Demolition Derby is a racing game developed by Bally Midway and released as an arcade video game in 1985.
The player takes part in a demolition derby. Hit other cars in the radiator to damage them, while avoiding being hit in one's own radiator. Power-ups include wrenches, screwdrivers and car keys.
A notable feature of the multiplayer mode was the ability to enter a game while it is in progress; the message "CAR ENTERING DERBY" would appear on screen.
Demolition Derby was listed in the book 1001 Video Games You Must Play Before You Die.
