It is a creature that attacks people, trying to latch onto their head. Upon doing so, it begins to take control of their motor functions, turning them into zombie-like creatures that appear to retain their intelligence and emotions despite lacking the ability to express them in this state. The sequel, ''[Half-Life 2](/source/Half-Life_2)'', feature multiple new Headcrabs such as fast and [poisonous](/source/poisonous) ones, each creating different Headcrab Zombies. The ''Half-Life'' development team was split on making ''[Half-Life: Alyx](/source/Half-Life%3A_Alyx)'' (2020) a [virtual reality](/source/virtual_reality) game, with the fact that the Headcrabs would be jumping at the player being both an upside and downside depending on the perspective. They initially intended to feature fast Headcrabs and zombies, but opted to not do so when they saw that players struggled too much to deal with them. Critics identified this appearance as particularly terrifying, stating that the inclusion of the Headcrabs justified making the game on a virtual reality platform. The Headcrabs have been generally well received, considered by multiple critics to be a particularly scary and effective monster. Of particular note was their ability to [take control of people's bodies](/source/take_control_of_people's_bodies), with one critic commenting that the execution was more akin to ''[The Thing](/source/The_Thing_(1982_film))'' (1982) rather than the zombies from [George A. Romero](/source/George_A._Romero)'s films. ==Appearances== The Headcrab debuted in ''[Half-Life](/source/Half_Life_(video_game))'' (1998) as an enemy that attacks protagonist [Gordon Freeman](/source/Gordon_Freeman) and other surviving humans by leaping at them and biting them. Headcrabs first appear when a portal is opened, sending various interdimensional beings into the game's world and sending the Black Mesa lab into chaos. Throughout the game, the player encounters bodies with Headcrabs on their head, some of which becoming animated and attacking living people. In the sequel, ''[Half-Life 2](/source/Half-Life_2)'', the Headcrab and Headcrab Zombies return in a similar capacity. Headcrabs can be found in various environments, and the main antagonists, the [Combine](/source/Combine_(Half-Life)), who have taken control of the world post-invasion, have been attacking civilian and resistance groups by shooting rockets with Headcrabs in them to infect the population. Other Headcrabs appear, including a fast one and a poison one, the latter of which can put Gordon in serious danger if bitten. The character [Isaac Kleiner](/source/Isaac_Kleiner) manages to debeak a Headcrab, keeping it as a pet called Lamarr. Headcrabs also appear in ''[Half-Life: Alyx](/source/Half-Life%3A_Alyx)'', a [virtual reality](/source/virtual_reality) game.{{citation needed|date=January 2026}} Fast-moving Headcrabs and Zombies were originally considered for inclusion, but were removed due to tests finding that they moved too fast for players to properly react.{{cite web |url=https://bloody-disgusting.com/interviews/3609928/interview-valve-discuss-vr-accentuates-horror-half-life-alyx/ |title=[Interview] Valve Discuss How VR Accentuates the Horror in ‘Half-Life: Alyx’ |work=[Bloody Disgusting](/source/Bloody_Disgusting) |last=King |first=Andrew |date=March 24, 2020 |accessdate=January 31, 2026 |archive-date=August 18, 2025 |archive-url=https://web.archive.org/web/20250818082150/https://bloody-disgusting.com/interviews/3609928/interview-valve-discuss-vr-accentuates-horror-half-life-alyx/ |url-status=live }} Outside of the ''Half-Life'' series, the Headcrab makes multiple cameo appearances.

