Dishonored

The game creates characters to which you become emotionally attached, particularly the heir to the throne, a little girl named Emily, who the hero Corvo aims to protect. Players are always given a choice whether to kill a target or eliminate them through non-lethal means. While there is betrayal and ruthless killing by some characters, the heart of the story is about honor and its meaning to the individual. 

Players have the option to finish the game without killing any other character, though most are unlikely to achieve this, given its difficulty. When they do engage in combat, it's bloody, with severed limbs and bloody stains. Players use pistols, crossbows, swords, grenades, and other weapons to kill human enemies. Those kills are sometimes accompanied by slow-motion effects and gurgling sounds. Corpses are often devoured by packs of plague-infested rats. And there are corpses strewn around this plague-ridden town. 

Plenty of salty language, including "damn" and "hell". “F--k,” “s--t,” and “a--hole” are also used regularly. 

Many scenes take place in a bar and several characters openly consume beer or other spirits. The player's character also drinks on occasion -- and players can choose to drink more as they explore the world.
