Tron consists of four sub-games based on events and characters in the movie. In general, the player controls Tron, either in human form or piloting a vehicle, using an eight-way joystick for movement, a trigger button on the stick to fire (or slow down the player’s light cycle), and a rotary dial for aiming. The goal of the game is to score points and advance through the game’s twelve levels by completing each of the sub-games. Most of the 12 levels are named after programming languages.
The player must guide Tron to the flashing circle of an Input/Output tower within a set time limit while avoiding or destroying Grid Bugs. This game is based on the I/O Tower scene in the film, while adding the Grid Bugs as enemies (which were only briefly mentioned in the film).
The player must break through a rotating shield wall protecting the MCP cone and enter the cone without touching any of the shield blocks. This game is based on Tron’s final battle with the MCP in the film, but changes the nature of the MCP’s shield.
In a player-vs-AI variant of the Snake game concept, the player guides Tron’s blue Light Cycle in an arena against one or more yellow opponents. The objective is to force the enemy light cycles into walls and jet trails, while simultaneously avoiding them. This game is based on the Light Cycle Arena sequence in the film, though the colors of the friendly and enemy characters are reversed. This is the only sub-game in Tron to not use the rotary dial.
The player must guide Tron’s red battle tank through a maze and destroy all of the opposing blue enemy tanks by hitting each of them three times. The tank can warp to a random location in the maze by moving into a diamond in the center. In higher difficulty levels, the enemy tanks are replaced by red Recognizers that are much faster and attempt to collide with the player instead of shooting at him/her. This game is not based on any particular scene, but is rather based on Tank Program elements, including Clu’s failed intrusion into the ENCOM mainframe and the “Space Paranoids” game featured at the beginning of the film.
