: If you have a physical disc, the key is typically found on the back of the inlay or inside the box.

However, the game uses an older system. Unlike modern Steam keys that auto-activate, STDS requires a manual 16-character alphanumeric code. Because SCS Software no longer actively sells this title on most major platforms (it has been delisted from Steam in several regions), finding a clean, updated activation key is tricky.

: Purchase directly for a digital key redeemable on Steam or for the standalone version.

If you want, I can draft the exact in-game copy for several languages, a support email template, or the API contract.

Disclaimer: This post does not provide cracks, keygens, or stolen activation keys. Piracy harms small developers like SCS Software.
