'''Mind worms''' are horrible [[Monsters|creatures]] with dangerous psychic powers. They come in two varieties: weaker hatchlings and more powerful boil.
Mind worms attack from afar with psi blasts, causing 1 damage to the head and prolonged [[confusion]]. This may not seem too bad, but given how your head tends to have very little [[HP]] and that mind worms only need to sense you through their [[ESP]] to kill you even through walls, they are a priority target. However, as [[tin]] or [[lead]] [[helmets]] block ESP, wearing one will make all mind worms a non-threat.
If mind worm boil gets next to an enemy, it will attempt to burrow into their skull and lay eggs. Hatchlings will later spew forth from the victim's head.
