10 Video Games That Reward You For Killing NPCs

10. Vampyr - Part Of The Problem

It must be a moral quandary, being a vampire doctor. That is, a doctor who is also a vampire. Not a doctor to bloodsuckers, to clarify.

Jonathan Reid, a doctor during the Spanish Flu-era of London, comes back from the Great War to find himself turned into a vampire. And kills his sister, the silly sod.

The long and short of being a vampire is that they need sustenance: of the iron-filled, claret-coloured kind. To wit, they need blood to function.

But Reid is a doctor, and amongst other treatments, he's meant to keep people's blood inside of them. It's a doozy of a quandary for a man with a Hippocratic Oath.

Of course, players can resist the urges and stay mostly human throughout the game. It nets some good morality points, but is certainly harder than giving in to temptation, and levelling up.

If you do give in, however, there are some pretty nifty rewards for being a child of the night. More aggressive combat skills, better life-draining options, the sweet fangs.

It may result in a bad ending or two, but it makes the game easier.
