Before I came here I used to produce many CS and CS:S maps. It is very fun, and easier then halo modding. You need Hammer Editor, preferrably the new one, because it has more features. I would go back to making the maps, but only you and anyone else can use them....unless you have a server and have it hosted. I play CS:S and am looking for people to play with on there. I have way too many hobbies, halo modding, flying, scuba diving, cs map making, video editing/fx. I am trying to cut back on them and find my most favorite so I can get my desktop organized!! Talk to me on AIM or MSN Messenger if you would like help with mapping. I still know a lot.

Good Luck
