About the game
A co-op horror adventure for up to four players following an expedition hunting treasure in a cursed jungle. Monstrous creatures warp reality around you, so staying clear-headed matters as much as fighting and exploring.
Did you know?
The game draws on H. P. Lovecraft's novella 'The Mound', which he ghostwrote for Zealia Bishop and which introduced the underground civilization of K'n-yan.

Listed seller price shown — payment fees may vary by method.
Offers that are not a key (Gift) — show (1) Gift: the game arrives as a Steam gift and works only in the region it was bought for.
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.

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.
Which key region should I pick?
Global activates everywhere. Regional keys (Europe, North America, RU-CIS) only work on accounts from that region — use the Region filter to match your account.
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.
