You will get:
Counter-Strike: Global Offensive (aka CS:GO)
Counter-Strike: Source
Counter-Strike: Condition Zero
Counter-Strike.
Don't forget to use the code.
P.S.: I know it has been cheaper before but right now this is the cheapest I could find and it is over 50% off, so I think it is a good deal.
Enjoy.
Not a bad deal… Go go go!
