M240 Incinerator

Lore & Background

In the void between stars, standard kinetic weaponry often proves useless against the chitinous resilience of xenomorphs. The M240 Incinerator emerged from Weyland-Yutani labs as a contingency for when containment breaches turned into massacres—prioritizing total biological annihilation over precision. It is an instrument of area denial, built to melt through armor and incinerate nests where bullets would only scatter eggs or draw more enemies. Yet, deploying open flame in the vacuum-sealed corridors of a colony ship is a gamble; the weapon consumes oxygen as fast as it burns flesh, risking hull integrity and turning a rescue mission into an atmospheric firestorm.

In Their Own Story

The airlock hissed shut behind them, sealing out the hiss of the hive. The corridor ahead was slick with acid and shadow. 'Contact!' the sergeant screamed, raising the M240. A low, guttural chittering echoed from the ventilation shaft above. Before the creature could drop, the engineer triggered the weapon. A roar of orange fire erupted from the nozzle, filling the narrow passage with blinding heat. The alien shrieked as its carapace blackened and curled, dissolving into ash before it hit the deck. But the flame didn't stop; it licked at the walls, melting the bulkhead plating as the oxygen levels on their HUDs began to plummet.

Reader's Guide

The M240 Incinerator operates as a pressurized delivery system for thermite gel and oxidizer, converting stored fuel into a sustained jet of fire hot enough to carbonize tissue instantly. While effective against soft targets—facehuggers, chestbursters, or clusters of eggs—it is a blunt instrument in the hands of the unprepared. Tactical use demands extreme environmental awareness. The flame consumes oxygen rapidly and can melt bulkhead plating or ignite volatile ship gases. Because of these collateral risks, the M240 is reserved for sterilization protocols where retreat requires leaving no biological trace. It mandates a dedicated operator trained in fire suppression and structural safety to prevent turning a containment breach into a catastrophic hull failure.

Did You Know?

• Marines colloquially refer to the system as a 'flamethrower,' though its gel-based fuel distinguishes it from older terrestrial models.
• Its primary tactical advantage lies in vaporizing targets before they can bleed, preventing acidic blood contamination of the environment.
• The external fuel tanks are heavy and bulky, often requiring a harness that limits mobility for sustained fire capability.
• Due to the risk of depleting oxygen or igniting ship gases, it is considered a weapon of last resort.
