The alpha builds aren't signed yet, so each system will want a word with you once. After that they start like anything else.
Unzip, then right-click the app and choose Open. A plain double-click gets refused by Gatekeeper.
On recent versions that isn't enough either. Open System Settings → Privacy & Security, scroll down to Security, and click Open Anyway next to the note about Terra 500. Once only — after that it opens normally.
Unzip, run terra-game.exe. SmartScreen shows a warning: More info → Run anyway.
Unpack the tar.gz and run ./terra.sh. Needs a 64-bit distro with a working GPU driver.
You only download from this page once. The game checks for a newer version when it starts and offers to update itself: it fetches just the parts that actually changed — usually a few megabytes rather than the whole download — verifies them, and restarts.
You can put it off and keep playing, but multiplayer stays closed until you update. The rules of the world can change between builds, and an out-of-date client would quietly disagree with the server. Single player keeps working either way, even with no connection at all.
