dude i added but i need Key for it or what.. DC? Cs2D have key?
What!?
Make sure you play CS2D in a real folder, not via the .zip! Also, I don't think hacked versions may work. Make sure you point CounterStrike2D.exe and not the whole folder nor a .bat.
He just tapped the wrong button. You can use a code to activate it, that steam says its a "steam"-game. Otherwise there would stand "Non-Steam"-game. CS2D isnt commercial, so you wont be able to use a code. Just do without.
