Though we're still waiting to hear more on Kojima Productions' sword-swinging action title, Metal Gear Solid: Rising, the series' progenitor gave some hints about his next project in today's pre-E3 presentation. Kojima explained that he's working on a heretofore unannounced title that will run on the "Fox Engine," a new multiplatform development tool which Kojima Productions is creating in-house. A teaser image for the engine shows a PC mouse, a DualShock 3 and a 360 controller, seemingly indicating its compatibility with the three device's respective counterparts.

Kojima explained the engine, which Konami started developing shortly after completing Metal Gear Solid 4, is designed to ease the company's fairly laborious porting process between consoles, freeing Kojima's team to make even more games. We'll keep an eye out for more details on the Fox Engine at E3 next week!
