Well, come this March 1^st we will get to see another protagonist, from Extraction, try to fit into Isaac's Rig to add another two chapters to Dead Space 2. This all coming in the form of DLC titled Severed for the low price of 560 Microsoft points or $6.99. Doesn't seem too bad for two new chapters explaining some of the other events taking place within the game's universe.

Looks interesting to me. Although I don't remember Gabe having the different looking rig in the first place, but I guess he could have just upgraded. I know I'm interested to see what exactly happened to Lexine since we last saw her.

^* Purely my take on the events and scenes
