As a man or woman stranded naked, freezing & starving on a mysterious island, you must hunt, harvest, craft items, grow crops, & build shelters to survive. Use skill and cunning to kill or tame & ride the Dinosaurs & primeval creatures roaming the land, & team up with hundreds of players or play locally!
