US PS Store Update, January 25: Dead Space Extraction, Bulletstorm demo

This week's US PlayStation store update carried two major players - a port of previously Wii-exclusive prequel Dead Space Extraction, and demo for "big dumb shooter" Bulletstorm.

Rock Band 3's David Bowie DLC made a welcome appearance, as did the promised avatar deluge.
