Objective: Travel to London
This is the only Illuminati faction mission that doesn’t have you return to New York first. Instead, head to London.
Once you emerge from the tube station your mission will update and you’ll get a phone call from the Pyramidion.
Objective: Enter the Mithraeum
Leave the tube station and head north on the road until you get to a small alley on your right.
In the alley you’ll find some stairs down. At the bottom of the doors is the stairs to the Mithreaum.
Objective: Destroy the defence grid power supply
At the bottom of the stairs you’ll get another phone call. Be careful, there are mines everywhere. The mines don’t do a lot of damage but they alert Templars to your position.
Please refer to the following map throughout the rest of the guide.
You need to get the explosives first. Follow the red path to point A.
When you’re right outside of the room with the explosives you’ll get another call from the Pyramidion.
After you grab the explosives, head back the way you came by following the blue path to point B. Make sure you run into the room quickly before the turrets start shooting you. There may be a Templar in this room.
Place a mine on the box on the wall labeled Defence Grid Power Generator.
Objective: Set off the alarm system
Before we set off the alarm we’re going to preemptively clear a path for ourselves later. Follow the green path from point B to point C.
Place a mine on the fuse box and when it explodes, continue along the green path past the turrets that are now disabled. Place a mine on one of the turrets by right clicking on the underground turret to completely destroy them. Now this path is clear. Now it’s time to head to the alarm.
Follow the magenta (purplish) path to point D.
Place a mine on the Alarm System on the wall. Do not wait for it to go off. As soon as it is placed run as fast as you can back to point C. Continue to where you destroyed the turrets. You should encounter a lone Templar agent if you were quick enough (have sprint on before you blow up the alarm).
Objective: Retrieve the Crocea Mars
Once you’ve defeated the lone Templar it’s time to assault the main room.
Because you set off the alarm only two guards remain. Defeat them and take the Crocea Mars from the alcove behind them.
Objective: Escape the Mithraeum with the sword
You can try to be stealthy and make your way back to the exit in any way you choose, or you can simply let yourself be killed. You will respawn next to the door to the outside.
Objective: Bring the Crocea Mars to the Illuminati HQ
Simply return to New York and the Labyrinth.
You’ll get a call from Kirsten Geary and you’ll be promoted to Illuminati Rank 10.
