Saw this title advertised on Steam, it's due to come out early March, looks interesting, it uses ingame points/cash based system where you buy weapons/vehicles during game play (kinda like Killstreak Rewards) which I think would make it a more unique FPS experience. There's a few good videos in the Steam Store. Let me know what you think.
