Here's an E3 2016 trailer from Vampyr, the upcoming vampire gaym from DontNod coming next year to Windows and consoles. The clip is accompanied by a description of the moral and practical decisions this game will involve:

Vampyr, the new Action-RPG from acclaimed game-development studio Dontnod, explores protagonist Jonathan Reid's moral plight in the E3 trailer. Set in London, 1918, Vampyr promises to offer a unique and deeply immersive experience with a strong and engaging narrative steeped in vampire mythology. The E3 trailer unveiled today introduces the nightmare your hero must live every day now he has become a real monster.

You play as a veteran of World War I, Doctor Jonathan Reid as he tries to come to terms with his transition, and the hunger that drives him to kill. Vampyr includes a unique level-up system that plays on this narrative conundrum, where huge amounts of experience points can be gained by feeding on innocent people, compared to combat. As a doctor, you must decide how many lives must be sacrificed in order for you to find a cure for this “disease”, the ultimate goal of Jonathan.

Taking lives in London is not easy. Killing too many in a district may cause its infrastructure to collapse and turn into disarray. Every single life will also have a butterfly effect on the other NPCs surrounding them; a merchant's wife could be killed and he could decide to close shop and leave town. Every life you take away will have consequences for the city and the people around them: Cursed be the choice!
