If you are a paying subscriber to the bonus program PlayStation Plus then you're in for a treat this week (well, if you own a PSP that is). The God of War: Ghost of Sparta demo has been released in all of it's bloody glory. The second portable God of War game from Ready at Dawn chronicles the quest for Kratos to end his nightmares once and for all. The storyline picks up where the original God of War title left off (before God of War II began). Ghost of Sparta will be released in the fourth quarter of 2010 for $39.99 MSRP and is rated M for Mature.
