It would be great with fun weapons, not any real weapons but some crazy stuff. Soem weapons in the good ol build based games were totally brilliant. Duke 3d: Shrinker, Microwave Expander, Devastator, Freezer and feature that you could kick with both feet at the same time. Shadow warrior: The monster head that shoot flame, nuke(!). You know, things like that.
Oh.. and great maps also..
