yes, you can play it. It's operation rattrap on objective mode. each gun has its own person inside manning it (if you're playing online.) It takes two gammon grenades in the ammunition dump to destroy. you need three to blow one of the tiger turrets on the outside, then you need to destroy three doorways to get to the ammo dump. also, if you blow it up, you don't survive, you can't get out in time. you can watch from about 300-500 meters away, i foy don't want to die in the huge atomic-bomb like explosion. When it's going to blow up, the klaxons from the sinking ships play along with a bunch of crewmembers shouting and clamoring to get away before it blows.
It's awesome, in short.
