be a sniper,dont use noob tubes they dont work unless your an expert noob with them and can place them at the right spot at the right time otherwise its just luck because one strategy can work 1 game then the next it will just fall flat on its face
on offense and defense on that map i like assault rifles (ak47, m4 or m16) with red dot or acog bomb squad on offense claymores on defense other two perks will vary depending on my mood.
