The Gate A and Gate B elevators will lock with bulkheads and the elevators will be disabled. Once the timer reaches zero, the facility will detonate. MTF will not spawn during the countdown, if a spawn helicopter comes it will simply hover over the ground until the facility detonates or the detonation is cancelled. All doors (Excluding the Alpha Warhead Control room, SCP-106's and SCP-079's chambers) will be opened. Once the button is pressed, a 90-second timer (Default, servers can change the amount of time) will commence with an announcement, a continuously sounding siren, and all lighting in and outside the facility will become red. Next, a keycard with the Alpha Warhead privilege must be found to open the door to the Alpha Warhead Control Room on the Surface Zone and unlock the button to the Alpha Warhead Control Panel found inside. In order to detonate it, the Remote Detonation switch in the Alpha Warhead room must be switched to 'ON'.
When detonated, the Alpha Warhead removes access to and kills all players within the Light Containment Zone, Heavy Containment Zone and Entrance Zone.
