At the last link (Tier 7 or Tier Z), the player fights with the champion of the Arena - Ziro. After the victory, the player moves along the links where he fights with other 'gladiators'.
He is greeted by the unknown voice of one of the Wadrigars: 'Welcome to Quake 3 Arena.' After that, the player enters the first arena in which the first battle takes place. He appears in a room furnished with computers. The player begins his 'path' from the zero link (Tier 0). But only the strongest of the gladiators can go further until he meets Ziro, the champion of the Eternal Arena. When dust and blood settle, the warriors continue their struggle, entertaining Wadrigar. Even death can not defeat the Wadrigar warrior - a fallen warrior is immediately reborn and returns to battle, perhaps even more experienced. In order to win, the gladiator needs not only to survive, but also to defeat his rivals.
They send the best gladiators of all time to the Arena. Nothing is known about these creatures, except that they like to watch the massacre in the heat of battle. Centuries ago, the mysterious race Vadrigar built the Eternal Arena - a place for gladiatorial battles, which were the entertainment of Vadrigar.
