Bulletstorm's new Gun Sonata DLC, out today for the Xbox 360 and PS3 versions of Epic's balls-to-the-wall (literally!) FPS, should help satisfy that primal need.
The pack, well, packs two new Echoes mode maps (Guns of Stygia and Crash Site) along with three more locales for Anarchy mode (Hotel Elysium, Sewers and Villa) for the sum of 800 Microsoft Points / $10 on Xbox Live and PSN, respectively. The content is up on XBL now and will hit PSN with its weekly update this evening. As for the PC version, EA tells us it's still planned, just without a firm release date at this point.
