Positech games has announced that their latest expansion pack for their PC strategy game
Gratuitous Space Battles, titled The Parasites, is now available for download from their site, with digital distribution soon to follow. On top of that, they're also working on a new game called Gratuitous Tank Battles, which is inspired by GSB, and is scheduled for release "at some time before the heat-death of the universe". I guess that's one was of saying it'll be ready when it's ready.
