Which Atari 2600 Game Was the Adventure Sequel?

The search for a follow-up to the classic Atari 2600 title Adventure leads to a complex history involving unreleased prototypes and homebrew developments. Although no official sequel reached store shelves during the system’s commercial lifespan, the project known as Adventure II is recognized as the direct successor. This article details the legacy of the original game, the cancellation of the sequel, and its eventual release decades later.

The original Adventure, released in 1980, was a groundbreaking title created by Warren Robinett. It is widely credited as the first action-adventure game and the first video game to feature an Easter egg. Players controlled a square knight exploring a kingdom to recover a chalice and return it to the gold castle. The game’s open-world design and hidden secrets cemented its status as one of the most important games in history, naturally leading to expectations for a follow-up.

Warren Robinett began work on a sequel, internally titled Adventure II, before leaving Atari in 1981. His departure halted the official development of the project, and Atari never completed or released the game during the lifespan of the 2600 console. For over twenty years, the sequel existed only as a legend among collectors and historians, with prototypes and design notes circulating within the retro gaming community.

The game finally saw a form of release in 2002 when programmer John Payson completed the code based on Robinett’s original design documents. This homebrew version allowed fans to finally play the intended sequel on real hardware via flash cartridges or emulation. While it was not an official commercial product from the 1980s, Adventure II remains the definitive answer to the question of what game was designed to follow the original Adventure on the Atari 2600.
