How many GB is Protocell?

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.

Mutation is evolution. A lab cell broke containment — pilot it through swarming arenas where every upgrade you take drags you closer to meltdown. Grow billions of one-of-a-kind protocells, hand any of them to a friend with a 16-character code, and dive into the Primordial Abyss.
