Has anyone else tried this?
Had a go other night and relatively impressed. It's really smooth, it's very fast paced and old school (somewhere between q2 and UT2k). As someone who thinks the BF and COD games are an abhorrent scar on the very nature of competitive FPS games, this is a welcome, refreshing change.
Anyway it's free to play the open beta, I recommend giving it a whirl.
