How many GB is Kessler Syndrome?

2 GB

That is less than the typical Simulator game, which needs about 4 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.

Alone in orbit with a corpse and no way to reach Earth, play as an astronaut who must keep a defunct space station aloft. Maintain the onboard systems, deal with the constant threat of space junk, and navigate the dark halls in zero-gravity. Day by day more systems fail, and the void draws closer.
