Mass Effect 2

Story related. If you want more info, continue reading. Otherwise, know that this will unlock through the natural progression of the story. You can do this mission at any time after Freedom's Progress. Because the game is open ended, you can complete the mission after completing the game.

The first part of the mission involves destroying the satellite to prevent the VI from been transmitted off the planet. After fighting through some geth, you’ll get to the dish. Climb to the top and then destroy all of the support struts to takedown the dish. Once you’re ready for the next phase, go to the Hammerhead.

In the Hammerhead, there are two stations that you’ll have to take out, Vulcan and Prometheus. Be cautious of the turrets in the area. They’re tough and can do a fair amount of damage if not destroyed quickly. This is the point in the mission that you’ll find the six data packets. Follow the arrows to both of the stations. The number in the lower right will tell you how close you are to each one.

Head to Prometheus Station. There are four shield generators in this area. You’ll have to take down all four while a massive geth cannon is targeting you. Fortunately, it’s easy to avoid once you know what to look for. Stay near each of the shield generators until you get a warning about a geth cannon targeting you. Get outside of the red circle on the ground. This will destroy the shield surrounding the generator, then destroy the generator. Repeat for each other generator. With the shields down, destroy the cannon, exit the Hammerhead, and enter the station. Prometheus, Vulcan, and Atlas Stations are all fairly straightforward.

When you finally reach the core, there are green orbs that are uplink connections. Destroy those and then use what you have to destroy the VI core. Once the core’s armor is depleted, then you get to decide how the DLC ends.
