No installs, no complicated setup, no runtimes to fetch. Follow along.
Head to Pricing, pick a plan that fits your play time, enter your email at checkout.
Within seconds of checkout you'll get an email with your license key and a download link for the loader. Check spam if it doesn't show up in a minute.
Double-click the file you downloaded. A small window will pop open with a login screen. That's it — no install wizard, no configuration.
Paste the license key from your email. On first login the loader binds the key to this PC. Tick Remember me so you don't have to type it again next time.
Hit the big button. The loader launches the game for you and everything else happens in the background. Overlay opens automatically — menu key is Insert.
