For those console owners who prefer a keyboard and mouse to a controller, there's this.
Called the Tactical Assault Commander for PlayStation 4, the keyboard and mouse can be also be used with the PS3. The keyboard has arrow keys as well as a "Snipe" key, a "Quick key," and a "Walk key." It also has a PlayStation button and a Dpad.
According to My Game News Flash, the Tactical Assault Commander for PlayStation 4 will be out on November 30 in Japan for 14,904 yen ($164).
Neat, but not sure how comfy it would be playing on the sofa.
