The idea behind this is certainly interesting. It's an adventure starring a spider and a scorpion with a human story overheard in snippets of dialogue as the creepy-crawly heroes cross the paths of a pair of human treasure-hunters in the desert.
In one level you'll play the spider, pursuing its scorpion rival through the undergrowth. After a quick fight, the scorpion escapes through a crack in the rock and becomes the playable character for the next level. Gameplay alternates between the two and there are recurring enemies, such as a giant rattlesnake and the two men.
