Dishonored

First-person assassin combat with sword, crossbow, pistol and gadgets against human guards; blood sprays and drop/melee kills can decapitate or cut enemies, so bloody killing is a core option.

Alcohol is served and consumed, characters drink and get drunk, and lore references addictive elixirs and drug dens.

The story centers on assassination, a citywide plague, orphaned and endangered children, betrayal, and streets littered with corpses.

The player is an assassin who commits murder, burglary, and trespass across missions.

Corvo is imprisoned and branded, and interrogation and grim punishments (including a target having his tongue removed) are part of the story.

The Golden Cat is a functioning brothel shown in a mission, with courtesans and paid sexual services depicted.

Enemies can be decapitated in combat, and corpses can be dismembered or consumed by rat swarms.

A high-end bathhouse setting involves paid courtesans, with suggestive dialogue and innuendo about the services on offer.

Occasional profanity in NPC dialogue and audio logs.

Courtesans and bathhouse patrons appear in revealing attire in the Golden Cat pleasure house.

Plague-infected 'weepers' shamble through the streets and swarms of rats devour bodies, creating a grim, unsettling atmosphere.

A supernatural being called the Outsider grants a branded mark and magic; shrines, runes, and bone charms are treated as heretical in the world.

Rats and fish can be killed or possessed as a stealth/combat mechanic.
