It's actually not that great, it mimics a lot of better games out there.
The realism aspect is there, but it all feels like a sandbox kind of game. Like someone made this in their basement or something. The movements with the mouse and keyboard just don't feel right, like when you play a bad port or something.
I kinda bought it to see what all the talk about the realism is about but its really nothing but no radar and very limited hud. Plus some pretty big recoil and slow weapon switching/reloading. The effects when bullets are flying by you and the granades that go off next to you are pretty neat i have to say. They really mess up your aim, but then again day of defeat has the same feature.
The maps are decent and its really cool that you can drive a tank but it seems to me that the game is primarely for sniper affectionados that just love to sit in that same spot all day. Not that camping isn't fun but the game makes it a little too unbalanced on that aspect.
Overall i don't think its that good of a game. Unless you really love sniping and sitting around all day then you might actually like this.
I think it just lacks the action packed aspect necessary for a good multiplayer.
