LAUNCHER
The modded client for Sequence. It builds a separate modded copy of The Isle beside your Steam install, keeps it up to date, and leaves your normal game alone.
[ INSTALLER ]
RECOMMENDEDMost players want this one. It installs for your user only, so Windows never asks for an administrator password, and it updates itself from then on.
SequenceLauncher-Setup.exe[ PORTABLE ]
ADVANCEDNo installer, and nothing written to Program Files — it runs from wherever you put it. It does not update itself, so you have to come back to this tab for every new version.
SequenceLauncher-Portable.exe[ LINUX / STEAM DECK ]
LINUXOne file, no installer, no admin. Save it, allow it to run (right-click > Properties > Permissions > allow executing file as program, or chmod +x), and open it. It updates itself. Run The Isle once through Steam first so Proton is set up — the launcher starts the modded copy through your own Proton.
SequenceLauncher.AppImage[ WHAT YOU NEED ]
- > Windows 10 or 11 (64-bit), or Linux / Steam Deck — run The Isle once through Steam first so Proton is set up.
- > The Isle, owned and installed through Steam. The launcher copies from it; it never replaces it.
- > About 11 GB of free space for the modded copy, plus room for the download itself.
- > A connection that can pull the island content once. It resumes if it drops.
WHAT HAPPENS NEXT
Three things surprise people. None of them is a fault, and all both have one click each.
WINDOWS TRIES TO BLOCK IT
CAUTIONOur build is not code-signed, so Microsoft Defender SmartScreen shows that blue box. It is the warning for a publisher Windows has not seen before — it is not a virus report, and it will happen every time until we buy a signing certificate.

- >Click Run anyway.
