Within is an action-based puzzle video game developed by Apogee and published by Sony Computer Entertainment. It is the first title by Apogee as well as one of the first major releases for the PlayStation 4, being an exclusive for the console. The game was released worldwide on November 26, 2013.

Gameplay
Within plays in a third-person format with major stealth, puzzle, and platforming elements. The main purpose of the game is to overcome obstacles and other puzzles that will require extensive logical prowess in order to proceed.

Plot
The game's main storyline is predicated on a device known as the Mentis, which allows people to enter the realms of their own minds. This capability eventually leads to the Mentis being marketed as a tool for psychotherapy. Because the Mentis can be used almost universally, experiences with it are widely varied. This is due to how the Mentis projects the physical aspect of an individual's mind. How one experiences the projections is based on their disposition, personality and state of mind.
