Section 8 is a FPS that has recently gone into beta testing. The PC version totally owns the xbox360 version, thus why I am posting about mostly the PC version.
The game is similar to Planetside and Tribes if any readers have played these. The game features 16 vs 16 matches with and without NPC bots, up to 5 classes which can be customized at almost any time. There are 7[?] weapons to choose from, around the same number of side equipment to use [grenades, mortar, radar items, repair tool, etc] and like I said a customizable class feature where you can fine tune how each class works, etc.
The PC version also supports the XBOX360 wired controller. I use this personally and it rapes lol
The beta currently has 2 maps and a few game types as far as I know.

The full version as far as I know comes out in 3 days for North America.
Get out there and game people! "Godspeed!" [in game joke] =P
