Devlon Industries is best known for producing basic armor models that can withstand a variety of environmental extremes such as cold, heat or toxic exposure. They also market a complete line of military grade weapons. Devlon Industries produces the following armors: Explorer Armor, Liberator Armor, Thermal Armor, and Survivor Armor.
If any member of the squad is wearing Survivor, Explorer, Liberator, or Thermal Armor, it will negate the timer on environments with Level 1 environmental hazards and slow down the timer on Level 2.
In Mass Effect 2, Devlon Industries manufactures the M-92 Mantis Sniper Rifle
Powerful sniper rifle able to take out most targets in a single shot. Incredibly accurate at long range, but rate of fire is slow. Effective against armor, but weaker against shields and biotic barriers. Manufactured by Devlon Industries, the Mantis is primarily used by police and planetary militia groups. The prevalence of kinetic barriers has made this weapon less popular with the military, but it is used more frequently in the Terminus system where these defenses are less common. Has great damage and accuracy with near instantaneous hit, offset however by its small amount of extra ammo that can be carried.
In Mass Effect: Revelation, the manufacturer of Stinger pistols is given as being the Ahial Syndicate. The name 'Ahial' may derive from the Kitab al-Hiyal, also known as the Book of Ingenious Devices.
