Cool arena combat game where you face off against 3 enemy combatants as the Disney hero TRON. You each have a disc that can either be used as a weapon or a shield (to protect from other disc being thrown at you). Different enemies have different combat skills or intelligence, or may have stronger discs that can do more damage to you (you can initially take 3 hits, but later in the game at 20,000 points you can take 4 hits and at 100,000 you can take 5 hits. You can fling your disc in all 8 directions (angular shots can take enemies by surprise) and you must wait for your disc to return before you can fling it again. As you wait, pressing the number keys will make it return faster-- but stop pressing before it's in your hands or you'll throw it needlessly! Doors that the enemies emerge from can be "jammed" if you throw a disc directly in the middle of them. When the giant robot "recognizer" comes to fix the doors, you will have a chance to kill him with a perfectly thrown disc to his white eye. He will not only start fixing the doors with a giant black square, but he will fire a homing paralyzing ray that will freeze you until he's ready to leave. Killing him nets a nice bonus, as does lasting a long time in this game-- enemies get very lucrative the further you get (up to 10,000 points apiece!). If you take a lot of damage (you slow down when damage is incurred) you can warp through doors across the arena from each other and restore a hit. This may not seem terribly fun at first glance but it will grow on you eventually.
