Duel Blasters 3000 is a homebrew PC game by Erotic Nemesis, which features somewhat racy themes (not safe for work, etc). It's made to be played with two players, and plays a bit like Windjammers with shooting. The game also has some very cool easter eggs that I wasn't supposed to mention. But seriously. Seek them out. Great music too, which you can download on its own. Is very recommend. The guy in charge of this, one Jack Dark has more projects up his sleeve, and I would not be surprised if they were excellent.
