File:Quake3.png Tier 7 - Elite, also known as Tier Z, is the seventh and final tier of the Quake 3 Arena single player campaign. It consists of only one map, which is the home of Xaero - the supreme Arena Lord and the deadliest opponent in the game. Defeating him in fair combat makes the player the new Arena Lord and allows Xaero to ascend to a higher level of existence (possibly becoming one of the Arena Masters).
