Mass Effect N7 armor and M8 rifle, plus not to mention, my personal favorite, the BioShock Big Daddy costume, Harrison Krix.
This time, he is back with his Portal 2 gun replica. His first Portal gun was made last year and was put up for auction for charity for Child's Play. The gun sold for $14,000. The Portal 2 gun will be upgraded with a potato. If you are looking for a great replica for the gun Chell uses in the sequel, this is it!
