A subtrope of Multiple Endings, where said endings can be mapped onto the Good vs. Evil, Order Versus Chaos, occasionally Neutrality, or some other form of Character Alignment. Which ending you get is usually either based on your Karma Meter standing at the end of the game, or follows from a Last-Second Ending Choice.
Rule of thumb to tell if an instance of Multiple Endings falls under this subtrope is to check whether they are mainly referred to as "Good/Evil/Neutral Ending", etc.
- In Dark Forces 2: Jedi Knight, the ending is determined by a hidden Karma Meter. In Jedi Academy, you instead explicitly choose your side in the penultimate story mission.
- In Knights of the Old Republic, the player is free to choose the ending, although the ultimate decision takes place shortly before The Very Definitely Final Dungeon. In the sequel, by contrast, the ending you get depends on your alignment in the endgame.
- Both The Force Unleashed and its sequel feature Light and Dark side endings.
- The class-specific campaigns in Star Wars: The Old Republic are mostly linear, but the player's moral choices alter them cosmetically. Also, while the Light Side path is canon for Republic characters, the Dark Side is this for the Empire classes, e.g. the Sith Inquisitor is referred as Darth Nox (a Dark Side title) rather than Darth Imperius (Light Side) in the later canon materials. The last is unprecedented: in every single previous game where there has been a choice between the Dark Side and the Light Side, the Light Side has been established as the canon choice.
- In inFAMOUS, Cole's actions affect the story's endings. He can either be good, or he can be evil. The choices are rather obvious as to whether they're good or evil, though.
- Enclave features two campaigns, Light and Dark, and accordingly a good and an evil ending.
- Shadow the Hedgehog has ten possible endings, with Pure Dark, Pure Neutral, Pure Hero, and True Ending as the main four, plus an Omega Ending for getting all ten. And, for some reason, the game keeps track of all 326 possible paths to reach those endings.
- In the Tex Murphy game The Pandora Directive, you can get up to eight different endings depending on where your Karma Meter is along the Nice Guy/Jerkass axis.
- In Gabriel Knight: Sins of the Fathers, Gabriel can choose at the end whether to try to save the possessed Malia from the pit she's dangling over, simply let her fall to let Tetelo die, or try to actively kill her to achieve the same.
- There's a bunch of endings in an adventure game the white chamber based on the main heroine's (and therefore player's) attempts to act good and to redeem her sins, none of which actually affect the gameplay otherwise.
- In Bioshock, you get different endings depending on how many Little Sisters you killed, if at all.
- In Oddworld: Abe's Oddysee and its two sequels Abe's Exoddus and Munch's Oddysee, the final cutscene is determined by the number of slaves (test subjects in Munch's Oddysee) you rescue throughout the game. You have to rescue enough to get the good ending, otherwise you get a surprisingly dark bad ending.
- Baldur's Gate II: Throne of Bhaal has three endings: Good God, Evil God, and Mortal.
- Neverwinter Nights 2 has the canonical good ending where the Knight-Captain and Player Party defeat the King of Shadows. The non-canon evil ending has the Knight-Captain pull a FaceHeel Turn and join the King of Shadows after killing the party. The Expansion Pack Mask of the Betrayer has several variations on its endings.
- In Fallout: New Vegas, the ending depends on your Karma Meter and on which side you take: the NCR (a democratic but corrupted government), Caesar's Legion (a dictatorship based on Rome who use slavery and violence), Mr. House (a dictator who wants to restore Vegas past glory but don't care about anything else) , or the chaos ending (where you basically reject the three latter faction to ensure New Vegas freedom by yourself).
- While the ending of Deus Ex: Human Revolution is mainly determined by the Last-Second Ending Choice of who wins the information war, the tone of Jensen's final narration that shows his Character Development depends mainly on how many people you've killed and how helpful you were to others throughout the game.
- GoldenLand (a.k.a. Heath: The Unchosen Path) has two endings, Good and Evil, depending on whether you decide to fight the Big Bad Drakh Shu or the Big Good Belobog in the Final Battle.
- In Mass Effect, depending on whether you were a Paragon or Renegade and whether or not you saved the Council, the ending speech Captain Anderson or Ambassador Udina gives will differ. The Paragon ending has a Rousing Speech basically along the lines of "We will rebuild, and we will fight side-by-side." As a Renegade, the speech consists of how humanity will protect the galaxy at any cost.
- The two sequels follow similar patterns, though the third one has a lot more variables since it factors decisions from all three games.
- The full 3D editions of Spider-Man: Web of Shadows has four endings, determined first by your alignment but only when the sonic bomb is reached, then by whether or not you used the symbiote to heal Black Cat
- Undertale has one Pacifist ending (everyone in the game survives one way or another and the barrier is destroyed, allowing monsters to leave the underground and reintegrate into human society), which you see if you kill absolutely nobody; one Genocide ending (the Fallen Child kills everyone in the underground and, with or without the player's assistance, destroys the entire game world), which you see if you kill absolutely everybody; and several different Neutral endings (the monsters remain underground and mostly lose hope for escape due to the disappearance of the human souls; who takes up the throne after Asgore's death depends on which bosses, if any, were killed), which vary depending on how many monsters you've killed.
- Dawn of War II Chaos Rising has multiple endings depending on the corruption of your squads (which fills in for the Karma Meter in the game) as well as several choices you make over the plot of the story. They range from your Commander replacing Davian Thule as captain of the Fourth Company and helping Gabriel Angelos and Apollo Diomedes cleanse the Blood Ravens of corruption to your Commander fleeing with your squads into the Eye of Terror and joining the Black Legion.
- Republic: The Revolution has three endings, one of each of its dominant ideologies: in the Force ending, you launch a Military Coup to take over Novistrana; on the Influence path, you start a Velvet Revolution instead; and with Wealth, you simply force the President for Life to resign by crashing the economy and putting the blame on him. There are no elections in the game, by design.
- Dishonored uses a system called Chaos; High Chaos is caused by killing every enemy in sight, while Low Chaos is caused by using Non-Lethal K.O.s against guards and finding alternative ways of disposing of your assassination targets. There's also a hidden "Medium Chaos" ending in the middle. You get quite a few hints along the way: the princess's attitude remains light or becomes dark to match Corvo, and before the final mission, Samuel the boatman's attitude towards you when he says goodbye reveals the ending you're getting. In Low Chaos, he says It Has Been an Honor; in Medium, he accuses you of killing needlessly and says he never wants to see you again, and in High, he actively alerts the enemies to your presence.
- In Red Dead Redemption II, your honor slightly changes the final cutscene. While Arthur Morgan's death warrant is already signed with his tuberculosis, a high honor results in Morgan being left to die somewhat peacefully watching the sunrise, while a low honor results in Micah finishing him off. The former is considered as the canon ending.
