Caustic Nox Gas Trap

A toxic cloud that turns the battlefield into a deadly, suffocating maze for any who dare enter.

The Nox Gas Trap is a signature piece of tactical equipment utilized by the Apex Legend known as Caustic, whose real name is Ion Ashford. This device functions as an area-denial tool designed to release a thick, yellow-green cloud of toxic gas upon activation. In the chaotic arena of the Apex Games, it serves not merely as a weapon but as a psychological barrier, forcing opponents into uncomfortable positions or flushing them out of cover through sheer chemical pressure.

Lore & Background

Within the lore of the Apex Games, Caustic's traps are feared for their unpredictability and persistence. Unlike simple explosives that detonate instantly, the Nox Gas Trap creates an expanding zone of danger that lingers, forcing teams to alter their movement patterns entirely. The gas is potent enough to strip away shields rapidly, leaving players vulnerable to follow-up attacks. It embodies Caustic's desire to trap his enemies in a nightmare of their own making, reflecting the suffocating atmosphere he feels whenever he confronts his past.

In Their Own Story

The air in the abandoned warehouse grew heavy and acrid as the yellow-green cloud billowed from the small canister on the floor. A squad of three rushed toward the corner, expecting a clear path, only to choke on the invisible poison that now filled their lungs. Their shields flickered and died under the chemical assault, forcing them to scramble backward into the open, where Caustic waited with his rifle raised, watching them cough and stumble in the haze he had created.

Reader's Guide

The Nox Gas Trap is a throwable device designed for area denial and crowd control. When deployed, it emits a dense cloud of toxic gas that expands outward from the point of impact.

Any Legend entering this zone suffers continuous damage to their shields rather than direct health loss initially. If a player remains inside long enough, their shield will be completely depleted, leaving them vulnerable to fatal attacks from opponents outside the fog.

Caustic places these traps strategically in choke points, doorways, or behind cover to force enemies out of safe positions. They can also be used defensively to block off retreat routes or to flush out campers hiding in tight corners.

The gas persists for a short duration before dissipating, requiring players to time their movements carefully. Mastering the placement of these traps is essential for any team looking to control high-traffic areas during a match.
