For the glory of Tech!”
The Reaver Movement was founded many decades before 2197 in the Midwest. They were raiders at first who found a military cache in the Midwest and started to create a religion dedicated to the worship of technology and everything around it. Sometime after, they established a headquarters in the former city of Newton, Kansas, where Reaver scientists began to examine and produce technology and weapons. They are very different of the Brotherhood of Steel, since they feel technology has an important religious significance and have religious beliefs in various technology-related fields. They are also more aggressive and have kept their likeness to raiders, acting like them when they come close to getting new technology.
Proof of how great their dedication is demonstrated by the fact that just after learned about the destruction of a humanoid robot in Junction City around 2198, they are immediately came to the town to retrieve the parts and established a compound outside, preparing for battle without worrying about whether anyone could head them off. Here the Warrior and his squad met them for the first time. They were launching probing attacks against Junction City for the parts, but they were killed and the Eastern Brotherhood of Steel recovered all of the humanoid-robot parts instead.
Sometime later, a reaver delegate came to Bunker Delta of the Eastern Brotherhood of Steel, bringing news that a large Calculator's robot force has all but annihilated the main camp of the Reaver Movement in Newton. The delegate called on the motion of the Eastern Brotherhood of Steel for assistance in the defense of the city, and above all, to save the four reaver elders: (Albert Lamore, Rodger Gaire, Glenda Close and Tobias Peste), who barricaded themselves in various locations throughout the city.
Normally, the Eastern Brotherhood would gladly allow one enemy to destroy another, but the reavers had something to offer in exchange – a pulse rifle prototype developed by the Reaver Movement thanks to robot pieces that they had been able to scavenge, that has a devastating effect on electronics, which makes it an effective weapon against the Calculator's robots. They agreed to give the Eastern Brotherhood both a prototype of this weapon and instruction on its workings if Newton and the four reaver elders were saved.
After the Warrior's squad liberated Newton, several reavers decided to join the ranks of the Eastern Brotherhood of Steel in order to fight the "Menace from the West", the army of the Calculator. Although the action of the liberation of Newton established official contacts with the Reaver Movement, the Eastern Brotherhood elders were a little skeptical. Other reaver survivors of Newton were temporarily placed in internment camps to await a further turn of events – set them free or restrict them to labor camps.
They are lead by the four reaver elders and have a structure similar to a traditional government with politicians, a chief of the army, a medical division, a science division, et cetera, but religious classes are also important in the Reaver Movement, like priests. Also, the priest is the only reaver office that can be held in conjunction with the other classes, like scientist-priest. They are extremely numerous, and a group of about forty reavers can be seen in Junction City just to get one item of technology and patrol the Midwest. Sometimes just one reaver is found, but generally they are in groups of two to eight, supported at times by super mutants of Gammorin's Army.
The ambassadors care for the reaver's people and their religion, acting like ministers. The leader of the ambassadors, and one of the four reaver elders, is the "1st Ambassador", Albert Lamore in 2197, his function is comparable to a president of the Reaver Movement. The leader of the reavers army is the "General and joint chief of staff", also one of the four reaver elders: Rodger Gaire in 2197. They give the orders for all major military projects and are assisted by captains in the field. Their medical leader and another reaver elder is the "Chief of medical division" (also called First Doctor), and is Glenda Close in 2197, who is in charge of medical research as well as practical applications of medicine in the field. The leader of the scientific research and the last reaver elder is the "Chief of science division" (also called Chief of military science projects): one Tobias Peste in 2197.
Also, they have priests allowed to perform the sacred rites of the Reaver Movement and acting as a mediator between the reavers and the reavers' gods. They also have holy visions about prophecy or technology, fanciful or not, that sometime take shape after in Temple-Laboratories, the reaver workshops. They generally perform a period of fasting, permitting them to have a better contact with their gods.
Technology is everything for the Reaver Movement, seeing it as sacred, searching for the spiritual enlightenment of science. Knowledge is divine for them and they don't hesitating to give courage in combat with citing the greatest invention of man or the scientific theory, like "for the glory of the transistor" and "by the spirit of Counter-Electric-Motor-Force!", also calling each other brothers, like a great family. They believe in a thing called the "current flow", connecting them between the spiritual world of technology and the real world.
They have and revere many gods called Tech-Gods – mostly based on electrical units or pre-War technology components - their domains being related to their function. The know Tech-Gods of the Reaver Movement are:
- Electric Father of Creation, the creator of everything
- Heavenly Ampere, the god of vision (comes from the unit of electric current)
- His Capacitance, a kind of guide for the Reaver Movement
- Holy Ohm, the god of resistance (comes from the unit of electrical resistance)
- Panasonica, lord of the Eternal Assembly Lines of Panasonica (comes from the corporation Panasonic)
- Saint Di Ode, the god of protection (comes from a diode, an electrical component)
- Saint Sony, the god of vision (comes from the corporation Sony)
- Satansoft, the god of evil technology and lord of the Tech-Underworld (comes from Satan and Microsoft)
- Be'alza-Gates, the acolyte of Satansoft (comes from Beelzebub and Bill Gates, founder of Microsoft)
Like many religions, they believe in places similar to Hell and Paradise. The reaver Hell, the place of all evil technology (like the Calculator's robot) is named the "Tech-Underworld" which has a large electric current traversing it called the "Styx River", an obvious reference to the Greek underworld of Hades. It's the domain of Satansoft, a derogatory reference to Microsoft, (also called the "Dark One" by reaver priests) and his acolyte Be'alza-Gates, whom controls hostile technology. For them, the Calculator's robots are the hydroelectric fiends of Satansoft, also called hell spawns. The reaver Paradise, where the reavers and especially the fighters killed during an honorable battle go after life is named the "Eternal Assembly Lines of Panasonica", the domain of Panasonica.
While Reavers revere technological instruments and weapons, they think hostile technology against them, like the Calculator's robots, are possessed by a evil god named "Satansoft" and are their creature, a "Satansoft's creature". Each piece of recovered hostile technology are surnamed "evil part". They also have something called the "Holy Multimeter", allowing them to get answers on something, but it's only available for consultation by reaver priests.
Relations with the outside
Before the official contact with the Eastern Brotherhood of Steel, the Reaver Movement was hostile towards anyone except Gammorin's Army, who patrolled together sometimes to cover an area too far west for Gammorin's Army. As zealous worshipers of technology and their past as raiders, they act like them when they come to getting new technology, attacking anyone making their way through them with technologies. Apart from them, they see others as pagans without interest (even the Eastern Brotherhood of Steel).
They all wear atypical armor created with woven steel cables with plates of interlocking steel mesh encased in cloth panels, like the reaver banding and greater banding. They are technologically strong in cybernetics enhancements and surgical augmentations, often use for their body, mostly scanning sensor that allow at least to sweep an area of twenty feet, detecting even a person who is sneaking. They are also known to use enhanced eye sight, hand surgical implants, central processors and valve-tube augmentation.
Reavers often carry high-tech weapons and their scientists have shown great intuition, being able to invent new technological things like weapons. Their arsenal includes:
- 5.56mm CZ57 Avenger minigun
- 7.62mm DKS-501 sniper rifle
- 7.62mm Vindicator minigun
- Glock 86 plasma pistol
- M79 grenade launcher
- Pulse grenade
- Wattz 2000 laser rifle
- Winchester P94 plasma rifle
- Even after Newton and the four are reaver elders saved by the player, the reavers encountered in the wasteland during random encounters will remain hostile to them.
- "Technology is not dead, technology is life!"
- "Holy Ohm, help us resist our enemy damage."
- "Heavenly Ampere, help us flow into the enemy's defense."
- "May St. Di Ode protect me in battle!"
- "What would St. Sony do?"
- "The Tech-Gods will punish you."
- "Eat my tech!"
- "You're about to go off-line!"
- "Give me your technology you pagan scumbag!"
- "Kill them. Take their Tech. Save your souls."
- "I run with the speed of a gamma!"
The Reaver Movement appears only in Fallout Tactics.

