Ruglen lab is under attack by life forms of unknown origin. Immediate backup is requested.

We've tried to clear them out ourselves, but our weapons haven't had any noticeable effect.

All means of access are sealed, so their numbers shouldn't increase. Now we just have to figure out a way to deal with the ones already inside.

Our researchers are analyzing them for any weaknesses, we'll notify you once we know.



Laine Meyers:Numerous targets careful in there.

Laine Meyers:Crest’s researchers indicate that the life forms are susceptible to acid. They’re going to deploy canisters filled with an acidic gas. Break the canisters to release the gas and weaken the life forms.

Lab Announcement:Opening ceiling storage bays. Deploying canisters. All personnel, please stand by.

Laine Meyers:All targets destroyed. Return to base.




You should at least use a head with a bio sensor for this mission, if not also a back radar with a bio sensor.

This mission can be easy or hard depending on whether or not you want to get the hidden part. The Life Forms can be killed without it, but it's only feasible with the MOONLIGHT with a tank or quad for the "poke of death." Otherwise, simply boost to the roof and land on one of the gantries above the room. The bio weapons won't attack you there and you can simply await for the acid containers to be deployed. After destroying them, the life forms become much more vulnerable to conventional weapons and you won't waste your ammo trying to kill them.

S-ranking this mission isn't difficult at all. Wait in the first room for the canisters to deploy, then quickly destroy all the containers in the whole facility, then turn around and destroy all the life forms. You're given a generous amount of time.


  • The CEEC-01-XSP2 Extension part can be unlocked during this mission. To unlock the part, kill all of the enemy life forms using only 2 acid containers or less.
