Universal Chaos is an action game published by Telegames for the Atari 2600 in 1983. It supports up to two simultaneous players sharing the same keyboard — a natural fit for the score-chasing, sit-beside-a-friend play style of the era.
How to play
Controls use a joystick-to-keyboard layout for both players.
- Player 1 — move: Arrow keys
- Player 1 — fire: Spacebar
- Player 1 — turbo: Del
- Player 2 — move: T / G / F / H
- Player 2 — fire: A
- Player 2 — turbo: . (period)
Shared controls: F12 = Reset, F11 = Select, Alt+P = Pause, F2 = colour/B&W toggle, Alt+L = paddle/joystick mode.
