Choplifter!, a well-known arcade and home console game, arrived on the Atari 7800. The original title, known for its action-packed gameplay of rescuing hostages and dodging enemies, was likely ported to this system to capitalize on the game's popularity.  Atari Corporation, or a licensed developer working for them, probably handled the conversion.  The European and US releases would have likely involved the core gameplay of helicopter-based rescues and combat, though there might be differences in some aspects of the game like the visual presentation.
