I played it a while ago for a few hours total. Having owned BF2 + Special Forces, it wasn't worth playing over BF2, but I did give it a chance. Being free there is some sketchy things about the game, but it does play ok and is fairly fun. So yeah if this type of game interests you, it's definitely worth the free download and a couple hours of play. Though personally I'd pick up BF2 or something like it, since it can be found for perhaps $20 used.
