Open ground. Fighters start at (40, 40) and (40, 42); zombies at (45, 40), (45, 42), (45, 44), as needed. Fighters use the existing Murderer melee archetype with Adventurer allegiance, its birth spear/shield, watch helmet/coat/gauntlets, and ten additional bandages. Natural attributes and cooldowns; no forced attacks, healing, target selection, or AI changes.
Moving and holding measure time alive until either team is defeated (or the recording ends). Holding means stationary in combat, including time between swings. Switches count changes to a different selected target, excluding initial acquisition. HP restored includes regeneration and all other sources; it does not imply bandage use. Bandage starts are reported separately. The arena has no town routines, terrain obstacles, respawns, or player. Facing is represented by the target line; native sprite facing/animation is not captured.
World runs at 60 ticks/second; measurements and damage events use every tick. The page displays 20 position samples/second. All displayed motion is recorded; the browser never simulates combat.
