This weekend (now-6/7) Steam will be allowing users to download and play Shattered Horizons, a sci-fi FPS set in space. This promotion coincides with the free weapons patch that they released recently, and you can buy the game for 50% off over the promotion (normally 15$)
And when I say set in space, I mean it. Every player is equipped with a space suit and a jetpack as well as their guns. The entire game takes place in zero-gravity, allowing for 360 degrees of movement at all times, although you can align yourself with objects to allow accurate shooting.
I played the game the last time they did this promotion, it really is quite fun. The arbitrary movement through space is something of a unique thing for FPSes. If anything, try it out just for the interesting mechanics.
