Editing Tron (video game) (section)

== Gameplay ==
''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: [[IBM RPG|RPG]], [[COBOL]], [[BASIC]], [[Fortran|FORTRAN]], [[SNOBOL]], [[PL/I|PL1]], [[Pascal (programming language)|PASCAL]], [[ALGOL]], [[Assembly language|ASSEMBLY]], [[operating system|OS]], [[Job Control Language|JCL]], and [[User (computing)|USER]].<ref name="3gcs">{{cite web | title = Tron Arcade | website =3gcs.com| url = http://www.3gcs.com/tron/games/tron/index.htm | format = Web | access-date = 2007-09-15 | quote = Information about technical specifications, cabinets, gameplay, level keywords. |archive-url = https://web.archive.org/web/20070702060611/http://www.3gcs.com/tron/games/tron/index.htm |archive-date = July 2, 2007}}</ref> The game supports two players alternating.<ref name="3gcs"/>

At the start of each level, the player is taken to a "Game Grid" selection screen divided into four quadrants. The player must choose a quadrant, each of which corresponds to a different sub-game. The sub-game in each quadrant is not known to the player until it is selected. If the player fails the game and loses a life, they are taken back to this selection screen and an icon representing that game is now visible. Failure to choose a quadrant before an on-screen timer runs out results in a sub-game being chosen at random. Once the player completes a particular sub-game, it is taken out of play until the start of the next level.

The sub-games are as follows:

;I/O Tower
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). A [[bit]] occasionally appears on the screen and can be picked up for bonus points.

;MCP Cone
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. Bonus points are awarded for destroying every block in the shield.

;Light Cycles
In a player-vs-AI variant of the [[Snake (video game genre)|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 cycles to crash into walls, jet trails, or each other, while simultaneously avoiding them. When an enemy cycle crashes, both it and its trail disappear. 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.

;Battle Tanks
The player must guide Tron's red battle tank through a maze and destroy all of the opposing blue enemy tanks by shooting each of them three times. The tank can warp to a random location in the maze by moving into a diamond in the center, and its shots bounce off walls or obstructions until reaching their maximum travel distance. 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.
