Devious is based on the arcade game Xevious. The original arcade game was famous for using some pre-rendered, three-dimensional type shapes, but the Coco 1/2 could not duplicate this kind of graphics. The game also ran a little slow, and was greatly aided by the advent of the Coco 3, and the double speed POKE. The game was a little unique in that it had two firing modes, since the Coco only had a one button joystick at the time, but was trying to duplicate the arcade game which had both a guns button, and a bombs button.
