The Crossbow is particularly effective against Ichthyosaurs, since it is both powerful and capable of firing underwater.In multiplayer, a zoomed shot to the head will instantly kill a fully healed and fully charged player. If attacking marines or Vortigaunts, aiming for the head results in a one hit kill, even on the hardest skill levels. The Crossbow is effective against most enemies, but is best saved for tough, slow moving enemies or those who are unaware.The only exception is one crossbow that is found in a specimen locker lying next to a dead security guard in the chapter Questionable Ethics. However it appears to be lethal to most other targets.Īpart from the scientist's comment, it is unclear as to whether this neurotoxin is really a non-lethal tranquilizer, but just at such a concentrated dosage to be fatal to human sized targets, or if it is in fact a lethal drug developed for use against Xen creatures by experimenters nor is it clear whether the neurotoxin has an instantaneous effect or if it is the force of the impact that kills a target.īecause the Crossbow was used only for unique tasks at Black Mesa, such as knocking out Ichthyosaurs (due to its ability to fire under water), ammo for it is scarce, and neither soldiers nor security guards are ever seen using one. Its effects on Ichthyosaurs (which stop and twitch before losing consciousness upon being struck by several darts) support this. These are fed one at a time into the firing mechanism, which utilizes a high-tension wire to launch the bolt while a scope fixed on top allows the player to zoom in on his or her target.ĭuring Apprehension, a scientist refers to the crossbow as a "tranquilizer gun", while an HEV Suit audio clip (not heard in-game, but included in the game's files) identifies the crossbow's ammunition as "neurotoxin-treated crossbow ammunition". Its ammo consists of five feathered bolts in a magazine. The construction is modeled upon modern composite bows. After the chapter, it can be reacquired in the chapter Questionable Ethics, after Gordon had been stripped of his weaponry upon capture by HECU Marines.

In Half-Life, the Crossbow is first acquired by the player during the chapter Apprehension, where it can then be used to kill an Ichthyosaur.
