About the game
The Origin Theory - Episode One offers a lighter, plot-focused take on survival horror, complete with a familiar villain, zombies, firearms, and other genre trappings. Rather than grinding through waves of enemies or slogging through bullet-heavy boss fights, the game leans into untangling its central mystery. This free-to-play adventure title was developed and published by Juhana Karhu in 2024.

Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. So before paying, check the seller's buyer protection.

What is an activation platform?
The service where the key activates — Steam, GOG, Epic or the publisher's platform. A key for one platform won't work on another, hence the separate filter.

Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
