Your Allies

Although Zombie Stress is specifically a lone ranger, fight your own battle type mod there are some allies around which will help you fight your battles.

	The Combine Although your enemy in Half Life 2, they have chosen to fight a long side you in your battle against the Zombie hords. Though you only really see their corpses lying around, in the first map you get to fight a long side them so long as they are alive.
	The Turrets Although at first they are against you. When you flick a switch they turn to be on your side. A valuble tool against fighting the masses of zombies that approach you. Plant them well and they will cover your back.
