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.
Improved Clusterfucker alt fire is pretty satisfying!
Also: remember, friends, not even Magnificent Armor can save you from being a complete idiot
