You need to have counter strike source installed to play trouble in terrorist town.
Nope, buy the game and play for free.
Download Counter Strike Source. Play Counter Strike Source. Delete Counter Strike 1.6 It's 2012 for christ sakes.
I use windows 7 and I play source fine.
There is no Counter Strike 2.0, but i think Valves new game Counter Strike Source would count. New graphics, maps and stuff like that. It's run on the source engine. What you do is download a program called steam, find the steam store, find counter strike: source there, buy it and it will download. Then you can play :D
