Arcade Classics: Defender + Joust is a compilation of two classic arcade games that was released for the Game Boy in 1995. The two games include Defender and Joust. Nintendo published this game and Williams Entertainment developed it. The game accompanied three other games within the Arcade Classics series, though they weren't developed by Williams Entertainment (note: they were all published by Nintendo however). If you play the game on the Super Game Boy, it features enhanced graphics.
