The player (or players, since the two players can play simultaneously making the game much more competitive) must defend a deposit of ammunition from enemy attacks that with surface vehicles try to steal them by taking them off the screen. Each enemy destroyed increases points. The game ends when all the ammunition has been stolen.

The cabinet in the collection is the Italian version produced under license by ZACCARIA of the US game RIP OFF by Cinematronics. It is very rare and in  excellent condition and also has a sort of elegance in the choice of shape and chrome.
