How many GB is Fission Superstar X?

0.1 GB

That is less than the typical Role-playing (RPG) game, which needs about 6 GB.

Leave at least 6 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 off in Dr. Leopold's bomber in this relentless rogue-lite shooter. Tour the solar system on a desperate randomly generated bomb run. Face impossible odds trying to achieve the demented dream of an insane scientist.
