So tonight I decided to replay a few of my favorite Halo 2 campaign missions, and I noticed that all the preorder exclusive skulls were unlocked so I slapped all of the physics altering ones (and IWHBYD for good measure) on and jumped in.
Holy hell, Sputnik, boom, and feather gives Halo 2 cartoon physics. I juggled an enemy Spectre around for minutes before my banshee bomb blew it up. Even the tiniest explosion will send a Ghost into the stratosphere. It's the most hilarious fun I've ever had in Halo 2.
Also I looked at an Elite and he told me to make him a sandwich.
