Im surprised this has not been mentioned, had my eye on it for a while but arma requires enough attention let alone 2 games for now, looks very good though.
I've got my eyes on this game, too, but quite honestly, it's "yet another" tactical shooter. I mean, it's well done, graphics are great, and the mechanics look great, but in essence, Arma can do the same, in fact, Tactical Battlefield is exactly that.
Also, CiA is not really interested in PvP or TvT, so it's no wonder it's not been mentioned.
I'm sure the game is good, and I might get it at one point, but I'm a bit afraid that it's basically like the other shooters that you play on public servers: Just a bunch of guys playing for themselves, with little cohesion or communication.
