A single player campaign. You must fight your way to the surface of Black Mesa...
the new alien race introduced since Residual Point, looking like zombie HECU, with a much higher fire rate, and much more resistant. Their true allegiance is unknown, as they seems to be friendly towards Xen creatures but hostile to humans (scientists, HECU, black ops)
absolutely gross, but badass
Hey man are you using NPC code from They Hunger Trilogy to make they i see they file is "zgrunt.mdl"
I think it's just a convenient naming protocol.
hgrunt.mdl = Human Grunt
agrunt.mdl = Alien Grunt
zgrunt.mdl = Zombie Grunt
I definitely know them all to well. Very disturbing but awesome.
This image was like, "What the hell have you done to my HECU Marines?" But I called them, "Infested HECU Marines."
