Mission Summary[]

This mission request involves destroying the Triton Research Center.

Activate the Facility's backup generators to enable the self-destruct mechanism to engage.

Ed Weisz


Raven, we've just learned of some potentially deadly research that was being carried out in secret at one of our facilities.

Given how unstable things are right now, we feel it prudent to destroy all of the evidence.

The facility must be leveled.

Unfortunately, power shortages are preventing the self-destruct mechanism from engaging.

We need you to activate the backup generators. Exit the facility as soon as this has been accomplished.


  • MT x3
  • Evolved Amita x3
  • Mumu


The following information is "gray area" content — it may not be completely factual, and/or falls under YMMV territory.

The facility itself is very straightforward in the beginning, simply continue on as you eliminate the MTs blocking the way, because this area is very tight. Reaching the end of the straightforward hallways, the Raven will drop down to an octagonal room after taking an elevator.

The gates in this room are elevated, so eliminating the three Aimta in the room will be most helpful in clearing smoothly. In relation to where the Raven drops: Southwest leads to one generator, upon approach, an opening will appear in the floor on the way back to the octagonal room leading nowhere. Southeast leads to the same situation. The Northeast gate reveals the same situation as the other two. Upon activating the other three generators, the Northwest gate will unlock itself.

After activating the last generator, a cutscene will reveal an ambush by a pilot named Mumu. She will be waiting in the octagonal room for the Raven, and the time constraint for escaping is marked as 3 minutes.

Mumu's AC is a middleweight, she'll back up as far as possible at first, leaving herself open for the Raven. Getting close is ill advised, because she has a parrying blade and will inflict major damage. From far away, she'll simply throw rockets at you, these can be avoided and/or destroyed very easily because she only shoots one at a time. 

Any AC with a high damage weapon can defeat her, should they choose to. The Raven has no obligation to fight her, and can simply make their way to the escape point once the timer starts. One way or the other, she dies.
