This is a really great retro-ish space shooter that is pretty unique. I picked it up on Desura a while back and come back to it a lot. Lots of exploring, lots of battles, plenty of equipment upgrades... Considering the Asteroids-ish setting, there's really a lot going on here. The dev is a guy in college so I don't know if this is an ongoing project, but it's on greenlight and it's darn near perfect as it stands. Highly recommended.
Game Title: Space - The Return of the Pixxelfrazzer
