From the water near the hidden Red Armor and below the Quad, a stairway around a lava pool winds down to a button. It is connected to bars blocking the way to a Yellow armor. A quick teleport and the big room can be admired from above. Across a moving platform a Grenade launcher and a Megahealth are available. Jumping down an elevator, the upper Rocket Launcher is within reach. Moving down a corridor reveals the Quad once again. This time at eye level.
