Larval Extract
OBJECT
A substance derived from the secretions of Antlion larvae, larval extract has many purposes and uses.


In Half Life 2: Episode 2, Gordon Freeman (Character) ventures deep into an antlion colony with the help of a Vortigaunt (Concept) ally to find a chamber of unhatched larvae with which to produce the extract. The larval extract is apparently a powerful energetic medium, allowing Vortigaunts to manipulate the Vortessence, which they use to save Alyx Vance (Character) from a mortal wound she receives from a Combine Hunter.
