It is a decent CS copy, but it has some flaws. There is no way to exit the game cleanly and also, after a few hours after installing it the sound is dead in the game. I checked the audio settings and everything is at max volume, but you cannot hear anything, not in the menu, not in the game itself. Please fix this issue with the sound. It is frustrating to play a game where you fire weapons without sound. FIX THE SOUND AND ADD EXIT OPTION. UNTIL THAT IS DONE YOU GET 1 STAR!
