RAGNAROK — DOWNLOAD & PLAY

You need your own Steam copy of Terraria. Keep Steam running.

Windows: extract this ZIP, then double-click Set Up Ragnarok.cmd.
Mac: extract this ZIP, then open Set Up Ragnarok.command. If your Mac blocks it, use Finder's Open action or run: sh "Set Up Ragnarok.command" from Terminal in this folder.
Linux: extract this ZIP and run: sh setup-ragnarok.sh

Choose Low first. Setup downloads and verifies the pinned 1.45 GB modpack and the matching official tModLoader. It installs in your user folder, never needs administrator rights, and creates Play Ragnarok. Windows gets a desktop shortcut; Mac/Linux get a launcher in the install folder. Keep this setup folder for Check and Repair.

Windows install folder: %LOCALAPPDATA%\Ragnarok
Mac install folder: ~/Library/Application Support/Ragnarok
Linux install folder: ~/.local/share/Ragnarok

Optional: enable Calamity Texture Pack under Resource Packs. Rerun Setup to switch graphics presets. It backs up the profile's Mods and ModConfigs first. Players and Worlds are not deleted or copied over.

Check Ragnarok verifies local files and writes a small support report. Repair reruns verified setup. Normal config edits can appear as differences. Old backups are kept until you choose to remove them.

These are readable unsigned scripts. Windows/macOS may ask before running downloaded scripts. The Windows launcher uses a process-only PowerShell execution-policy setting; it does not change system policy. You can inspect the .ps1/.sh source before running it.
