A SECOND BEFORE US

They have no names, only serial numbers. They have no freedom, no memories from the past. You are one of them. Explore the last center of civilization on a shattered Earth to understand what is really going on.

Region: United States / North America. Check that the key's region matches your Steam account's country before buying — region-locked keys can't be activated elsewhere.

What you get: one unique, unused product key, shown on your order page (and in your account) once payment is confirmed — usually within minutes, and at most 24 hours. No physical item is shipped.

How to activate: open the Steam client, choose Games → Activate a Product on Steam, accept the subscriber agreement and paste your key. The game then appears in your library, ready to download.

Requirements: a Steam account and the Steam client. System requirements are set by the publisher and listed on the game's Steam store page.
