It's that time of the week again, boys and girls. We've got this week's update for the PlayStation Network and PC PlayStation Store. The very beefy list includes two downloadable game offers, lots of add-on content, videos, and themes, among others.

This week, you can get Warhawk for a discounted price - the promo lasts for a couple of weeks until April 15, and you can also check out the flOw bundle which includes the game and the expansion pack. The add-ons for this PSN update includes the usual Rock Band songs (Boston Pack), plus downloadable songs for Karaoke Revolution Presents: American Idol Encore and additional maps for Unreal Tournament 3 (also on PC and Xbox 360) and Turok.

Check out the complete list below for this week's batch of PlayStation Network and PC PlayStation Store goodies.