When designing ''Half-Life: Alyx'', the team was in two camps, with the ability for a Headcrab to jump at the player's face in virtual reality being the reason some supported it and others opposed it. When designing the Headcrab in this game, it was designed to have a percentage chance for it to miss in its leap, thinking this made them more fun to interact with.{{cite web |url=https://www.rockpapershotgun.com/valve-half-life-alyx-interview |title=We talk Half-Life: Alyx with Valve in "the meanest interview ever" |work=[Rock Paper Shotgun](/source/Rock_Paper_Shotgun) |last=Castle |first=Katherine |date=March 26, 2020 |accessdate=January 31, 2026 |archive-date=August 2, 2025 |archive-url=https://web.archive.org/web/20250802133911/https://www.rockpapershotgun.com/valve-half-life-alyx-interview |url-status=live }} ==Reception== The Headcrabs have received generally positive reception, identified as a series mascot due to existing merchandise.{{cite web |url=https://www.rockpapershotgun.com/best-monsters-pc-games |title=A Few Of My Favourite Monsters |work=[Rock Paper Shotgun](/source/Rock_Paper_Shotgun) |last=Smith |first=Adam |date=February 3, 2016 |accessdate=January 31, 2026 |archive-date=January 26, 2025 |archive-url=https://web.archive.org/web/20250126055534/https://www.rockpapershotgun.com/best-monsters-pc-games |url-status=live }} ''[Kotaku](/source/Kotaku)'' writer Levi Winslow regarded encountering Headcrabs in ''Half-Life'' as among the most frightening moments in video games; they felt that the name itself was rather frightening, but the sight of it lunging for the player's head disgusted them. They found it particularly disgusting that, once it latches onto a person, it begins to take over their motor functions.{{cite web |url=https://kotaku.com/best-horror-halloween-silent-hill-tlou-dead-space-game-1849686683/3 |title=13 Frightening Moments In Games That Live In Our Heads Rent Free |work=[Kotaku](/source/Kotaku) |last=Winslow |first=Levi |date=October 21, 2022 |accessdate=January 31, 2026}} ''[Rock Paper Shotgun](/source/Rock_Paper_Shotgun)'' writer Adam Smith regarded the Headcrabs as among his favorite video game monsters, stating that they have many of the traits of the best monsters, including being small, hiding in dark spaces, leaping at people's faces, and the ability to turn people into zombies. In particular, the weaponization of Headcrabs in ''Half-Life 2'' struck Smith, feeling that it represented a "credible extension" of the Headcrabs' role from ''Half-Life''. He found the Poison Headcrabs to be particularly frightening, stating that he could not talk about them without "lift[ing] my feet onto the chair" out of anxiety of being bitten by one. Describing the Headcrab as "shamelessly ripped off" from the [Facehugger](/source/Xenomorph)s from the ''[Alien](/source/Alien_(franchise))'' series, ''[GamesRadar+](/source/GamesRadar%2B)'' writer Alex Avard felt that it was one of the most terrifying aliens for a multitude of reasons, including its leap attack, what happens if it latches onto a person's head, and the Headcrabs found in Ravenholm.{{cite web |url=https://www.gamesradar.com/which-alien-scares-the-bejeesus-out-of-you/ |title=Which alien scares the bejeesus out of you? |work=[GamesRadar+](/source/GamesRadar%2B) |last=Avard |first=Alex |date=May 24, 2019 |accessdate=January 31, 2026 |archive-date=August 10, 2024 |archive-url=https://web.archive.org/web/20240810085809/https://www.gamesradar.com/which-alien-scares-the-bejeesus-out-of-you/ |url-status=live }} ''[Vice](/source/Vice_(website))'' writer Patrick Klepek felt that the Headcrab was an iconic enemy known by people outside the ''Half-Life'' fandom, stating that due to it becoming more familiar, it became less intimidating, citing the fact that it was made into a plush. He felt that the Headcrabs in ''Half-Life: Alyx'' were responsible for making Headcrabs scary again, stating that it being a virtual reality game made its attacks that much more frightening. He felt that the Headcrabs being scary served as proof of how well ''Alyx'' works as a video game.{{cite web |url=https://www.vice.com/en/article/half-life-alyx-review-vr-gamble-paid-off/ |title=‘Half-Life: Alyx’ Is Scary as Hell, and Proves Valve’s VR Gamble Paid Off |work=[Vice](/source/Vice_(website)) |last=Klepek |first=Patrick |date=March 23, 2020 |accessdate=January 31, 2026 |archive-date=November 19, 2025 |archive-url=https://web.archive.org/web/20251119070005/https://www.vice.com/en/article/half-life-alyx-review-vr-gamble-paid-off/ |url-status=live }} ''[Dread Central](/source/Dread_Central)'' writer Justin Wood felt similarly about the virtual reality technology, stating that the sight of Headcrabs jumping at the player created "visceral reactions", as well as making him uncomfortable to hear them creeping around.{{cite web |url=https://www.dreadcentral.com/horror-gaming/491455/why-did-it-have-to-be-jeff-half-life-alyx/ |title=Why Did it Have to be Jeff?

