This is a good map but you need speed and a gun with a fast fire rate. Tried my DSR and there is sniper positions but it is a running map primarily. Camp and you're dead. It's confusing in its layout but I got used to it after a couple of games.
The basement is a bit like death room. Plenty of crates and containers. I've already noticed that everyone is using mines and hornets. A 140 kill game takes a long time even on 8 v 8. Main thing is take in a gun that fires fast.
