Classic Game Room reviews GOD OF WAR: CHAINS OF OLYMPUS for Sony PSP. This 2008 video game for the Sony PSP is a prequel to the 2005 megahit God of War for the Playstation 2. You are Kratos, champion to the gods! Slaughter enemies and bosses without mercy using button combinations and quicktime events. Tear enemies limb from limb, rip their heads off and meet some lovely ladies who just want to "party". It's all in a day's work for Kratos, the God of War.