He felt that the zombification they induced was evocative of [John Carpenter](/source/John_Carpenter)'s ''[The Thing](/source/The_Thing_(1982_film))'' rather than [George A. Romero](/source/George_A._Romero)'s zombie films. He found the ''Half-Life 2'' iteration of the Headcrab Zombies as particularly shocking, citing how the Headcrab Zombies have muffled screams from the host and, when killed, the Headcrab falls off dead, revealing a face recognizable enough to see the "haunted look of them realizing their fate in their final moments remains". He argued that the zombies of ''Half-Life'' served to show the humanity of the Headcrabs' victims. He also believed that the Headcrabs in [Ravenholm](/source/Ravenholm), particularly the Poison Headcrabs and running zombies, represented how big of a threat Headcrabs could be.{{cite web |url=https://www.dreadcentral.com/editorials/492147/monster-mania-half-lifes-hellish-headcrabs/ |title=Monster Mania: Half-Life’s Hellish Headcrabs |work=[Dread Central](/source/Dread_Central) |last=Krieger |first=Jay |date=April 3, 2023 |accessdate=January 31, 2026 |archive-date=August 17, 2025 |archive-url=https://web.archive.org/web/20250817073529/https://www.dreadcentral.com/editorials/492147/monster-mania-half-lifes-hellish-headcrabs/ |url-status=live }} ''[Edge](/source/Edge_(magazine))'' staff felt that the running zombie was a memorable video game monster, believing that its "demented wail" was among the most chilling noises in video games.{{cite web |url=https://www.gamesradar.com/making-of-half-life-2/ |title=The making of Half-Life 2: Valve takes us behind the scenes of its narrative masterpiece |work=[Edge](/source/Edge_(magazine)) via [GamesRadar+](/source/GamesRadar%2B) |date=November 22, 2019 |accessdate=January 31, 2026 |archive-date=November 8, 2025 |archive-url=https://web.archive.org/web/20251108073738/https://www.gamesradar.com/making-of-half-life-2/ |url-status=live }} The Headcrab Zombies were described as "walking tragedies" by ''Rock Paper Shotgun'' writer Alec Meer, believing that they represented the horror of what zombies are rather than what zombies can do to the player. He appreciated how the game managed to escalate from questioning why the "weak, tiny" Headcrabs were attacking people, to seeing corpses twitching, and finally to seeing someone who was probably still alive but with no control of their body.{{cite web |url=https://www.rockpapershotgun.com/ties-tragedy-half-lifes-zombies |title=Ties & Tragedy: Half-Life's Zombies |work=[Rock Paper Shotgun](/source/Rock_Paper_Shotgun) |last=Meer |first=Alec |date=May 27, 2010 |accessdate=January 31, 2026 |archive-date=January 13, 2025 |archive-url=https://web.archive.org/web/20250113210157/https://www.rockpapershotgun.com/ties-tragedy-half-lifes-zombies |url-status=live }} ''GamesRadar+'' writer Ashley Reed found it harrowing to discover that the Headcrab Zombies were still alive and begging for help.{{cite web |url=https://www.gamesradar.com/scariest-video-game-easter-eggs-and-where-find-them/ |title=The scariest video game Easter Eggs and where to find them |work=[GamesRadar+](/source/GamesRadar%2B) |last=Reed |first=Ashley |date=October 31, 2014 |accessdate=January 31, 2026 |archive-date=April 5, 2025 |archive-url=https://web.archive.org/web/20250405110952/https://www.gamesradar.com/scariest-video-game-easter-eggs-and-where-find-them/ |url-status=live }} ==References== {{reflist|2}} {{Half-Life}} Category:Fictional monsters Category:Fictional parasites Category:Half-Life (series) characters Category:Video game species and races Category:Video game characters introduced in 1998 Category:Zombies in popular culture Category:Fictional extraterrestrial species and races Category:Fictional characters with body or mind control abilities --- Adapted from the Wikipedia article [Headcrab](https://en.wikipedia.org/wiki/Headcrab) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Headcrab?action=history)).
