MundOT — Tibia PvP without levelling a character

Windows

Open MundOT-Setup.exe. It installs MundOT in a few seconds and starts the game. It does not ask for administrator rights.
The first start downloads the game files. Leave the client open until the download ends.
Windows shows a SmartScreen warning, because the installer is not signed yet. Choose More info, then Run anyway.
After that, start MundOT from the Start menu or the desktop shortcut. To remove it, use Settings, then Apps.
If you used the old ZIP version, you can delete its folder. The installer does not need it.

Extract the archive with tar -xzf. This one does create a folder, named after the build.
Run the mundot binary inside that folder.
If it does not start, give it the executable bit with chmod +x mundot.

There is no macOS build yet. It isn't ruled out — we may add it later — so play from Windows or Linux for now.

You download the client once. It updates itself from then on.
Sign in with your email address and password, not with a character name.
Create your account and reset your password on this website. The client offers neither on purpose.
