Why does a pizzeria - an increasingly unsuccessful one at that - need a night guard? Well, it seems the animatronic robots that entertain the children during the day - Freddy Fazbear, Bonnie the Bunny, Chica the Chicken, and Foxy the Pirate Fox - become active at night. Originally made for PC, the game sees you take on the role of night guard at Freddy Fazbear's Pizza. Now this is one of the creepiest games we've ever seen on a mobile platform. You can read our interview with the developers here. It is, however, a spectacularly executed piece of work, and a magnificent experience. It failed to get the attention it deserves, partially because it's not easy to categorise as either a novel or a game partially because it asks things of the user that go beyond a single screen and partially because it's so very realistic. It's sort of an interactive novel, but it's so much more: nearly 10 years in the making, it will send you crawling the web hunting for clues planted by the development team years before the app's release in July of this year. While it technically falls under the definition of an alternate reality game, Alfa-Arkiv isn't easy to categorise. The core of it takes place in the iPad app where you, as a new operator at a mysterious organisation, are reading through documents pertaining to the detention of a young woman named Rhea, a member of a resistance movement called the Liberation Army of Dagestan.

Alfa-Arkiv is about as ambitious a multimedia project as we've ever seen.
