About

Grab a longsword, axe or mace, strap on armor and walk out onto the sand of a roaring Minecraft Colosseum. Then survive.

Steer every swing with the mouse. Hold left mouse and move it to drive the blade, the way Half Sword does. How fast the tip moves sets the damage. A lazy touch bounces off, while a full swing takes limbs off.

Armory: Longsword, Bearded Axe or Flanged Mace, plus Gambeson, Mail Hauberk or Plate Harness. Heavier armor protects more and slows you down.
Real weapon physics: damage is the weapon's momentum at the point of contact (impact energy for the mace). It depends on its mass, where on the blade you hit and whether the edge lands square. The longsword can thrust through armor gaps.
Active-ragdoll knights: every fighter is a physics body held up by muscles. Blows shove them, and they stagger, get knocked off their feet and climb back up. A mace to the head drops them.
Blade on blade: your sword binds and parries against theirs, a hard parry can knock a weapon out of their hands, and holding your blade in the path of their swing blocks it. Better knights raise a guard when they see a big swing coming.
Hit locations: head, torso, arms and legs take damage separately. Armor can deflect a blow with sparks and a clang. Maces punch through plate, and blades cut cloth.
Max chaos gore: heads and limbs come off and tumble across the arena, stumps keep bleeding, the dead drop as ragdolls and the sand turns red.
Endless waves: peasant brawlers, squires, men-at-arms, knights and arena champions get tougher every wave. Your best wave is saved.
Solo, single player.
