InSide follows the story of a middle aged man, who wakes up in a hospital after a car accident. In this survival horror, the player has to escape this hospital without losing his mind, and without any weapon.
The level design is very important in this game as the player will have to think of a way to go past the enemies without being noticed or harmed. While the time goes by, the fear of the main character will get stronger and he will start to see some illusions coming from the floor. These illusions can be killed by the player but put him at risk and under pressure, so he has to think and act fast in order to avoid these creatures.
