Famitsu has the first details on the Square Enix X ByKing action game. The game is called Gunslinger Stratos and it uses a unique double gun device which gives players two pistols. The game supports four on four battles and is described as an action shooting game.
Gunslinger Stratos appears to have an impressive credit reel with Nouki Kadoi (Lord of Vermilion) as the producer Shinichiro Obata (a planner on Marvel vs. Capcom) as the director, and Gen Urobuchi (Nitro+ and Madoka Magica writer) as the core staff.
Bayonetta character designer Mari Shimazaki, mecha artist Shigeto Koyama, and Arco Wada are also tied to Gunslinger Stratos as character designers.
