB is Immunity Protocol?

1 GB

That is less than the typical Indie game, which needs about 3 GB.

Leave at least 7 GB free: games need headroom to unpack updates.

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

Pilot an immune-cell sentinel in a neon pixel-art horde-survival auto-shooter. Move manually, auto-fire evolving weapons, draft upgrades, equip symbiotes, and survive escalating pathogen swarms inside a collapsing biotech system.
