Are you searching for easy and simple patching system for your game? I'm glad to see you here! Here we've got what you're exactly searching. 

DarkPatcher offers you an easy way to create launcher for your game. You are not locked in boring system interface windows. You can create your launcher as Unity application! This means that you can even add flying space-ships in the background to improve effect of your launcher. What about patch creation ? There's nothing easier than this! You have to only select versions of your game - everything else is done by our library. 

New version is right here! Support for Linux & Mac and more stable patching system. For previous version users (1.x and 2.x) - please abandon previous project and create the new one with this version. Old version is no longer supported and developed.
