Shin Megami Tensei: Devil Survivor Overclocked is the 3DS port of the 2009 DS strategy RPG based on the universe of Shin Megami Tensei. When Tokyo is ravaged by a mysterious disaster that unleashes mysterious demonic forces on the city, a group of youths gain the power to summon these demons. The characters must decide how to use this power as they struggle to survive and uncover the truth behind the cataclysm.
Players control a party of these characters they recruit based on decisions they made as they progress through the game's story. Turn-based combat takes place on isometric battlefields with tile-based movement, and many attacks are performed using spells and abilities granted onto characters from demons which they can also summon onto the battlefield. New demons can be recruited in battle and via in-game auction. As with previous Shin Megami Tensei games, new demons can also be created using Demon Fusion.
This game is also known as Devil Survivor: Overclock in Japan.
