Darkness is inherently scary. The fear of the 'invisible' threat can turn even the bravest soul into a quivering wreck.
That, at least, is what Naquatic, the developer behind new undead shooter Affliction: Zombie Rising, hopes, for its latest game pops you in a very dark room with just a gun and torchlight for company.
Oh, and zombies. You probably guessed that part, mind.
Keeping ahead of the crowd
For some reason, the company is pegging this as a "virtual reality zombie shooter", though it looks to us like a straight firefight between you and the living dead - complete with a selection of increasingly powerful ordnance to aim at their heads.
A two-player co-op mode is included (with online matchmaking), so you can blast up the undead with a friend, should you not be brave enough to take them out on your own.
Affliction: Zombie Rising will be staggering onto the UK and US App Stores from tonight as a Universal app, priced at 69p / 99c.
