Unga Bunga

Unga Bunga is a multiplayer platform/deathmatch hybrid for 1 to 3 players, in which the players run around as club-wielding cavemen in exotic habitats, kill moose and bears to gain technology (which allows them to use better weapons, including spears, traps, firesticks, coals, bow and arrow, sword), fend off invading philistines, and ultimately compete with eachother for various objectives (depending on the game type). All aspects of the game are fully customizable, and replay is practically unlimited. Oh, and did we mention that its fun?
