Not only is the source code out there but an alpha/beta/whatever complete w/ levels and some e3 maps too. I think the hackers trying to make a point about how characters AI is NOT as good as the guys at E3 (ON TAPE) said it was. He should have just made an video of the scripted sequences and throw away the source and game, not publicly rape Valve. Seems kind of unnecessary. The engine IS great and theres nice physics w/ objects and ragdoll physiscs. Decals look sweet including on characters when you shoot them. Reminds me of Oflashpoint when you shoot someone in the face. Who has this for sure will buy the game, maybe even more since most likely they will show it off with friends. I dont think this will hurt Valve, it should stop the idiots that are full of **** at e3 from lying about features hopefully...
