Mass Effect 3 Guide › Walkthrough › Act 2

Act 2 – Priority: Rannoch

The geth remain under Reaper control, thanks to a base located somewhere on the surface of Rannoch. Continue to help the quarian fleet survive the geth attack until the Reaper base can be located.

MISSION BRIEFING

Battlegrounds: No matter where you engage in battle during this mission, EDI and Tali will prove to be your best weapons. Tali must come along, forcing you to decide on the third squad member. Bring EDI, and her Decoy ability will prove very useful in nearly every encounter.

The geth facility is comprised of a series of walkways, many of them with great spots for cover. However, like the geth Dreadnought, the structure isn’t overly complex or spacious. The machine’s gift of efficiency allows them to utilize small walkways without the need for wide, open spaces.

Adept players will enjoy being able to combine powers in tight spaces, while snipers and Engineers can safely engage enemies from across long walkways.

Ashley’s disruptor ammo allows her to rip through enemy shields and can help the whole squad if she has the squad ammo upgrade. With Tali present to remove geth shields, Liara provides excellent crowd control with her Singularity power and can take down armored enemies with Warp.

NOTE

If you imported a save where Tali is not available, then you can select any other two squad members for this mission.

Consequence Overview: There aren’t many options for Paragon/Renegade points during the mission; however, after the final battle, you’ll be faced with a major decision that not only grants you Paragon/Renegade points, but also decides which new fleet you’ll be bringing into the war.

WAR PREPARATIONS

As the war heats up, things around the Normandy and the Citadel begin to cool down. There are no new missions to pick up, so feel free to either turn in any side missions you’ve completed to the Citadel or travel across the galaxy to complete missions before it’s too late. If you completed only one of the two previous missions, you can take this time to complete the second. Once you begin this mission, the other one disappears.

If you’d like to get straight to the next mission, skip to the “Reaper Base” section later in this guide.

ABOARD THE NORMANDY

Tali and Admiral Xen are in the midst of a fierce disagreement in the war room. Listen to what they’re talking about and either support Tali or the Admiral. If you support Tali, you’ll gain Paragon points. Support Admiral Xen for Renegade points.

UPGRADE WEAPONS

Now is another good time to invest in weapon upgrades. Many of the upcoming battles will be against multiple types of enemies at once, such as geth Hunters, geth Rocket Troopers, and geth Prime, so upgrade any new weapons that you have taken a liking to. Weapons like the Arc Pistol, which is specifically designed to be used against artificial life-forms, will be of great help.

REASSIGN POWERS

If you’ve already reassigned your powers once for free, reassigning your powers again will cost you only 5,000 credits. It is well worth it if you’ve invested points in powers you don’t frequently use. Spend the credits now and reassign your powers so that you maximize the value out of every point.
