Who you gonna call? Well, no-one if you are playing the latest Capcom release on your mobile. Yes, the publisher has sneakily released a new Ghostbusters game on iOS and even better, it's free-to-play.
Ghostbusters basically takes you with recruiting new members before going on to tackle supernatural foes across New York. Combat occurs in real-time and the game also allows you to unlock new equipment, squad members and abilities.
There are in-app purchases obviously, but don't let that put you off.
