Project Overlord

There is something strange going on at Aite in the Typhon system within the Phoenix Massing cluster. A rogue VI has taken over the Cerberus facility, shutting down and rerouting the base's systems. Head inside the base and you'll be briefed by Dr. Archer about the situation: You'll need to disable the radar dish's antenna. Head across the tram and enter the next building.

You'll come under fire from a large number of Geth controlled by the rogue VI. These include Troopers, Destroyers and Rocket Troopers. Make sure to keep far back and in cover, as a second wave of Geth will enter after the first is cleared. Move further and you'll exit out to some broken catwalks. Move across cautiously and take out the mechs on the other side.

Enter the lower section of the dish and be ready to take on the swarm of Geth, lead by a deadly Geth Prime. Afterwards, ascend to the top of the dish and blow out the capacitors. There will be a large amount of Geth guarding these fuel tanks, but your squad will provide ample distraction while you access the terminals and destroy the tanks.

Afterwards, you'll meet face-to-face with Archer, and he'll inform you that in order to disable the VI you'll have to unlock the overrides at the Vulcan and Prometheus stations, followed by entering the Atlas Station. The first two can be done in either order. You'll be piloting the Hammerhead and will be traveling over a grassy plane. If you encounter enemy fire on the way to each station, be sure to stop and take out the cannons or troops.

Vulcan Station

Vulcan Station will require a lot of platform jumping and dodging with the Hammerhead. You'll need to leap across various rock formations that are floating in the lava rivers. Move quickly though, as the rock will sink shortly after landing on them. The lava will do minor damage each second, which can pile up fast if you spend too much time in the heat.

You'll come to an outpost where you'll need to access the steam vents to ascend to higher levels. Destroy the few LOKI Mechs and then access the terminal. Return to the outside, use the steam to propel up the mountain and continue moving up the lava river. Enter the main facility of the Vulcan station and you'll be attacked by LOKI guards. Deeper in there will also be Assault drones and even a powerful YMIR. As always, concentrate fire on the large YMIR Mech while your squad takes care of the smaller enemies.

You'll eventually come to the control station to remove the lockdown on Atlas. There will be a lone LOKI inside and you'll have the chance to destroy it with a Renegade interrupt.

Prometheus Station

The station is actually a crashed Geth ship that is under research. The rogue VI has taken control of the ship's main cannon and erected shields around the generators. A single blast from this main gun can rip through the Hammerhead, destroying it easily or leaving it heavily damaged. You'll actually need to trick the VI into destroy the generator shielding by moving towards these targets. The cannon will charge up and fire, quickly move out of the way and the VI will take down the shielding in its assault.

Use the Hammerheads Missles to take down the unshielded generators one at a time. Repeat the process and the main gun will be vulnerable. It can still do the same amount of damage to you, so keep moving and destroy it once entering a clear shot.

As expected, there is a huge amount of Geth inside the station itself, including a Geth Prime in the center of the ship. Your goal is to make it to the lockdown override near the other side. You'll need to mover several platforms to create a path to the other side. Simply move the middle and left pieces so they align and form a bridge. You can also create other formations to find various items scattered aroudn the ship.

After releasing the lockdown, the Geth will all activate, including powerful Troopers, Hunters, and even a few Destroyers. Move slowly through cover and use any abilities to take out armor. As you attempt to exit you'll also be attacked by the Prim from earlier. Take out the smaller enemies or left your crew deal with them. The Prime itself is the most dangerous, so you will want to minimize other distractions.

Atlas Station

After clearing both Vulcan and Prometheus, you'll have access to the Atlas station. You'll fight through a few Geth Troopers, but will soon enter the VI's world. Shepard's Omni-tool will go haywire and you'll lose acess to the rest of your team.

As you make it through the strange computer area, you'll learn that the rogue VI is actually a human strapped into a machine. The VI is revealed to be David, Dr Archer's brother. David will release more Geth on you, which are fairly easy for a solo fight.

You'll soon encounter David directly. Shoot the VI control nodes that move through the cable, followed by shooting the core with heavy weapons. Every so often more Geth will come to assist, so take the time to clear them out. If David manages to upload his VI the mission will fail, so be sure to destroy the machine fast.

Afterwards you'll have a Paragon or Renegade choice to decide David's fate.
