I know we all definately dont have this.

Anyways, on the wikipedia page it mentions

"Additionally, a few more (clearly unfinished) levels were bundled with the Alpha that cannot accessed without first enabling the console and loading them manually. Often these levels are so unfinished that they cannot even be played at all, only viewed through UnrealEd. These maps include unfinished Battle arenas, Level Select hub-worlds, maps that might have possibly been used for cutscenes, and even a playable (but unfinished) singleplayer map originally seen in Jazz Jackrabbit 3 concept art (involving a cliff-side waterfall, a giant mine shaft, and undersea ruins).
"
Anybody actually know how to load these maps from the console?

Second. I am interested to know about how many levels there actually are, and what they are.
