Me, Tristan, Anders, and a couple other guys were absolutely owning for nearly an hour on offense in this mode. Even all of us combined + a bunch of other fellers with huge scores, rather stomping the server, simply could not crack a single spawn point when it only had one ladder as entrance with weapon rack and healing tent. No matter how many people we killed, more would respawn, seemingly instantly.
Great mode, but I haven't seen attackers win a single round yet.
