Trivia

• 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; this seems to reinforce the hat's description that it is merely along for the ride and not hostile.
• 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.
