Around Heavy Containment Zone are 5 Emergency Power Stations. There are 10 possible rooms they can spawn in. They require a keycard with to unlock them. Once they are unlocked they can be opened or closed by anyone. A Weapon Manager Tablet must be placed in the Emergency Power Station to boot it up. When a tablet is placed, SCP-079 is alerted via pop-up. The room will then be marked red on his map, allowing him to tell SCPs where they are. Anyone can cancel the boot-up sequence by pressing E on the red button. If the tablet is left in for about a minute, the Emergency Power Station will turn on and C.A.S.S.I.E. will announce it.
Once all 5 are turned on, Heavy Containment Zone will Overcharge in 1 minute. When Overcharge happens, Heavy Containment Zone blacks out, all doors will close and can not be opened. If there is an SCP-079 present, he will take 1,000,001 damage, killing him instantly. After about 10 seconds, power will return to normal in Heavy Containment Zone.
Overcharge will not happen while the Alpha Warhead is going off. Killing SCP-079 with Overcharge will give the MTF 4 Respawn Tickets.
Due to the fact Overcharge closes doors, it can cause people to get trap in a room with an SCP.
If SCP-079 is the last SCP, the Overcharge process will be forced to happen in 1 minute.
Text-Based Remote Admin
Using Text-Based Remote Admin, one can force an Overcharge in Heavy Containment Zone with the overcharge command. The parameters are as follow: overcharge <duration> <onlyHeavy>. The <onlyHeavy> parameter will cause the blackout to happen in Light Containment Zone if set to false. Forcing an Overcharge with Remote Admin does not kill SCP-079, and is simply only used to blackout Heavy Containment Zone and Light Containment Zone, making this command useful for server events.
