Early in the game, Batman must locate the source of a sniper shot. The Joker reveals that the church the gun is found in is filled with explosives, but the tower will not explode immediately if the timer hits zero. Instead, the Joker will talk for a short period, hinting at key plot points from later in the game.

After his monologue, the Joker will warn the player that they "really ought to get out of there." If they do not leave, the bombs will indeed explode, leading to a Game Over.
