About the game

Did you know?
INFRA was built on the Source engine and began as a project by a small Finnish team that formed Loiste Interactive.

These are not ordinary keys. A gift is usually region-locked and arrives through someone else's account — if the region does not match, the game will not activate. An account means you get someone else's login: the game never becomes yours, and it breaks Steam's rules. A DLC or a bundle is not the base game. That is why none of them count towards the price at the top of the page.

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.
