Tier 4 - Warrior is the fourth tier of Quake 3 Arena. To survive here, a gladiator has to be at least as ruthless and indiscriminate as their opponents, if not even more. The environment becomes even deadlier and can offer threats or opportunities to the smart fighter. The maps' style is distinctly industrial, featuring numerous metallic textures, computer screens and machinery, including some Strogg-like designs. The Tier's Lord is the heavily "wired" Anarki who is very good at using his lair's layout to his advantage. A player who can outsmart and defeat such a cunning enemy will be hailed as a true Veteran.
