TheMass Effecttrilogy is all about choices in that decisions can impact Commander Shepard’s stories down the line, including between games. Players can transfer their save file between games, meaning previous choices such as the fate of certain characters or how certain missions were handled may be referenced inMass Effect2and3.This post contains spoilers forMass Effect 2and3.
But inMass Effect 3, this is especially true because of the war assets leading up to the final battle against the Reapers. How exactly it goes down, and who survives, is determined by a number of factors much like the suicide mission at the end ofMass Effect 2. WhileMass Effect 2influences3heavily, a few factors fromMass Effect 1roll over as well, including who of either Kaidan or Ashley survived on Virmire, if Shepard talked down Wrex, andsparing or killing the Rachni Queenon Noveria. Here’s which decisions carry over toMass Effect 3and impact Shepard’s final mission.

Major Mass Effect Characters and Plot Decisions
The outcome of the suicide mission is one of the most influential factors going intoMass Effect 3. Any squad member can die during the suicide mission, so it’s important to prepare for it. IfGarrus or Tali die, their roles will be filled by other characters. Whether or not the crew survivesMass Effect 2also determines whether or not they appear in the second game. Kelly Chambers will only reappear if Shepard had dinner with her. And selling Legion to Cerberus during the final mission will make him an enemy in the third game.
Shepard must choose tosave either Samara or Morinthduring Samara’s loyalty mission. Whoever they saved with show up inMass Effect 3; Samara will help Shepard during a mission but Morinth will simply send an email. And during Mordin’s loyalty mission, Shepard must decide whether to destroy the genophage research data or to keep it, which has consequences for the Krogan named Eve.

Several characters can be romanced inMass Effect 2. Any romances fromMass Effect 1 —Liara, Kaidan, and Ashley— can be preserved for the third game. Unlike Kaidan and Ashley, players can reaffirm their romantic relationship with Liara duringLair of the Shadow Broker, but if Shepard chose to romance someone else after starting a relationship with her, she will mention this duringMass Effect 3. Anyone who was a squadmate inMass Effect 2can only be romanced in3if continuing that relationship from the second game. This includes Jack, Miranda, Tali, Thane, and Garrus.
Finally, destroying the Collector Base during the suicide mission will award Shepard with the Reaper Heart war asset, while preserving it will award the Commander with the Reaper Brain war asset.

Other Plot Decisions in Mass Effect 2
Smaller decision inMass Effect 2that will be referenced duringMass Effect 3or influence the course of the game includes choosing whether or not to be reinstated as a Spectre, punching the journalist Khalisah al-Jilani at the Citadel, and completing theDLCsOverlord,Lair of the Shadow Broker,Firewalker,andArrival.Completing those DLC packs adds unique dialogue but will otherwise not have any impact on Shepard’s war assets as completing the DLC was not required in the original trilogy.
During another DLC that introduces the thief squadmates Kasumi, Shepard will decide whether or not she keeps or destroys Keiji Okuda’s graybox. During Tali’s loyalty mission, there’s a chance she will become exiled. If this happens,peace between the Quarians and the Gethwill be more difficult to achieve. This task will also be impossible if Legion or Tali die duringMass Effect 2’s suicide mission.
