Bellum - Overflow Pipes The vent just below the surface of the water opens on an underwater pipe, just large enough for an average Cybertronian to stand upright in. It slopes gradually upward, the water level lowering to about four feet deep after a while. This is likely an overflow system for the Sharkticon Pit. Up ahead, echoing through the pipe, is the sound of rushing water. This becomes apparent as you venture on and come to a junction of three pipes, water pouring from each of them down a long shaft. The roaring of machinery can be heard through the deluge, making down a less-than-appealing option. Metal grates cover the other two pipes, leaving only one viable direction: up the shaft.
