Twisted Metal 4 is a vehicular combat video game developed by 989 Studios and published by Sony Computer Entertainment for the PlayStation. The game was released in North America on October 31, 1999 and was re-released for the Sony Greatest Hits line-up in 2000.
Twisted Metal 4 is the fourth installment in the Twisted Metal series and the second and last installment to be developed by 989 Studios. The game's plot centers on Sweet Tooth, the long-time mascot of the titular Twisted Metal competition, overthrowing Calypso, the mysterious organizer of the competition, in a coup d'état. He then takes over the mantle of granting the winner of the competition a single wish, regardless of price, size or even reality.
In concept, Twisted Metal 4 is a demolition derby which permits the usage of ballistic projectiles. Players choose a vehicle and an arena (or a series of arenas in the story mode) to engage in battle with opposing drivers. A variety of weapons are obtainable by pick-ups scattered throughout the stage. The objective of the game is to be the last one standing.
