Why it exists
Minecraft PvP is a real competitive discipline played on an engine that was never built for it. Three bugs define the ceiling, and all three are artifacts of the engine rather than the game:
- Reach desync — “how did he hit me from there?”
- Knockback inconsistency — the same hit, a different result.
- Whiff-based-on-latency — your aim was right; the network disagreed.
This project deletes them by construction. Not with a mod or a plugin — with a from-scratch engine where fair hit registration is the foundation instead of a patch.
128 Hz, fixed
The simulation runs at 128 Hz on a fixed timestep, independent of your frame rate. Minecraft runs 20. Click timing lands where you aimed it.
Server-authoritative
Clients send inputs, never positions. The server re-simulates every tick. That is the netcode and the anti-cheat foundation at the same time.
Real lag compensation
The server keeps a per-tick hitbox history and rewinds each target to what you actually saw when you clicked — the Counter-Strike approach, not a reach fudge factor.
Capsule hitboxes
Rotationally symmetric, so your hittable profile no longer depends on which way you happen to be facing. Reach stays 3.0 blocks.
1.9 combat, exactly
Attack cooldown, charge-scaled damage, crits, sweeps, and the sprint-reset W-tap — ported from the real values, not approximated by feel.
Free
No purchase, no ads, no battle pass, no cosmetics store. A hobby project and a tech demo, and that is all it is.

What it is, and what it isn't
It is a from-scratch game written in Rust. The engine, the simulation, the netcode, and the renderer are all original work. It is free, non-commercial, and unaffiliated with Mojang or Microsoft.
It is not a Minecraft mod, a client, or a server plugin, and it will never take your money. It uses Minecraft's textures and sounds to match the look and feel exactly, which is why it requires you to sign in with a Microsoft account that owns the game.
It is early. This is a pre-alpha. Expect rough edges, missing features, and builds that change under you.
Requirements
- Windows 10 or 11 (64-bit). macOS and Linux builds are not out yet.
- A GPU that supports Vulkan or DirectX 12.
- A Microsoft account that owns Minecraft: Java Edition.
- The installer is not code-signed yet, so Windows SmartScreen will warn you once. More info → Run anyway.
