Game information


"It's your old friend, deadly neurotoxin. If I were you, I'd take a deep breath. And hold it."

The Neurotoxin Generator is located in a large industrial area in the Aperture Science Enrichment Center, near the Employee Daycare Center.


The Neurotoxin Generator is a massive cylinder housed within a large room. Eight large hoses attached to it allow the gas contained within to be distributed through the Aperture Science Pipe Network to any location throughout the facility. Its storage capacity is presumably large enough to cover the entire facility, which is how GLaDOS killed all the employees.

The Neurotoxin Generator is the second objective in Chell and Wheatley's plan to nullify GLaDOS' defenses. After disrupting the turret production lines, Wheatley and Chell make their way to the generator, which Wheatley then attempts to "hack". As he has no idea what he's doing, Chell has to disable it by using portals and a Thermal Discouragement Beam to sever the hoses. This causes the pressure within the container to drop to "Dangerously Unlethal levels". The container then implodes and falls apart. Subsequently, a vent on a nearby wall breaks open, drawing in Chell and Wheatley.


  • Despite the Neurotoxin Generator being completely destroyed by Chell and Wheatley early on in the game, Wheatley is still able to use neurotoxin in the final battle.
  • Neurotoxin is in fact nerve poison, meaning it could paralyse or instantly kill a person.
  • Originally, in Portal the neurotoxin would kill Chell after five minutes, however when she takes GLaDOS' word of advice and steps into a trap in Portal 2, it takes the neurotoxin only several seconds to kill her.
