EA’s launched Dead Space 2 DLC Severed on Xbox Live. It’s based on Extraction characters Gabe and Lexine, as he goes through the Sprawl to save her. Severed’s story acts in parallel with Issac’s story in the main game itself. The content, which you can queue up here, sets you back 560 MS points and is 1.43Gb in file size. PSN gets it tonight in the US and EU tomorrow.
