The '''Sacktick''' is a parasite Synth{{fact}} enemy cut from ''Half-Life 2''.

==Overview==

The Sacktick was to be a macro virus, about the size of a dog, created by the Combine, and resembling real-world WikipediaAntlion|antlions.Anonymous Valve employee on ReferencesValve_employee_emails Sackticks It was to be delivered by missile-like pods in numbers, generally to soften an enemy position before an assault. Its mouthparts were to be able to splay open, as part of a threat display. In addition, it was to make a clicking buzzing noise while bobbing its body up and down against the surface it would be attached to. The sack (the black growths on its both sides) was to be kept curled under the tick's body. Once fed, the sack was to unfurl behind the legs and be dragged behind the tick. Its only known depiction shows the creature bearing markings similar to that of the Gunship, said to denote delivery vehicle and task group.

The Sacktick was to seek out organic hosts, on which it would feed and use as food for the next generation of ticks – multiple organisms of this species would leap onto a person and attach to them, draining them of blood until they died. In this way, a small number of ticks dropped into an enemy stronghold were to multiply and create a great number of individuals.

As heard in the playable Development of Half-Life 2 game|''Half-Life 2'' leak sound files, Sackticks were originally to be launched at the ''Borealis (cut ship)|Borealis''. Sackticks were to be unable to resist low temperatures, and Odell was to explain to Gordon that he was able to defeat them by shutting off the Borealis' generator, and let the ship ice over.Playable Development of Half-Life 2 game|''Half-Life 2'' leak files

==Behind the scenes==
As speculated by a Valve employee, the Sacktick was cut during the development of ''Half-Life 2'' probably because of the change of the game's design, and the fact that the creature might have turned out not to be "fun enough to preserve". It is known that a model for it existed, and was used as a placeholder for crows during their development.

==Fate==

The Sacktick's delivery by missile-like pods is the only thing that made it into the Half-Life 2|final game, recycled as the Headcrab Shell.
