Elf Adventure © 1983 Atari, Inc.
This version of Elf Adventure is in a very early state and appears to be graphically quite similar to the original Adventure.
Warren Robinett was working on a sequel to his smash hit Adventure in his spare time while working at The Learning Company which he founded in 1980 after leaving Atari. It is unknown if Atari actually ordered a sequel or if Robinett was doing this on his own and hoping to sell it to Atari.
