One of the most successful horror adventure games for Android in recent times is Granny. It is based on a very straightforward approach: you have to escape from a house trying not to be seen by your captor. The game's success stems from the atmosphere the developers were able to recreate. Players find themselves locked in an old house where the jailer is a less than lovable lady... rather a terrifying old bat who will kill you if she finds out that you leave our room.
Play Granny in silent mode
Granny MOD is a modified version of this adventure game where players can go around the house without making noise and hiding where you can. You will have to find hiding places, keys, and other objects to clear your way (closed doors, mainly) and try to be as discreet as possible at all times. This is where this MOD comes in because it lets users move about undetected unless you enter the monster's field of vision.
