Yes, Amnesia: The Dark Descent. It's legitimately free, not as a demo, not temporarily, but free as in permanently in your account.

Amnesia is a horror game based in exploration and stealth.

Just click install on the page (if you're signed in to Steam), and it'll add it to your account. No need to actually install it.
