Where do you find the FPS marine map?

Where do you get that map with the marine?
I saw a demo.. YOu can jump and stuff. In first man you can also
see his wepeon.. Where you find that map.?

I think it was under "Arenas" but the link is down. Anyway, as far as I know the map wasn't FPSMod enabled.

As for the weapon you can always see it, but most of the time it's rather interfering so some way is found to take it off the screen.
