First release date

Katana Engine, formerly known as KTGL (Koei Tecmo Game Library), [1] is a game engine developed by Future Tech Base, formerly known as the Technical Support Department, [2] which is the R&D department within Koei Tecmo responsible for developing game engines among other things. [3]

Development of the KTGL engine started around 2000, in order to develop games for multiple platforms with great efficiency. At the time, the KTGL engine was just a software library with individual production tools. Only in around 2010 did the development of a full-fledged integrated production environment start. [4]

AI technology is increasingly used in order to streamline the development process. Most Koei Tecmo titles have been developed using the Katana Engine as of 2024. [5]

    "元々2000年代前半にソフトウェアライブラリと個々の制作ツールとして作っていたものがあって,それを,統合的な制作環境がないと難しいなという話になって……2010年頃から本格的な統合制作環境としても開発し、今にいたります。"
