Attack of the Mutant Camels for the Atari was a lot prettier and more smooth than its Commodore counterpart. The camels, although rather chunky, were at least more camel-shaped than the ones in the C64 version; the background scroll was smoother, and the horizons were really nice, due to the judicious use of Display List Interrupts on the Atari, and all the nice colour one could use on those machines. The camels also broke up in rather nice Robotron-style explosions when you offed them.The package artwork was rather nicer too!
