Now with 100% more turrets syndrome!*
Replaces the speak and spell esque chatting of the Hazardous Environment Combat Unit marines in Half-Life Source (and GoldSRC Half Life, technically, but I recommend making a backup of the original file if you go that route though) with the voice of Axton the Commando from Borderlands 2.
* Warning : Turrets syndrome is not a real medical issue nor is it present in this voice mod pack
