Ketsui: Kizuna Jigoku Tachi

Ketsui: Kizuna Jigoku Tachi DX is the first feature phone adaptation of the arcade game Ketsui: Kizuna Jigoku Tachi. Like the original game, Ketsui features a dark post-apocalyptic setting. In a world ravaged by climate change, the arms dealer EVAC Industries has been stoking tension between world powers to fuel weapons sales. A secret UN squadron is deployed in a last-ditch effort to eliminate EVAC and bring some form of peace to the world. Players have a choice between two different ships; the slow-moving Tiger Schwert has a wide shot, while the fast-moving Panzer Jäger has a focused shot. Both ships feature a lock-on mode; by holding down the shot button, the player shoots a tightly focused laser and the player's support ships lock onto the nearest enemy, allowing the player to strafe while continuing to shoot.

This adaptation features only three of the original game's five stages and simplified artwork, both of which were addressed in the Ketsui: Kizuna Jigoku Tachi DX rerelease the next year.
