Npc headcrab black

Entity description

Black headcrab - click to enlarge

Black headcrabs, upon biting the player, temporarily reduce the player's health to 1. They are best used in tandem with other melee NPCs like regular headcrabs to make fighting more intense. However, it is risky to group them near NPCs with ranged attacks, as the player will die very easily. In fact, many players are conditioned to kill black headcrabs first because of the threat they pose compared to other enemies.

Commonly found in groups covering a single host poison zombie which hurls its parasite cargo towards the player, they can make a formidable foe so should be placed carefully. Killing the poison zombie will not necessarily kill any of the headcrabs it is carrying, much less all of them (the sole exception may be AR2 secondary fire energy balls). They are also quite resistant to fire and will attack while burning.
