A common headcrab.

{{#set:Prerequisite=None |Benefit=+3 bonus on Jump checks. }} An ever-present threat within the confines of our dystopian cities, the headcrab preys upon our flesh. They are iconic to the threat we face. They represent the immediate danger that the Combine poses to us. The headcrab is not so much a biological weapon, but rather a weapon to break our spirits and leave us shattered, so that when they manage to couple with our heads we will have long since been ready to die.

Summary::A headcrab is a predatorial Xenotheric species, whose natural hatching grounds lie within the vast plateaus of Xen. They are however extremely able and adapt to other environs easily, having been injected into Earth's ecosystem with startling resistance to Earth pathogens, and impervious to radiation or toxic wastes. A headcrab is a small, quadrupedal creature that does not possess a body; its four legs are attached directly to its head and are positioned to allow quick jumps while impairing general movement. It is about 18 to 30 inches in size and weighs 4 to 10 pounds.


Headcrabs hunt as they have always hunted, using their silence and stealth to attempt and surprise humanoid victims. It is believed that they have a heightened tolerance for pain and miss the instinct that would motivate personal survival. It is also believed that headcrabs are able to communicate with other headcrabs through scents that only their olfactory senses can detect (it is encouraged that any DM using this resource in their games make personal decisions about the headcrabs' behavior for balanced gameplay; making one attract others may lead to more action, but may pose a great risk to low level characters).

Lunge (Ex): Headcrabs can attack their victims with a lunge attack. The headcrab pounces its target, foregoing conventional reach. This gives any melee attack that it makes a maximum reach equal to 5 + ½ the creature's Jump modifier (10 feet under normal circumstances). If a headcrab hits with its lunge attack, but fails to couple, it lands in the square adjacent to the target after dealing its damage. If it simply misses, it may immediately move away from its target as a 5-foot step, regardless of any movement it has made that turn.

Attach (Ex): If a headcrab hits a Medium or smaller creature of Humanoid type with its lunge attack, it attaches to the creature's head unless it succeeds on a DC 13 Reflex save. A headcrab that critically hits a humanoid creature can instantly attach. A headcrab that is attached to another creature is effectively grappling that creature and may incite a head-couple. Headcrabs have a +16 racial bonus on grapple checks when attached. An attached headcrab may be struck or shot with a weapon, or grappled itself. The save is Dexterity based. Of course, only one headcrab can attach to a certain humanoid creature at a time. Helpless creatures cannot prevent a headcrab from attaching.

Favored Enemy (Ex): A headcrab naturally preys on humanoids of size medium or smaller. Against such creatures it receives a +2 competence bonus on damage rolls.

Head Couple (Ex): An attached headcrab will attempt to couple with the head of its victim. If it starts a turn while coupling the head of a Medium or smaller humanoid creature, it scores an automatic hit that becomes a critical hit if it succeeds on a confirmation roll. When a humanoid creature dies while being coupled by a headcrab, or when a sufficiently intact corpse is coupled later on, a headcrab can extend its neural impulses through the corpse's nerve system through microscopic receptacles on its beak and legs, taking control of it as a neonate 'headcrab zombie' in 1d4 minutes.

Overwhelm (Ex): Headcrabs gain a bonus of +1 to their attack roll for each other headcrab that targets the same creature. For example, if three headcrabs attack the same creature, they all get a +2 circumstance bonus to their attack rolls. Bonuses gained from this special ability can never exceed +4, even if more than five headcrabs attack the same creature simultaneously.

Feats: Headcrabs get Improved Initiative and Skill Focus (Jump) as bonus feats.

Skills: Headcrabs get a +12 racial bonus to Jump checks and are always considered to have made a running start for the purpose of jumping (even although they cannot run). Their instinctive stealth tactics also lend them a +8 racial bonus to Move Silently checks.


A headcrab may be selected as a familiar. It grants its master a +3 bonus on Jump checks. Also, if the master is below 4th level in the class that gives him the familiar, any headcrab zombies produced instead has Hit Dice equal to the level of that class.

The headcrab portrayed above has invested 4 skill points in Jump, and 2 skill points each in Hide, Move Silently, Listen and Spot.
