Half-naked guy

In the final level "Halo," there is a secret area for the 7th Marathon Terminal (see Marathon Terminals Page). Aside from the terminal's hallway, there are two rooms: one bright room with a vertical energy beam in the center, and a dark room with a horizontal energy beam and lethal chasm.

It's hard to tell by standing at the edge of the chasm, but there is a small nook on the left side of the room (left, as if one looks out over the chasm). It is not known whether a player can rocket/grenade jump there, but by watching a save film, one can detatch the camera and move in there.

In the far corner of the nook is an eerie billboard of a human form facing the wall, apparently with its hands behind its head. Or you could rocket jump up the wall and enter the crack. Turn on your flashlight and you will hit a abyss. across from that is a floating man wearing green boxwers with his hands over his head. If you make it across he can not be killed and has a very strange face
