This week's prize is certainly... unique. Train to be a despicable bioterrorist by spreading your very own deadly pathogen worldwide, all in an effort to eradicate mankind.
In Plague Inc: Evolved, you'll begin by infecting a 'Patient Zero' and from there continue to evolve your virus in an effort to overcome humanity's best defences. If you can adapt and survive, spreading the plague on a global scale in this rather unnerving strategy-simulation game, then congratulations - you've wiped out your own species!
In the worrying event that appeals (who am I kidding, it does sound like fun), enter via Gleam below for your chance to win a Steam key. If you aren't drawn as the winner and you really must spread misery, then Plague Inc: Evolved can be purchased for £11.99 on Steam, Xbox One and PS4.
