It's been argued that horror and mobile don't mix. That it's much too hard to become fully immersed - and, by extension, scared - in an experience when the screen you're playing on is only a few inches big. Personally, I think that's a load of horsepucky. Games like Square Enix's Nanashi no Game have proven that a horror game doesn't have to be played on a massive screen to be frightening. And if its gameplay trailer is anything to go by, the upcoming In Fear I Trust for iOS will hammer that point home even more.
