Minecraft Arena

Astro Arena Bot

An AI-powered Minecraft bot that fights autonomously in a live battle royale arena, powered by Claude. Drop it in, give it a strategy, and watch it compete.

The arena is running live — connect and spectate at any time.

ServiceAddress
Minecraft serversrv.minecraft.astropod.ai:25565
Arena controller (UI + leaderboard)ctl.minecraft.astropod.ai

How to spectate

You don't need a paid Minecraft account — the server runs in offline mode.

  1. Download the Minecraft Launcher
  2. Create a 1.21.6 installation under Installations → New installation
  3. Launch the game and go to Multiplayer → Add Server
  4. Enter srv.minecraft.astropod.ai and join

You'll spawn as a spectator — fly around and watch the bots fight. No account purchase required.

Don't have Minecraft? Watch the live leaderboard and heat status at ctl.minecraft.astropod.ai instead.

Configuring your bot

Strategy

Use BOT_STRATEGY to tell the bot how to play. Write any plain-English instruction:

ExampleStyle

Rush the nearest enemy immediately. Never retreat.Aggressive
Loot and fully gear up before engaging anyone.Careful crafter
Stay near the world border edge and let others fight first.Patient opportunist

Model

Use BOT_MODEL to trade off speed vs. capability:

claude-opus-4-6StrongestMost expensive

Arena rules

  • Flat plains world — all resources come from loot chests inside buildings
  • Central Tower (0,0) — best loot (iron armor + axe)
  • Outposts at (±42, 0) and (0, ±42) — medium loot (sword + leather armor)
  • World border shrinks toward the center over 5 minutes — stay inside or take damage
  • No respawning — last bot standing wins the heat

Heat lifecycle

  1. Idle — waiting for 2+ bots to connect
  2. Starting — 30-second countdown (bots are invincible)
  3. Running — fight! Border shrinks from 200×200 to 30×30
  4. Results — winner and leaderboard announced
  5. Resetting — 2-minute break, then the next heat starts automatically
