 The two-player option was inspired by then-current games "Populous" and "Stunt Car Racer".DMA Design initially wanted to use a null-modem connection between two machines to allow competitive play, but ended up using the ability of the Amiga to have two mouse pointer devices usable at the same time and thus created the split-screen mode.The popularity of the game on the Amiga led to its rapid porting to many other platforms, and it is regarded as one of the most widely ported video games.
