Mad Professor

Players are about to meet a mad professor. They say he needs new guinea pigs... You are a group of friends who love exploring abandoned buildings. One day you decided to venture into a recently abandoned morgue. It seemed like just another adventure, you've been in similar places a thousand times. But things didn't go as smoothly as you thought. Scampering around the morgue, you bumped into a stranger. He behaved very oddly, constantly looking for something. Frightened, you ran towards the exit, but it was already too late. All the doors were locked. The stranger followed right behind you. After talking with him, you learned that this man was a former morgue employee, a mad professor. He explained that all the doors lock upon entering the building. Now, to escape, you need to help the professor open all the mechanisms of the abandoned morgue.
