Half-Life 2

You must all be retarded.... CS1.6 is NOT going to be in the Source engine considering it is already in beta phase they aren't going to make a major change like that... and if you haven't seen the HL2 E3 demonstration, then get your ass over to fileplanet and wait an hour and a half for it ( download time is 35min average with cable, the video is 23 minutes long ) it's most definately worth it...
