Adventure

Adventure is a 1980 action-adventure game developed by Warren Robinett and published by Atari, Inc. for the Atari 2600. The player controls a square avatar whose quest is to explore an open-ended environment to find a magical chalice and return it to the Golden Castle. The game world is populated by roaming enemies: three dragons that can eat the avatar and a bat that randomly steals and moves items around the game world. Adventure introduced new elements to console games, including enemies that continue to move when offscreen.
