Warlock is a Halo 2 multiplayer map that is a remake of the Halo: Combat Evolved multiplayer map Wizard.

Warlock is similar to a dungeon, dark and gloomy. A small level, it has four bases close to one another, teleporters on all four sides, transporting the player to the opposite side of the arena. In the central cavity is an Active Camo inside a mid-column bulge. The outer edges are used in each base as a housing for turrets at each base's ledge, accessible by a fan propelling upward. Warlock was added to Halo 2 in the Bonus map pack.

Warlock features the same weapon lineup as Wizard, except for some minor changes: the Assault rifle has been replaced by the Battle rifle, the addition of the SMG and the removal of the Overshield.
