Trivia

• This hat was speculated days before the game was even released due to the Heavy appearing on the icon for the Hat Trick achievement.
• The hat resembles a "Template:W", from the Template:W franchise, or a "Headcrab", a parasitic enemy from the Half-Life series.
• If you taunt with the Sniper's Kukri, Shiv or Bushwacka, the Sniper will very easily pull the parasite off of his head, before putting it back on.
• When the hat is shot after falling off of its owner, it will bleed which proves that the hat is, or once was, alive.
• Originally, the Heavy on the "Hat Trick" achievement icon had a beard.
• Like most promotional hats, the Alien Swarm Parasite does not count towards the recrafting hat blueprint.
• Since the MannConomy update, the Alien Swarm Parasite is more light and smooth than before.
