After defeating a requisite number of enemies from one time period, a mother ship appears. This allows shots to reach many different angles as you fire and turn. Your plane remains centered on the screen as you steer, and although you can only point it in 8 directions, turning the plane allows it to sweep through each direction to align with your joystick. A single 8-way joystick controls your plane while a pushbutton fires 3 consecutive shots forward. Time Pilot is a vertically-oriented single-player (or two-player taking turns) shooter in which you fly a modern jet fighter through time against enemies from each era of aviation.

The game draws the first string on even-numbered frames and the second string on odd-numbered frames. There are two copies of the Konami copyright string in the game: One at 0x086D (Konami) / 0x086F (Centuri) / 0x086C (Atari), and another at 0x4902 (Konami) / 0x4925 (Centuri) / 0x487F (Atari). 1.6 Phase Five - Special Copyright Checks.
