We're providing the DRM free version here, which Frogwares gave us for distribution. It's not the Steam version of the game. We pay Frogwares directly for every purchase made on Gamesplanet.

Here's the statement of Frogwares on the pirated version, in case you're interested in further details: https://frogwares.com/how-nacon-cracked-and-pirated-the-sinking-city/
