Gauntlet: The Third Encounter is an arcade-style action game by Atari, that was released on the short-lived Atari Lynx handheld in 1990. The game can be played by one to four players simultaneously. It introduced new character classes like “Nerd” or “Punkrocker” and was one of a few games that used the “vertical mode” of the Atari Lynx, another being the port of Klax. The story: a crystal falls from the sky and lands in a castle, and it must be retrieved from within its 40 mazes type area.
Robert A. Jung wrote in his review on IGN that "Gauntlet: The Third Encounter is not a Lynx adaptation of any of the Gauntlet arcade games. Instead, this was originally a similar game developed by Epyx called Time Quests and Treasure Chests. When Atari bought the rights to the Lynx, they gave it a quick name change in hopes that the Gauntlet title would enhance its market appeal."
