i play CS:S. I was actually rather good at it for a stage there but as steam tends to do everynow and then it stuffed up on me and i havnt bothered redownloading it sence. ATM id have to say dont bother playing it if you have COD4. Its just that level above now, however it does make a good change of pase. If you get on a good server i dont have problems with Hax. For the NZers/Aussies play on internode/pubgamer - Always good.
