Why does it look so fake? If this is real then that's pretty fucking cool.
Considering you could unlock Megaman's outfit in the first Dead Rising (with the Mega Buster included) I doubt this is fake.
You can always unlock a Capcom character costume in each Dead Rising game, except for Case Zero. Megaman in Dead Rising 1, The guy from Bionic Commando in Chop till you drop, Arthur from Ghost n' Goblins in Dead Rising 2, Dr. Willy in Dead Rising Case West and Protoman in Dead Rising 2 Off the Record.
