Not much is known about the upcoming addon for Dead Space 2, titled Severed, other than it will follow both Gabe and Lexine (both characters from Extraction). It will feature 2 chapters and players will assume control of Gabe, who was stationed as a security guard on the Sprawl. No story details have been provided other than EA saying that these 2 chapters will happen in parallel to Isaac’s story in DS2.
For now, all we have are these two pieces of concept art, depicting Lexine’s model and Gabe sporting a new suit. Check ’em out.
