Subroutine

A Subroutine is an item in TRON 2.0 and TRON: Evolution that provides a new weapon, protection, or a utility/performance enhancement by equipping it in the subroutine system menu (example below).

example of subroutine menu as it appeared TRON 2.0 for the Xbox/PC port

Every subroutine can be one of 3 levels, from weakest to strongest:

Alpha

Beta

Gold

Higher level subroutines usually have an increased energy cost or apply a higher cost to a weapon. In the memory ring, an alpha subroutine fills three blocks, a beta fills two blocks, and a gold fills one block. The configuration of blocks in the memory ring is tied to the computer system; an older computer will have less memory and therefore fewer blocks available.

To get better versions, a player must either find them while traveling through the game or use an Optimizer to upgrade the subroutines they have.
