ARS: As the demo for God of War: Ghost of Sparta on the PSP begins, you're on a ship sailing toward Atlantis. You fight on the boat, you land, and you fight on the land. It gives you a feel for the new weapons—a spear and a shield—as well as the new attack, a charging move that lets you pick up and throw down an enemy to punish him on the ground. It looks stunning on the PSP, with water effects and a steady frame rate. The problem is... well, haven't we seen all this before?
