PLease, somebody has CounterStrike:Source?

And can i play it with steam?

i am new at these type of computer game's.

uhhhhhhhhhhhhhhhhhhhhhh CSS is pretty much a steam game... period lol

I had it and deleted it after a very weird common problem. Somehow (although it doesn't have that high graphics) it makes my CPU usage reach 99% o.O . I looked up the problem and found out that many people have same problem with null solution so I deleted it
