We've received a report from the infiltration team. They've discovered
a research lab, constructed during the First Terraforming, underneath
Zio Matrix Headquarters.

Zio Matrix headquarters has been retaken, but the Special Forces still
occupy the underground lab. We are requesting that you mop up these
remaining forces.

Disorder units have also been detected in the underground research
lab. Please be advised.



Nell: "The monitor...What’s happening?"

Nell: "Raven, our system is jammed. Communication is not possible. You’ll have to make it on your own..."

Special Forces: "Someone help! It’s moving!"

Special Forces: "Aaaargh!"


This is a rather tricky mission and you can fail this mission if you're not careful. There're many Disorder units throughout the level and although they don't have to be destroyed, they can be quite a nuisance. Should you choose to destroy them, just make sure you have adequate ammo to do so. Otherwise, it's better to just ignore them.

Make your into the deepest section of the facility and you will hear a Special Forces AC calling for help, although it's very much pointless and impossible to rescue him as he dies in the hands of an advanced Disorder unit. This Disorder unit is the same type that is encountered in Save Water Generation Plant. It has same the dual Moonlight-colored blades and spread laser cannon. It is fairly durable so weapons like the Karasawa or any other hard-hitting weapon will work against it. Do note that the area you face it in is rather confined, which makes it much easier for the Disorder unit to hit you, just make sure not to get hit by its blades as that can deal a lot of damage.


  • You get an additional 1500 for each quadruped Disorder unit you destroy.
  • You should equip a head with a bio sensor for this mission.
  • The Special Forces AC unit is destroyed during a cutscene by the bipedal Disorder unit.
