Sony Computer Entertainment America (SCEA) also released a pair of new trailers for God of War: Ghost of Sparta, a PSP game developed by Ready At Dawn Studios, the team that developed God of War: Chains of Olympus. Set in the realm of Greek mythology, God of War: Ghost of Sparta is a single-player game that allows players to take on the powerful role of Spartan warrior Kratos. This new adventure picks up after God of War concludes, telling the story of Kratos' ascension to power as the God of War. In his quest to rid himself of the nightmares that haunt him, Kratos must embark on a journey that will reveal the origins of lost worlds, and finally answer long-awaited questions about his dark past. Armed with the deadly chained Blades of Chaos, he will have to overcome armies of mythological monsters, legions of undead soldiers, and dangerous and brutal landscapes throughout his merciless quest.
