We know Hori's gaming equipment for the PS3 as the Tactical Assualt Commander 3, which consists of a keyboard and mouse. On Amazon Japan, a new version is now being listed as Tactical Assault Commander 4, which will be compatible with the PlayStation 4.
The keyboard and mouse emulating the DualShock 3/4 and is a nice companion for first person shooters. Tactical features like a snipe mode can fill the gap of responsiveness of the mouse while aiming.
Users on the internet found the Tactical Assault Commander 4 on Amazon UK as well, for a pre-order price of £86.35 delivered on October 9, which suggests that it will be widely available in the West soon.
