Bottom line: For safe + easy + online play, buy CS:S on Steam (~$10). For legacy/offline only, search for "CS:S v34 master server fix archive.org" – those are generally safe.

Launch Counter-Strike: Source now. Click "Find Servers." The Internet tab should populate with thousands of players across de_dust2, surf_ski_2, and ze_potc.
