Red Dead Redemption is one of them. I think you can unlock about 6 or 8 with one of them being a Sombrero (shooting someones hat off without killing them). Also Left 4 Dead 2 has some avatar unlockables (my friend has a medical pack he unlocked from the
game). Plus I've heard that Halo reach, Fable III and Dead 2 Rights also have unlockables but I'm not exactly sure what they are. Hope this helps
