After the release of Battle Garegga on Playstation 4 last year, M2 had additional games announced such as Dangun Feveron, Ketsui and Sorcer Striker. The necessity of releasing Ketsui on Playstation 4 is kind of high for me as the modern release of it on Xbox 360 and Playstation 3 doesn't seem to be quite enough as the Xbox series consoles were struggling in Japan and Xbox One took on a worse turn there. The Playstation 3 was slowly catching up like it's a good thing although the sales of the Playstation 3 release were quite low compared to the Xbox 360 release. There were interesting momentum and reasons to buy the Xbox 360 as of that time like tons of arcade-style games release on that system with the Playstation 3 taking turns next with tons of fighting games released for it as originated from the arcades.
Another problem is that games like Battle Garegga and Sorcer Striker were not quite easy to get for the Sega Saturn although the console succeeded in Japan at the time. Not to mention that Dangun Feveron NEVER got a console port until the Playstation 4 release and it seems that the Playstation 4 has been getting tons of arcade-style games and especially for those originated from the arcades.
As part of M2 Shooting Trigger project, the Playstation 4 release will have the similar M2 gadget interface design although the skin surely looks better than the one from Battle Garegga. Additional game modes will enhance the gameplay even further like Battle Garegga as well as the additional remix soundtracks, one for a club-style remix and the other is a retro-style which brings you back to the 1980s-90s arcade games. Another interesting thing is that the neon glow on the interface lights up to the music as if you're in the club. Not to mention that the M2-gadget interface isn't affected by the game's slowdown which is a smart programming from M2. It's nearly 20 years ever since the game not having a console release.
