The Bumper Cars trap is unique in which once the Power Switch for that area has been turned on, the cars will automatically start driving straight forward and backwards in turns. The trap is free to use and can be useful to kill zombies when the player is low on cash. The Bumper Cars can be dangerous to the player, instantly downing them if hit by the cars. The cars will flash their headlights shortly before moving.
Bumper Cars are found when taking an exit out of the Astrocade towards Journey into Space, they are at the end of the Journey into Space zone coming from the main Junction.
