I am trying to think of the title of this movie, it was an 80's flick, it was set in a post apocalyptic world, and the planet was a desert and everyone lived underground. THe movie was centered around a gruesome game that was played with 4-5 players. One player had a nasty tire chain, one player had a staff witha hook on the end, one player had like claws, and another player, the fastest battled for a stone thing. The game was times by a dude that threw marbles at a wall.
