Interstellar Marines (free bullseye game available)

Interstellar Marines is a PC shooter being developed by Zero Point Software for the PC, Xbox 360, and PS3 (PC version coming first). They're calling it a AAA indie game, which basically means they are boasting big budget, big project, high quality, but still remaining independent. They are also asking for help from the community to fund the project since they aren't relying on any big name publishers (contributers also get special status and perks like beta priority).

You can check out the Bullseye game they've released which puts you in a fancy shooting range with tons of different game modes and the ability to track your scores on leaderboards and earn achievements and stuff.

You can play the game here.

You don't have to make an account to play but you should make one so you can save your progress and earn achievements.

Did I mention it runs in your browser? (use firefox)

And while you're at it, check out the vault. It uses the same technology as Bullseye but you get to run around and look at previews of some of the enemies and stuff in the game. They also have a lot of videos and stuff up on their site.
