A dark turn-based strategy-survival RPG blending retro-futuristic urban fantasy with Slavic folklore. Customise your characters’ gender, class, and race, and recruit NPC allies to explore the wastelands, rebuild your colony, and engage in tactical card-based combat. Experience branching narratives and character progression, where every choice shapes your survival and the fate of humanity in this story-rich roguelite adventure.

Survive and Explore a Story-Rich Post-Apocalyptic World. Uncover the secrets of Thea through rich storytelling, engaging quests, and diverse points of interest. Scavenge vital resources and face environmental challenges as you navigate a retro-futuristic wasteland shaped by Slavic folklore and mystical ruins.

Project Thea for PC starts at €10.07 at Difmark, 50% under the €19.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €12.26 at Kinguin.
That €10.07 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Just 4 stores stock it, 4 offers in all, so there is little here to push the price either way.
The cheapest route is a shared account at €10.07 at Difmark: you get into an account that already owns the game, but it never becomes yours. A key for your own Steam account starts at €12.26 at Kinguin, €2.19 more, and that is the sensible option.
All 4 offers are Global, so the code redeems on any account no matter where it was created.
For most people the key at €12.26 at Kinguin is the sensible buy: the game stays on your own account and it is only €2.19 more than the shared account.
