Scary Granny Horror Game Unity Source Code

The horror survival game genre is one of the most downloaded and most played categories on the Play Store worldwide. Games like Granny have proven that players love the fear, the tension, and the thrill of sneaking around and escaping from a terrifying enemy. Now you can own your own version of this genre. 

Source Plunge presents the full Unity source code of Scary Granny Horror Game, a first-person 3D horror survival game where you are trapped inside a dark, abandoned hospital, hunted by a terrifying Granny, and must find hidden items, collect a door key, and escape before she catches you. With 5 progressive levels, a clear objective system, and a genuinely scary atmosphere, this is a complete and publishable horror game project.

What is Scary Granny Horror Game?

Scary Granny Horror Game is a first-person 3D horror survival game set inside a dark and abandoned hospital. You play as someone trapped inside this terrifying building, and your goal is simple: find the hidden documents, find the door key, and escape. But Granny is always watching, always lurking, and she can find you at any moment.

The game has 5 levels in total. The first level is unlocked from the start. Each of the remaining four levels unlocks after you complete the one before it. Before every level begins, the game shows you a clear Objective screen telling you exactly what you need to do in that level. You press Okay, and the horror begins.

The gameplay is built on stealth, exploration, and fear. You must move carefully through dark hospital corridors, use your flashlight to see in the darkness, crouch to avoid detection, run when Granny is close, and search every corner for the items you need to escape.
