Off-World Interceptor is a rail-based off-road vehicular combat game, giving the player the ability to drive (and in some cases, fly) anywhere he so chooses. The player takes the role of a "trashman", a bounty hunter who chases after fugitives in order to earn money. A core element of the game is that the player's car can navigate unrealistically steep slopes, and can move infinitely to the left or right of the environment. The car itself is not explicitly locked to a rail, though the player cannot turn around or back up. Every car is armed with jump jets, devices that allow the car to both jump and fly, and all cars can pitch up or down for aiming purposes.
