The Disc Wars are just one of many gladiatorial events played out in the Game Arena, where programs are placed into separate compartments and forced to fight using their Identity Discs. If the disc makes contact with its target, the opposing program immediately loses the game by way of deresolution. Gravity on the arena platforms could be reversed by small spherical devices that, if moved one way, would keep gravity normal and if moved the other way, would reverse it.
Combatants' names are visible on the floating circle-shaped leader board which appear to have been named after notable real-world computer scientists or other computer science subjects. The inconsistent presentation of these names (and reappearance of some of the derezzed competitors in the Light Cycle Grid) prevents them from being used to document them as minor characters.
