Developer: David Lubar

David Lubar programmed Sentinel, a 1990 light-gun game developed by Imagineering and published by Atari, very late in the console’s life. It was the only released 2600 game for the Atari XG-1 light gun. You protect a glowing orb drifting across four alien planets by shooting whatever attacks it, an idea that follows the arcade game Crossbow.
