Difference between...

[Badgez]

What are the differences between CS: Condition Zero and CS: Source?
I don't know which one to get. My brother has Condition Zero and its pretty good... I like it, but I've never played Source. Are the controls different, or is everything different? Thanks.

I dont really know the difference but I have Counter Striek Source and its excellent, Well worth trying.
