It came out a few days ago, and it will finish next week sometime.
It seems to me a mix of CoD and Halo, but it's really well done. If you happen to try it out, and after the first hour or so decide you don't like it, stick at it for a bit. Me and a couple of other friends have found that most people seem to really start having a blast after they've put in a bit more gameplay.
I'm really loving it and can't wait for the full game in March!
