Oh, u don't understand. He is the modificator, he made the game with the sources of HL1. It means, he used the sounds, textures, engines... anything he wants, from HL1.

If that sound is not from Valve, then Nexon cannot use it, because of copyright problem.

With AoM, that guy is the one who made the game, so he has the right to show his name in the credit.
