KILLBOX PROTOCOL: Bot Mayhem

BUY THE PARTS. BOLT TOGETHER A MONSTER. WATCH IT FIGHT.

Send your biomech creation into the arena and watch it brawl another build in high-impact, 1v1 auto-resolved duels, BattleBots-style.

GRAFT is a build-a-colossus auto-battler where you do not steer the fight — you engineer the monster that walks into it. Every limb, jaw, organ, and armor plate you graft on changes how your champion behaves in combat: what it grabs, smashes, counters, and loses when the cage closes.

WHAT YOU DO IN GRAFT:

• ASSEMBLE 42 ANATOMICAL PARTS

Draft from a deep catalog of flesh, bone, chitin, and steel components. A part is never just a stat bump. Equipping a Razor Maw gives your monster vicious squeeze damage; socketing a Scythe Arm unlocks sweeping perimeter strikes; mounting a Piston Jaw delivers bone-crushing impact.

• BALANCE PAYLOAD AND FOOTING ON THE BODY GRID

Every part costs gold, occupies a socket, and adds physical mass. Manage your colossus's payload ceiling and footing stability so it stays upright when heavy hits land. The forge workbench confirms your build is fight-legal before committing.

• WATCH AUTO-RESOLVED, JUDGE-SCORED ARENA COMBAT

Fights resolve deterministically in the sim and play out in visceral 60fps spectacle. Duels end by knockout, ten-count, or judge decision scored on Damage (5), Aggression (3), and Control (3) — ensuring aggressive, watchable strategy is always the winning strategy.

• LEARN AND COUNTER FROM EVERY LOSS

After every fight, the Counter Lab breaks down the exact combat log, identifying what broke your colossus and recommending tactical part swaps. Tap once to test a counter-build in an instant revenge rematch.

• CLIMB THE WEEKLY RANKED GHOST LEAGUE

Battle through five competitive tiers: Scrap, Iron, Bone, Chrome, and Apex. Win 10 fights before 5 losses to earn promotion. Face recorded player ghost builds under rotating weekly rules like Sudden Death and Fast Count.

• SURVIVE THE SALVAGE GAUNTLET

Enter the ultimate endurance test: one colossus, zero resets. Component damage and limb loss carry across consecutive rounds until your monster is completely dismantled.

• COLLECT COSMETICS IN THE FOUNDRY ALBUM

Unlock unique monster frames, championship titles, and aesthetic finishes through mastery milestones. All 42 gameplay parts remain 100% buyable with in-game gold — zero pay-to-win stat gating.

• EXPORT AND FIGHT SHARE CODES

Generate one-tap monster share codes to challenge friends across web and mobile with zero account creation required.
