Every 30 seconds a plane drops a SHIELD on a rooftop: grab it for 15 seconds of immunity to knives and bombs. In Team Deathmatch your teammates cannot hurt you and you cannot hurt them. Bombs bounce, fuse for two seconds and explode on contact with a player. Your own blast hurts you less, and it can launch you onto higher roofs. Score is kills minus deaths, and falling off a roof counts as a death.