- John Levis: "Pleased to meet you, warrior. I'm John Levis, Mayor of Junction City.
You'll have to excuse me, but we're having a bit more excitement here than we're used to. With that robot attacking, and now those Reavers bandits trying to get the robot parts, well, I'm getting pretty damn fed up.
I know what you're after, so let's cut to the chase. My city is an independent! We take care of ourselves and we won't march to the Brotherhood beat. But we can't hold off those Reavers for much longer. Those tech freaks pack some advanced firepower, so I'll make you a deal.
Kill all those religious tech bastards and I'll give you the robot head. It's more trouble than it's worth, anyway. You'll have to look for the other pieces yourself. I have a city to run."

- Dekker: "Greetings, warrior.
Your next mission will bring you to Junction City, a mid sized town that has refused to form an alliance with the Brotherhood. Their independent posture has been recently reinforced by their victory over one of the robots late last night. Our Elders are quite curious how such a battle could be won, considering the lack of heavy weaponry involved. This is a riddle whose answer might be paramount for victory. See what you can find out.
More important than this riddle is the retrieval of the robotic parts from the scene of the battle. We must understand how our enemy works in order to neutralize it and any robotic remnants might hold the key.
Understand that the Reaver Movement has been launching probing attacks against Junction City. Our Elders believe that they are also searching for robotic pieces. Considering the Reavers zealously worship technology, their involvement comes as no surprise. Try forging a deal with the town's mayor - robot parts in exchange for protection from Reavers.
We have one last task for you as well. Our senior mechanic, Cooter, died recently when he triggered an explosive booby trap on a retrieved Interceptor vehicle. His apprentice lacks the cognitive ability to fully assume the role, and in times like this, we can't have any malfunctioning vehicles involved during a high-risk mission. Intelligence reports that Junction City's mechanic is top notch, and might be persuaded to join the Brotherhood's cause. Find this mechanic and inform her of the wondrous opportunities the Brotherhood can offer.
You have your orders. Dismissed."

- Dekker: "At ease , Warrior. I have mixed news to give!
A Reaver delegate arrived earlier today bringing news that a large robot force has all but annihilated the main Reaver camp in Newton. The Reaver's numbers have been devastated by relentless attacks and will soon be destroyed unless we intervene. Normally, the Brotherhood would gladly allow one enemy to destroy another, but the Reavers have something to offer.
The Reaver Movement has developed a new type of weapon based on robot pieces that they've been able to scavenge. This weapon is called an EMP device and it has a devastating effect on electronics. It is this weapon that is allowing the Reavers to survive a mass robot attack, but for them it is still "too little, too late."
They have agreed to give the Brotherhood both a prototype of this weapon and instruction on its workings in exchange for rescue of their four highest-ranking officials in Newton's Junk City.
This might be the edge we're looking for against the robots. Bring back that prototype, Brother. You will be supplied with a map to Newton. Rendezvous at the extraction zone with all four Elders and they will be transported via APC and armored escort back here.
