Cavern City was constructed along a massive trench some time after the Malcontent Uprisings, and was located somewhere in South America. It was once a prosperous trading post that was hit hard after the economy tanked following successive wars with alien forces. Following the Invid Invasion, the city became the battleground for two major biker gangs, the Blue Angels and the Red Snakes. Both gangs vied for dominance, with the Blue Angels eventually losing and disbanding.
