Oh my wow, the lightsaber works again. Don't know if you can do anything about this but there's a little trick that you can do with the gas gun and almost any projectile that goes in an arc or is an explosive. Say I'm in PZ, I shoot an explosive gas shell in the lobby and enter the next room before it hits the floor, the shot will carry on over to the next level and where it lands is dependent on where you were facing. This is sometimes abused in multiple bases because you can fire a shot, enter the next room, and hit someone at the back of the next level.
