The Purification is where a cleaning protocol will be initiated and everyone must get to a bunker to survive. When this happens, the emergency lights will turn on and the color of the crystals, spikes, puddles will change into a yellow-orange. There are no new exclusive Gootraxians in this event.

There will be an announcement that says the following:

"Attention please, a cleaning protocol has been initiated. Please locate your employee card and make your way to the nearest bunker."

You will have to get a keycard and get to a bunker whilst having to get through lots of people trying to do the same, and there could obviously be fights.
