Set in prehistoric times, CHUCK ROCK follows the exploits of the title character as he searches for his wife Ophelia, who has been kidnapped by a knuckle-dragger named Gary Gritter. You'll have to get through 19 levels in five bizarre worlds, through the jungle, in a volcano, a primordial swamp, the Ice Age, and a dinosaur graveyard, fighting everything from dinosaurs to boogie men as you pursue Gritter. Chuck has a few tricks up his sleeve, like belly-bashes, odor-kicks, and rock-tossing, to take out his enemies and proceed through the levels. Along the way, he can also pick up various power-ups and items that will help his cause. Will Chuck be able to save his wife from Gritter?
