Don't fall off the Catwalk! The amount of ammo on arrival tells you something. "Nathan's Contest". Kill all or don't finish, simple as that, but sure is a fun way to sharpen your kill skills. Total Carnage for the foolishly brave.
A few wall textures have been replaced by lego-looking stuff, and the bobs have been replaced (mostly) by stiff-legged little lego guys (but don't kill 'em, they still use the original bob death sprites). Eh.
We're not programmed to "Save Bob", sorry. Read Me blatant ad for Mr. Trebes. What's that song by Billy Preston, going 'round in circles . . . Maybe Quick Draw McGraw.
