Excessive Unreal 2 is one of the most chaotic, stupid, hilarious, and insane mods ever made for Unreal Tournament, and it has incredibly well-balanced, action-packed gameplay. If you like Serious Sam, Doom, and Unreal - especially when blended together in the most absurd (yet somehow perfect) way - this mod is for you.
This is a brief demonstration of the Shitgun exclusively. I figured someone might want to see this since the Weapon Montage doesn't do the best job of showing off its features and effects, and it's been updated a bit since then.
