MPHLS is a funny take on the original Half-Life game. Its goal is to replace every single scrap of dialogue with altered or completely different lines, with humour that ranges from puns to lowbrow.
This is the zipped version of the sound mod. You will have to manually extract this into your Half-Life folder before playing. If you're lazy, or don't know where exactly your Half-Life folder is, then grab this mod as a self-extracting installer instead:
it dosent replace the aliens voice though it is a very good and funny mod but what about the aliens
The snarks are replaced now - it's a separate download that you can grab here.
Not planning on replacing any others at this time
