The Steambot Barracks is a room on SkyTown, Elysia. It appears in Metroid Prime 3: Corruption. The room is a hibernation chamber for one of the Steamlords of SkyTown, and it also houses several of its dormant Steambot drones as well.

The room is a medium-sized chamber with two levels. There are six Elysian recharge chambers around the ground floor of the room, where Steambots reside during regeneration cycles. If an intruder presence is detected, the room will be sealed and the Steambots will be deployed from these units to attack. A large metal containment device is present in the centre of the room. The Steamlord is present within, and will also be awoken in the event of enemy intrusion. The containment device will retract into the floor, and a small pod will be launched into the air, from which the Steamlord will be released. Notably this pod is similar to an Elysian satellite, and will continue its ascent after the Steamlord has left it. Before the Steamlord emerges, noises can be heard from inside it. It is likely that the Steamlord made these noises, although the chamber itself might have been the source.

Near the top of the room is an elevator which will descend into a mid way point in the room. Here, a small hatch can be entered that leads into a maintenence tunnel network, where two small pistons are present. These appear to be for the purpose of energy generation, but one is malfunctioning. This network eventually leads out into the ground floor through an opening in an empty Elysian Recharge Chamber. However, to the right of the elevator is a hatch that will lead onto a ledge. From here, one can jump down into the main section of the room where the Steambots are present. This hatch, however, can only be opened from the ledge-side via interaction with a small terminal.

The exit to this room can be sealed off, by use of a pressurised gas system, which when activated will release two metal gates to slam shut to block the door. This gas system is regulated in safety release valves in each of the six Recharge Chambers. Destroying the valves will release the pressure to the gates, and they will retract. These valves are resilient to Beam attack, but can be ruptured by a strong kinetic force.

The fully-assembled Half-pipe.[2]

Finally, a circular kinetic energy converter is present in the far wall of the ground floor. This panel has a small opening, which allows the insertion of a metallic sphere. If the sphere collects enough speed inside the panel, this will allow the kinetic energy to be converted into electrical energy. This will raise a small metal device from the centre of the room, which will then expand to create a makeshift Half-pipe. This Half-pipe can be ascended to reach a ledge to connect the ground floor to the midway point of the room.


Samus arrives in this room during her exploration of SkyTown. Samus enters at the top of the room, and after activating a Hand Scanner, she takes the lift down to the mid-way point. Here, she enters the tunnels in her Morph Ball. Inside there are multiple obstructions, although Samus can destroy these with her Bombs. Two pistons block the upper shaft, but will cycle between pumping up and down, supposedly for energy production.

One of these is malfunctioning, however, and remains locked out of the way. Samus emerges from the tunnels through a hole in the top of an inactive Recharge Chamber. Samus attempts to leave the room from here, but is denied authorisation and locked out. Samus swings around to see the Steamlord and five Steambots awaken from cryostasis. Samus engages them, and is successful in destroying the Steamlord, which severs his link with the remaining Steambots. Samus then uses her Grapple Lasso to breach the release valves that hold the gates in place over the exit door. Samus then leaves the room.

The Steambots are deployed.

Samus later returns here after acquiring the Boost Ball. Samus now uses the kinetic energy generator at the back of the room. She enters using her Morph Ball, and continuosly Boosts around inside to generate enough electricity. After anough energy has been accumulated, a small pole is raised from the centre of the room. This pole quickly expands into a Half-pipe formation, which Samus uses to reach a ledge at the mid-way section of the room. Samus then uses her Arm Cannon to remove a Combination Lock blocking access to the elevator, thus reconnecting the two parts of the room.
