One of the most fascinating and nuanced storylines inMass Effectis the conflict between the Quarians and the Geth. Their longstanding animosity comes to a head inMass Effect 3when the Quarians launch a surprise attack that causes the Geth to ally with the Reapers.

Despite the centuries of violence, it’s still possible for both races to coexist. However, doing so relies on a complicated set of prerequisites and a hidden points system that factors in decisions fromMass Effect 2. This guide will show how to end the Quarian-Geth War inMass Effect 3andMass Effect: Legendary Edition.

Prerequisites

For peace to be possible inMass Effect 3, players must fulfill all of the following requirements:

The third task is the most difficult, as either can die duringMass Effect 2’s Suicide Mission. However, it’s much easier if Shepard secures the loyalty of both characters. To do so, Shepard first needs to complete both of their Loyalty Missions then resolve the ensuing confrontation. Players will need a Paragon/Renegade score of 70% to earn both character’s loyalty. The player can regain Tali’s loyalty later, but that will make the peace process harder inMass Effect 3.

It’s also a good idea to buy the Heavy Ship Armor, Multi-Core Shielding, and Thanix Cannon upgrades before entering the Omega 4 relay. One character dies for each upgrade not purchased. Different upgrades protect different party members with both Legion and Tali at risk if the Shields fail.

During the Suicide Mission,never assign either character as a squad leader. Only choose one of them as the Tech Specialist if that character is loyal. It’s also a good idea to have Tali escort the Normandy survivors if she’s loyal, but the player doesn’t intend to use her against the final boss. Loyal escorts always survive, and Tali is one of the most vulnerable characters during the last stage of the mission.

Hidden Point System

In addition to the prerequisites,Mass Effect 3uses a hidden point system to determine if peace is possible. The player must earn a minimum of 5 points based on actions inMass Effect 2andMass Effect 3. Players gain points by doing the following:

Priority: Rannoch

The final important choicecomes at the end of the story mission, Priority: Rannoch. Players will need at least a 75% Paragon or Renegade score to unlock the options “Rally the Fleet” or “Warn the Fleet” in the final dialogue wheel. If the player meets all other requirements, choosing either will force an end to the conflict.
