The game has been updated to run on Windows 8 and 10. In addition, Russian and Czech languages were added to the international version of the game.

UPD: Since many players reported that the update caused problems for installs with TF mod, it was taken down for now. We'll try to find a solution so they work together.

UPD2: The update is available as an option. To access it, open Steam properties of the game and select 'beta' on Betas tab. Please note that if you have the game and TF mod already installed, modded files will be overwritten after selecting this beta version.

Install this beta update if you want to play vanilla version of the game on Windows 8 and later and/or want Russian or Czech language (the default, old version of the game may not run on Windows 8 and later without TF mod or custom fan made executable). If you want to play with TF mod, use the default version of the game since the mod enables the game to run on Windows 8 and later as well.
