In The Hunting part1 - which is part movie, part game - you must fight or avoid zombies to rescue your girlfriend (who is near the farmhouse).

Filmed entirely in the first person, you wake up one morning to strange noises downstairs (which turn out to be the zombies). You are then presented with a series of choices throughout the game/movie and you must pick the right one by tapping or swiping the screen.

It doesn't take long to complete, but it's fun, easy to get in to, and kinda scary.
