About
Two in the Chamber is a one life per round pvp game mode where you have a double-barrelled shotgun loaded with a buckshot (medium range spray) and a slug (long range one bullet) and also a knife! Getting a kill is the only way to replenish your ammo. Movement is fairly fast and has double jump and wall running.
Wall Running
Jump into a wall fast enough and at the correct angle to start wall running. Wall running refunds your double jump, so you can chain wall running and double jumps.
