God of War: Chains of Olympus downloadable demo
Get your Greek on
Within the breached walls of Attica, Persian soldiers and a giant basilisk lizard are laying waste to all in their path. Only Kratos, endowed with superhuman strength and the lethal Blades of Chaos, can slay Attica's enemies and begin his path to redemption.
It really is one of the best gaming experiences the PSP has to offer so you'd be mad not to give this demo a try.
