''Mass Effect: Retribution'' is a novel within the ''Franchise/MassEffect'' universe, written by then-lead writer Creator/DrewKarpyshyn.
!!''Mass Effect: Retribution'' provides examples of the following tropes:
* AndIMustScream: One of the main plot elements of the book is Reaper indoctrination.
* BodyHorror: [[spoiler:What happens to Grayson when he's implanted with Reaper tech. The cybernetic implants slowly replace his flesh and the tissue looks like its dying. Anderson even compares him to the [[OurZombiesAreDifferent Husks]].]]
* BoldlyComing: Grayson's relationship with Liselle. He enjoys it so much he even wonders at one point "How can (he) ever go back to humans?"
* {{Bowdlerise}}: A minor example. The narration states that the number one rule of Omega is "Don't cross Aria T'loak". Everyone who's played ''VideoGame/MassEffect2'' will know that her description of the rule is [[PrecisionFStrike a bit more colorful]].
* ContinuityNod: The friendly elcor ambassador from the first game, Calyn, makes a brief appearance while having lunch with Anderson. He's still complaining about the volus ambassador Din Korlak.
* CuffsOffRubWrists: Averted. [[spoiler:Kai Leng is ''bleeding'' by the time he manages to get out of his restraints from where Anderson tied him up.]]
* CuttingOffTheBranches: For the first time in the series (not counting the CanonDiscontinuity of Shepard's second death in ''VideoGame/MassEffect2''), no matter how the player makes it, Anderson in this book is an Admiral while Udina is Councilor.
* DrivenToSuicide: [[spoiler:Subverted. Grayson ''tries'' to do this, [[AndIMustScream but the Reapers won't let him]].]]
* DyingAsYourself: [[spoiler:After Grayson's body is too badly damaged, the Reapers release control and he seems to be this in his final moments.]]
* FakingAmnesia: When a rescue squad recovers a kidnapped character and asks for his name, he is unable to answer and claims that amnesia is the cause. [[spoiler:As it turns out, he, Grayson, has been implanted with alien tech by Cerberus, allowing his body to be remote-controlled by the Reapers. The claim of amnesia was used by the Reapers to avoid the question as they were at that time unable to learn his name by reading his mind. It works horrifyingly well.]]
* FantasticRacism: Kai Leng ''really'' doesn't like aliens. He regards [[WretchedHive Omega]] [[AssociationFallacy as the standard of what an alien-dominated galaxy would be like]] and seems to enjoy killing aliens.
* FightingFromTheInside: Grayson
* GunsAkimbo: Thanks to [[spoiler:his Reaper enhancements, Grayson]] is able to effectively and accurately dual-wield ''assault rifles''.
* HumanoidAbomination: [[spoiler:Grayson]], but not by choice.
* HumorlessAliens: Anderson, while having lunch with Calyn, jokes about attacking Din Korlak (Calyn's office mate, about whom he had been complaining) and "watching the butterball roll out the door". Calyn finds this joke disturbing, and notes that he's unsettled by humanity's sense of humour.
* KarmaHoudini: [[spoiler:Kai Leng]]. Then again, [[spoiler:he appears in ''VideoGame/MassEffect3'' and gunning for [[PlayerCharacter Shepard]]. You ''know'' how that ends...]]
* MauveShirt: [[spoiler:Liselle]]
* MoreThanMindControl: [[spoiler: Part of what makes Reaper indoctrination so effective]].
* NakedPeopleAreFunny: Averted with Grayson, who is naked when [[spoiler:rescued by the turians from the Cereberus facility, especially due to BodyHorror]].
* RagingStiffie: Happens to poor [[spoiler:Nick]] not thirty pages into the book, who probably advances [[HotForTeacher one trope]] and narrowly subverts [[JizzedInMyPants another]] while he's at it.
* StuffedIntoTheFridge: [[spoiler:Liselle is murdered by Kai Leng in order to cast suspicion upon Grayson. Considering that she was Aria's daughter, Aria is pissed when she arrives at the crime scene.]]
* SadisticChoice: [[spoiler:Kai Leng]] gives [[spoiler:Anderson]] the choice of either [[spoiler:arresting him]] or [[spoiler:letting the fifteen-year-old Nick die from a gunshot wound to the stomach. Anderson tries to [[TakeAThirdOption Take a Third Option]] by shooting Leng in both legs then going to help Nick, but Leng barely escapes]].
* TokenRomance: Subverting the one in ''Literature/MassEffectRevelation''; Kahlee and Anderson are still close despite not having worked together after twenty-one years.
* TragicMonster: Grayson
