Questions

Is it really free?

Yes. SSTR Demo is free right now on Steam, with nothing to pay.

Is this the full game?

No. A demo is a portion of SSTR Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.

Where do I claim it?

On the official Steam page. We link straight there — we never host game files or act as a middleman.
