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.

FAQ
Are keys from these stores legal?
Buying is legal — keys come from the grey market, so a small deactivation risk exists. That's why we only list sellers with 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.
What's the difference between editions?
Standard is the base game; Deluxe usually adds an expansion or bonus content. The edition filter shows exactly that variant, with no mixed prices.
