If you're an FPS fan, this might be the perfect controller for you. Hori's Tactical Assault Commander 4 is a keyboard and mouse setup for PS4 that attempts to mimic a PC control system. The means the DualShock 4's left analog is mapped to a WASD-style configuration, while the right analog is controlled by a mouse. The rest of the DualShock's buttons and triggers are mapped to the appropriate spots, and there are a couple of additional functions like programmable buttons, a "snipe mode" that changes mouse sensitivity and a walk button for, we assume, walking rather than running.
