Demosfen - the largest project on the Call of Chernobyl platform. It is based on the new x64 version of the OpenXRay engine, thanks to which the game has advanced improvements in terms of speed, which allows you to put a large number of graphic bells and whistles. You will find many new locations, several new quest chains, new models of characters and mutants, a full-fledged A-Life, new features, such as flying a helicopter and customizing weapons, and also, only here you will find open 3D sights. For the first time in the history of Call of Chernobyl - Bar "100 Roentgen" has been expanded, now it is the real capital of the Zone. To improve the character creation process and the parameters of the new game, the add-on "TRX: Fresh Start" was added. Constant work on the improvement of various aspects of the game, the introduction of new and unique content, the addition of new features and features - all this shows that the project Demosfen keeps up with the times.

Hello, does it work with Steam or only with a standalone version? (OK, just saw in one of the commments that it's a fully standalone mod).

How do I go about installing this? It comes in 3 parts with all the same filenames, so putting them all together in the same folder and running the installer wouldn't work.

Did you highlight all 3 files with 7Zip and then tell it too extract here? I did and it worked for me.

Just finished Anomaly, which had the same old levels, tried to grind my way through Dead Air and gave up, then tried this. Brilliant! New levels, expanded old and plenty of life in the zone. Looking forward to the next update.
