The Twin Fires Tunnel is a tunnel in the Magmoor Caverns. The room is extremely hot and will damage Samus if she does not have the Varia Suit. The tunnel connects the Transport to Tallon Overworld West to the Twin Fires. Most of the tunnel has a pool of lava at the bottom. The only safe way across is a Spider Ball Track. That leads up from both ends and follows the ceiling. The small side tunnel in the room leads to a dead end. Samus can climb out of the lava if she falls in at the Transport end, but the Twin Fires end is too high to climb out.
