The magnetohydraulics complex is a location in Big MT in 2281.


The magnetohydraulics complex is an old facility that appears to have constructed robotics. Since its abandonment, a large water main has busted and flooded the facility. It is north of The Think Tank, east of Signal Hills transmitter, and west of both the loading station and waste disintegration platform. There is a corroded trap door leading to a inaccessible lower level.

  • There are various items such as ammunition under water. Having the rebreather greatly aids in retrieving the underwater loot.
  • Beware when swimming under the main structure (above water office room). In the narrowest part of the northeast corner of the room, past a box, the player can get wedged in.
