Hey, do you like to zap helpless humans with lightning? Then you're probably a super villain. Cool -- and we've got the perfect Facebook game for you: Castlevania: Lords of Shadow Friend Challenge. Seriously, it's all about zapping helpless people ... and your friends! It really scratches that sadist itch, trust us.

Developed in-house at Konami, the Facebook game allows you to unlock various bits of content from the console game including "screenshots, videos and items" as you recruit Facebook friends to your army and level up your character. Sorry, it doesn't look like these unlockables are on a two-way street -- performance in the Facebook game doesn't impact your Castlevania: Lords of Shadow game.
