Ketsui: Kizuna Jigoku Tachi Extra is an updated version of Cave's arcade bullet hell shoot 'em up Ketsui: Kizuna Jigoku Tachi. The porting was handled by 5pb. Pre-orders for the game included a guidebook. The Limited Edition features a 2-disc soundtrack with music from Ketsui and DoDonPachi Dai Ou Jou.
On March 18, 2013, 5pb announced that a Playstation 3 version was in development and would be released on July 25 of the same year.
A handful of features were added to the console release to complement the standard arcade mode. Aside from the standard leaderboards, uploadable replays, and training mode features, a few unique features not found in all Cave console ports were included.
One of the primary unique additions to the console release is the addition of X-Mode, an arranged gameplay mode that changes a variety of mechanics from the original version, such as the way score chips are generated, and a different suicide bullet mechanic. It's also somewhat easier than the original arcade mode.
In addition to other "extra" options settings like forced loops and unlimited lives, it's possible to play in "no-bullet" mode, which prevents all enemies and bosses from firing any bullets. This is mostly just useful for learning stage layouts and practicing chaining routes.
