Cast Away is a 3D real-time artillery game in which the player takes on the role of an eccentric sea-captain, stranded on a small tropical island and pitted against a rival sea-captain on a nearby island.

The game is played in the third person, having the player collect various items around the island to lob at the enemy using a makeshift catapult. Some things can be combined to create exciting effects using the combo system.

The player can move the catapult around to dodge enemy fire as well as detach from it to collect items faster.
