The Army of Faith broke into the Hologen research facility at Mt. Threshold. Trapped inside are the building's late working scientists and graduate students. The suspects have released a statement declaring their willingness to become martyrs.
Objectives: Bring order to chaos. Rescue all of the civilians. Rescue Dr. Theodore Sturgeon. Neutralize Jean Trouffant. Secure the briefcase.
Loadout: Armored suspects fill the research center. Equip full metal jacket ammo if you plan to use lethal firearms. Load the team up with a mix of flashbangs, stinger, and gas grenades. You should take four door wedges if you follow this walkthrough to prevent suspects surprising your team from the rear flank. Arm each team with an optiwand.
Choose between two possible entry points: the main lobby on the first floor or a second floor side entrance. Choose the main lobby. You can clear the main lobby and use a wedge on the double doors that lead to the rest of the first floor then you can search the second floor completely before returning to complete the lower level. Search the main lobby for incapacitated hostages. There are many throughout the research center.
Ascend the staircase to the second floor of the lobby. There are two doors: a set of double doors on the left and a single door to its right. Use a wedge on the double doors and order a team to check the single door with an optiwand. This door leads into the computer analysis room.
The computer analysis room contains some side alcoves that suspects can use to avoid the gas or flashbang. Toss in either and shout to try and root suspects from their hiding spot. You may want to use a second grenade to encourage any suspects within to submit to your team's authority.
The lobby provides access to both floors…and it's usually deserted.
Find the exit door on the far left corner of the room. Check the door with an optiwand to see if the hall contains suspects. The hall beyond features a set of double doors on the left and a single door found to the right. Order a team to stack up or cover the double doors (or you could use a wedge) and check the door on the right that leads into wetbench analysis.
Toss a gas grenade or flashbang into the wetbench analysis room before sending the team inside. Cross the room to the far left to find the exit door. Check the hall beyond with the optiwand. The hall contains a door on the right (the other entry point, which should be checked), double doors to the far left (leads into the same main hall that other double doors do), and a single door to the right of the double doors. Stack up on that door; it leads into the clean room.
Check the door with an optiwand but realize there could very well be suspects inside regardless. Once inside the room, beware of a hiding spot on the right as you enter. Toss a flashbang there if you're cautious. Reach the end of the room and find a door on the left and right sides of the room. The left door returns to the main hall so stack up on the right door. Check it with an optiwand. It's the cryogenics room.
A suspect can hide behind the pillar in the back of the room. Even if the team reports no one inside, be very cautious upon entering the room. Toss a stinger just past the pillar. Open the door on the right side of the room to find the stairwell to the first floor. Start down once you're sure you've cleared the entire floor. You can see the lower cryogenics room from the stairs. Toss a gas grenade into the room below before descending the staircase fully.
Use teams to cover or wedge particular routes as you begin to clear a path through other rooms.
Check the door that leads into the first floor clean room. Toss a gas grenade inside. The room stretches across to the left side so you may want to use a second grenade (such as a stinger) to cover that side.
Approach the clean room exit. Use the optiwand to check the hall. Exit and wedge the double doors on the right if possible. There are two doors into the same central workstation area. Order a team to stack up on each door. Order both teams to bang and clear (or toss in your own grenade manually to aid one team).
Find the door in the back right of the central workstation. Check with the optiwand before exiting. The set of double doors to the right connects to the main hallway; if you still have a door wedge, use it. Approach the single door on the opposite wall. Check using the optiwand. The door leads into the animal research area.
There are three doors inside this room. Order one team to stack up on the middle door and then take the other team through the door to the far left. Check with the optiwand and toss in a flashbang if necessary. Watch the door in the back right corner of this room; if it's open, suspects might come in or could spot you when you move close. Order the second team to stack on this door. Now order both teams to gas or flashbang the room and clear. The room is multilevel; each door leads to its own level and they're fairly separate.
Move to the door in the back right corner and check the final room on the floor using the optiwand. Use remaining grenades to clear the room and subdue any suspects inside. The mission ends once you have subdued suspects, neutralized Jean Trouffant (the suspect without the mask), rescued hostages, and found Dr. Theodore Sturgeon and his briefcase.
