The Maintenance Exosuit (or M.E.S in short) is a suit located beneath the Reactor Management Sector. It can be utilized in shift 3 to move around in microgravity areas, such as the Reactor Chamber or Gravatron. The suit has an integrity variable, which will slowly decrease when entering radioactive areas like the Reactor Chamber. It can be used to move around in the Reactor Chamber, to float up to the METU or perform CBL Maintenance. Once your M.E.S reaches integrity values of about 30%, a warning will appear in the middle of the screen saying: SUIT INTEGRITY CRITICAL, RETURN TO HOME BASE IMMEDIATELY. If this happens, make sure to exit the Reactor Chamber and use an M.E.S Repair Station, of which are multiple located through the facility.
When a gravquake happens, both electrical and mechanical damage will be applied to the suit, forcing it to restart, which can take away crucial time during an Energy Fluctuation Event.
