If you're a PlayStation Plus member you also get a "full game trial" of God of War 1 and 2, which you can test drive for an hour apiece. Also, Trophies and game progress will roll over if you purchase the game after taking the blades out for a spin. While you're taking advantage of your membership, you should also check out the Vanquish trial.
There's plenty of more stuff in this update, so head on past the break for all the details.
Note: In addition to this week's update being really behind schedule, Sony is telling PSN users that, while all of the content is now live, it's not actually appearing in the PlayStation Store interface. You'll need to use the PS Store search function to find the new additions until the problem is addressed.
