YMMV / Mass Effect: Annihilation

• Crowning Moment of Heartwarming: In its own way, the simple fact the Keelah Si'yah has batarians on the crew at all. The batarians are nigh-universally despised, thanks to the Hegemony, even more so than the geth, but the Initiative lets them have a chance at a fresh start as well.
• Moral Event Horizon: Captain Qetsi cooking up a virus that can jump across species, to wipe out a large amount of humans, turians, asari and salarians just to put the quarians on top. And worse, she's so insane she doesn't think that her actions are at all monstrous.
• Squick: The descriptions of what the virus can do get... graphic. Pus, blood, scabs, vomiting and any combination thereof are mentioned in horrible detail.
• Tearjerker: The death of Yorrick. Guy just wanted to play Hamlet. And worse, he knows he's got the virus and what it'll do to him.
