Adventure (Atari 2600)

Adventure as the name suggests is an action-adventure game that was inspired from the 1977 text adventure game Colossal Cave Adventure. The Atari 2600 game is known for being one of the first action-adventure games for a console, but also the first to allow a stash of items, first to use a "fog-of-war" effect, and, of course, its famous Easter egg.

Hidden Developer Credit#

One of the first publicly-known Easter eggs hidden in a game, born out of frustration against Atari's policy of not crediting its developers. This can be accessed by either using the long way (below), or by setting RAM address $8A to 1E.

Long Way#

On difficulty 2 or 3, inside the black castle catacombs, embedded in the south wall of a sealed chamber (accessible only with the bridge) is an "invisible" 1-pixel object. You must bounce the cursor along the bottom wall to grab the dot. The dot is not actually invisible, but simply the same color as the wall and is easily seen when placed in a catacombs passage or over a normal wall. Unlike most other objects in the game, the dot is not attracted to the magnet.

Bringing this dot to the east end of the corridor below the golden castle while other differently-colored objects are present causes the wall object to also become invisible, allowing you to pass into a room displaying the words "Created by Warren Robinett".
