How many GB is Demon Spore?

0.88 GB

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

Blast your way out of tentacle hell as a failed lab experiment gives birth to a rapidly growing viral horror in this intense action rogue-lite inspired by 80s Monster movies. Use the lab to your advantage and improvise an escape plan before this constantly evolving life form spreads out of control.
