On launch, Alyx only said "here we go, we did it Gordon." Once. This broke in the 2010 update to have her say the line twice. This fixes that so now it's reverted back to how it was.
I didn't make this. Just uploaded here for attention. This is actually part of a bigger mod which you can find here https://gamebanana.info/
Warning: The pack from the link is out of date so be wary of downloading any part of it outside this upload.
