Heading away from the Green armor past the teleporter, another corridor leads back to the center but at ground level. High upon the ledge the Grenade launcher resides. Ignoring a second teleporter and the secret entrance of the Ligtning gun, a small passage leads to the room with the Rocket launcher and the Red armor. Another hallway at ground level ends up in the central area once again. Jumping into the tunnel across, the small room with the Megahealth and the second Rocket launcher is discovered.
