In Tron: Deadly Discs, the player takes the role of Tron, fighting successive waves of enemy Disc-throwers and Recognizers in a never-ending quest to achieve the highest score.

The game begins by giving the player a code. The player then progresses to a gridlike area with spiders and tanks, which hinder the player with melee and ranged attacks, respectively. Although the player can shoot these enemies, doing so quickly drains their energy. Therefore, avoiding contact and dodging shots is often the most efficient way of navigating the grid. When the player reaches the correct sector, they may enter their code to move on.
