About This Demo

Welcome gladiator

A turn-based roguelike deck-builder where equipment defines your cards and positioning decides whether you are actually hitting the enemy or giving them a massage.

Create your own build! A weapon, offhand, armour, helmet, and boots—each with its own cards, mechanics, and combat identity. Then fight through five increasingly dangerous leagues: Bronze, Silver, Gold, Platinum, and Master.

Control the Distance and Phases

Combat proceeds with three different phases: preparation, movement and action. Study the revealed enemy intentions and passives. Move to your weapon's ideal range within nine-position lane. Remember! Positioning matters. Because obviously there is no way you can do stabby stabby with a dagger from meters away (or is there?).

Forge a Build

Choose routes through battles, elite encounters, events, shops, recovery sites, and league bosses. Collect new cards and run-long artifacts, then upgrade cards along one of two permanent paths: improve their efficiency with Edge or transform their behavior with Mastery.

Mix equipment to create distinct strategies—from close-range bleed and counters using gladius, crushing warhammer finishers, defensive shield play, or long-range Shard control. Optional trinkets can rewrite the laws of combat for everyone in the arena.

Leave a Scar

Defeat the Master to complete the run and unlock World Scar: a customizable difficulty system where you choose the modifiers that shape your next challenge. Earn Marks to unlock new equipment in the Armoury, discover artifacts, experiment with seeded runs, and refine yourself.

Every death will give you another way to conquer the Arena.

More will come from early access

The arena secretly withholds lore and story, which will be revealed along with more enemies, equipment, events and more. Balance will continuously be looked into by reading what community wants. But I have no intention of stopping powerful builds users have found out on their own. I believe that is part of the fun!
