The Shooting Gallery during Wrong New Guy's tour. The power generator is in the back.
As its name suggests, The Shooting Gallery is the shooting gallery in Base 327. For unknown reasons, the power generator is in it, right behind the targets. This proved to be a bad idea when, during the Wrong New Guy's tour, a clone hit it and caused an explosion. The gallery was known to use B1 and B2 battle droids and IG assassin droids. These droids are capable of returning fire.
