Leading this week's offerings are add-on packs for Evolution Studios' dirt racer MotorStorm and Team Ninja's action game Ninja Gaiden Sigma. The MotorStorm Weekend Add-On Pack includes a new track, four new vehicles, nine additional races, and a new online mode and is available for $5.99. The new vehicles waiting to be caked with mud are the Wakazashi Razor bike, Wombat Mudslide ATV, Atlast Varjack mudplugger, and Atlas Arizona big rig. Each vehicle is also available as a stand-alone download for $0.99.
Also available is the Ninja Gaiden Sigma Weapons Master Add-On for $2.99. The first of three planned updates, the Weapons Master pack augments the game with five survival modes.
The PlayStation 3's growing pile of game demos also expands by two this week. Though the full version of Midway's Stranglehold was pushed back to September 25, the free trial can now be had on the PSN. EA Sports is also passing off its third demo in two weeks to the service with a trial of NBA Live 08. NBA Live 08 will officially take the court October 2.
