Download for Windows

One small program, MachbreakLauncher.exe. It installs the game and keeps it current for as long as MACHBREAK exists.

Download MachbreakLauncher.zip

A few MB, Windows 10/11. The same launcher serves both channels.

Unzip it and run it once. It copies itself to your own folder (%LOCALAPPDATA%\Machbreak), puts a MACHBREAK shortcut on your desktop, fetches the game and lights up PLAY. Use the shortcut from then on.

Windows may say "Windows protected your PC": More info, then Run anyway. The build is unsigned, that is all.

What it does

  • Installs once, to your folder. No admin rights, no installer wizard, nothing in Program Files.
  • Keeps the game updated. Every start checks for the build the server runs and fetches it before the game opens. It keeps itself current the same way: you never download anything from this page again.
  • Needs no account. Pick a name in the launcher; that is what the others see. Nothing to register, nothing to remember.
  • Starts offline too. The installed build runs when the host is unreachable; it just cannot update.
  • Two channels, one launcher. Live and PTR install side by side; switch in the launcher, and nothing is re-downloaded when you switch back.

PTR

PTR is the test build; Live is what everyone plays. The PTR runs the build the owner is testing, a step ahead of Live, on its own server (MACHBREAK-PTR, 5.78.41.181:28810); it can break, and it moves without notice. That is the point: play it, and tell Chris what broke.

Build b261029-d1ba588b, published 2026-10-30 08:04 UTC.

Live

Live is what everyone plays: the stable build, a step behind the PTR, on its own server. The Live page.

Build: see the Live page.

The launcher shows this same feed for the channel it is on.

What you need

Windows
Windows 10 or 11, 64-bit.
Graphics
A GPU with Vulkan: any card from the last eight years. Without one the game falls back to the Compatibility renderer (OpenGL 3.3): plainer, still plays.
Disk
About 300 MB for the launcher and the game. A second channel adds its own copy.
Network
An internet connection to install and update; the installed build also starts offline. If the Windows firewall asks, Allow access.
Input
A mouse. It is a fast shooter.

Something broke?

  1. In the launcher, press SEND LOGS (the small text in its footer). It packs the last game logs into %LOCALAPPDATA%\Machbreak\logs\send-to-chris.zip and opens that folder. After a crash the launcher packs it on its own and says so at the next start.
  2. Send that zip to Chris, the way he sent you this link, with a line on what you were doing when it went wrong.
  3. Nothing is uploaded by itself: the zip is yours until you attach it.

For the careful

Hashes of what this page serves, and the game zip on its own for anyone who would rather not run the launcher (unzip anywhere; the launcher is still the way to stay current).
