The Snark, also known as the Squeak Grenade,[1] is an enemy which doubles as a biological weapon. It can be found in Snark Mines / Snark Nests, and will attack the player when the mines are tripped. However, the nests can be picked up and snarks can be used as weapons that can be thrown towards enemies.


Snarks are small, beetle-like creatures with four legs, a single green eye, and a thick, dark red, segmented shell. They are social and highly territorial, making nests and protecting them at all costs. The fleshy nests themselves are about the size of a road sign, and dark green with translucent red pods and four claw-like branches on each corner.

When their nest is threatened, Snarks will leap out and charge at their intruder, bouncing around madly and biting with their sharp beaks. These bites are powerful, doing as much as 10 points of damage each and easily crippling the player if they are not careful. To add insult to injury, a snark will explode about 20 seconds after they start attacking, spraying acid everywhere.

The Snark emits a high-pitched squeak with each bite, which gets higher and higher in pitch the longer it stays in its 20-second "attack mode" before finally exploding.

A Snark nest.

The player can obtain an egg sack containing 5 Snarks which can be used as weapons. While held, Snarks have an unlimited lifespan, but still show aggressive tendencies (as two comical idle animations show one animation with the Snark struggling in Gordon's hand, and the other with it snapping at Gordon as he teases it with his finger). Once thrown, the Snark's twenty-second "attack mode" begins, and it will immediately charge at the nearest living thing and attack it. If there is nothing for them to attack, they will turn around and attack Gordon instead (which is why the player should always be sure to throw them from a higher vantage point).

In multiplayer deathmatch games, Snarks provide a useful way of distracting other players (particularly multiple players), facilitating escape or a means of a more leisurely kill. It is not uncommon for a player to be seen running through the map while being chased by a pack of Snarks.

Xen forces have learned to use Snarks to their advantage. In the chapter "Forget About Freeman!", there are Snark Mines that hang in the air with the use of webbing. When shot or tripped, the lasers on them will release snarks to attack the player and slow down the player's progress, acting like biological tripmines.


When faced with a Snark, a single swing of the crowbar is enough to kill it, though their speed and size can make this a daunting task. The shotgun, with its wide spread, is a better choice of weapon as it allows the player to take them out from a distance (to avoid their acid blast) and kill several Snarks at once, should they be faced with two or more. Usually, the MP5 is the most preferred and arguably the most suitable weapon to wield against groups of Snarks.

The Hivehand (also known as Hornet Gun) is also a great choice because of its infinite ammo and characteristic that its primary fire will fire hornets(also known as thornets) that can easily track them down and kill them. The ultimate best solution, however, is to run away as soon as you throw it.

It is possible to avoid snarks by hiding on a high enough ledge and either shooting them from there, or waiting until they explode. As snarks cannot jump very high, they are unable to get up and attack.

The player can carry up to 15 Snarks at a time, and can release them all at once to cause a tremendous amount of chaos. Snarks will attack most Xen aliens, making the weapon very useful in the later levels of Half-Life, and if a Snark does not sense a nearby target they will turn against whoever released them.

This is also pretty good against a Voltigore, if you can't use displacer cannon or M249.

Behind the scenes

  • The Snark nest has unused "walking" animations.
  • An item similar to that of the Snark was to appear in Half-Life 2, but instead of a Snark, the player could use the Brickbat to throw Headcrabs.

  • When viewing the viewmodel, the player is holding the Snarks' nest, though this is not actually seen in game. When using the High Definition Pack, the nest cannot be seen.
  • The HD Snark nest model seems to have a piece of ribcage attached to it, suggesting the Snark either makes nests from its kills, or are scavengers who nest in corpses.
  • Half-Life: Opposing Force's CTF game mode has a replacement for the Snark, which is a Penguin with a grenade tied to its back. These behave similarly to the regular Snarks, with some differences, as they cause more damage but are slower in handling.
  • In some speedruns, players will throw a Snark below them and can somehow jump on top of the snark and continuously while the Snark will attempt to bite the player (if there are no nearby enemies). This allows players to reach great heights or even areas outside of the map.
  • A Snark contained inside of a jar appears at the beginning of Half-Life: Alyx, by feeding it, the player gets the achievement "Good Grub".
