Tron: Deadly Discs

Tron: Deadly Discs is a game released for the Intellivision. It is loosely based on Disney's motion picture, TRON. It was adapted for use on the Atari 2600.

Gameplay
The player controls TRON, who in this game is a red man with a yellow Disc. He is pitted in a square arena with black walls. Enemies will appear through doorways and throw their Discs at him. The player has to eliminate all the enemies with his own Disc, as well as surviving bonus rounds against the RECOGNIZER.

The player can throw his Disc in eight directions. When thrown, the Disc first appears as a thin horizontal line and can only move in a straight line. While in this mode, his (and any other Disc thrown in the game) can inflict damage, and can also "lock" doors (see below). When it reaches the wall (or when the player calls the Disc back by hitting any directional throw button), it automatically floats back to the player and appears as a square. It is harmless in this mode.

Unlike enemy Disc-throwers, TRON can block enemy Discs with his own. When an enemy Disc is blocked, it is destroyed and the enemy is temporarily disarmed until a replacement Disc floats in ten seconds later.

The doorways enemies appear in can be "locked." Initially they are blue, which means they are unlocked. If TRON hits the door with his Disc, or runs through it, it turns green and is locked in place. The doors reset when new enemy Disc-throwers enter the field. Any doors that are locked remain open. This is important because if the player locks two doors that are parallel to each other, he can run through one to warp to the other side, which heals the player and makes dodging and disc retrieval easier. Enemy Disc-throwers can't use the doors.

If all enemies are removed from the field after TRON has warped through two parallel doors, a RECOGNIZER will appear. The RECOGNIZER can be seen as a kind of bonus round, for there is a huge reward for damaging it.
