Little over a week after its predecessor came to Steam, Descent 2 is now available on Valve's digital distribution platform. You can grab Descent 2 on Windows PC for $10 right now.

Descent 2 takes place directly after the events of the first 3D first-person shooter. At the outset of Descent 2, players are outfitted with an experimental warp core and blackmailed into exploring mines beyond our solar system. The sequel was initially planned as an expansion, but due to the popularity of the first game, Descent 2 was fleshed out to be a full-fledged follow-up.
