An Isaac Prototype Suit, from the excellent Dead Space 2, can now be bought inside PlayStation Home. The suit is available from Alter Ego, which is also stocking what can only be described as the most hideous outfit I've ever seen.
Elsewhere in Home, there's a Mad Scientist Start Kit in the Loot store, a tentacle ornament in the nDreams store, and a Cow Sofa in the Furniture store. If you're still looking for new things to buy, how about a horse, dog or rabbit from the Home Stuff store?
We awarded Dead Space 2 an impressive 8/10 on its release earlier in the year.
