The Foehn Revolt is a paramilitary organization founded by the Chinese young genius Yunru created secretly with cooperation between China and Pacific Front that are dedicated to liberating the world which has since fallen under the control of Yuri's Epsilon Army through the Mental Omega Device. They consist of advanced units that are individually powerful but is expensive to produce.
The Foehn Revolt is added as the fourth faction in Mental Omega version 3.3 and is the only faction that is not from the vanilla and .
Before they were formally known as such after the Mental Omega War, the Foehn Revolt was originally supposed to be a technologically advanced army under China who uses completely separate equipment from the rest of the Soviet Union, which includes EMP, cybernetics, nanotechnology and weather manipulation technology. Development of weapons for the army is spearheaded by the young brilliant scientist Yunru under the assistance of Kanegawa Industries following China's occupation of Japan and the battle at Primorsky Krai, with research being centered at facilities in Xinjiang, Kashmir and Hidaka Mountains.
After the Epsilon Army, led by the enigmatic Yuri, started the Mental Omega War against both the Allies and the Soviets, Yunru realized that they are a major threat to mankind and the world upon her capture and escape from a PsiCorps underground facility in Afghanistan since their ability to control the minds of others is highly dangerous, for it is most likely why the Third Great War broke out and the cause of troubles faced by China near the end of the war, and at worst, could led into a global mind control scenario. Yunru subsequently decides to "do what must be done" by using all the technologies she had developed so far to stop Yuri and his Epsilon Army when the opportunity arises and gathering support from elements of the Chinese and Pacific Front forces.
At some point during the Mental Omega War, Rashidi, the leader of the Scorpion Cell which supposedly sided with Yuri, secretly approached Yunru and offered his cooperation along with – surprisingly – a MIDAS warhead quietly recovered during the Sino-Russian conflict to be used as a "fail-safe" measure against Yuri and his Epsilon Army in exchange for her protection and technology.
After interrogating General Wu during the invasion of Shanghai, the Russians became aware of Yunru's involvement in China's advanced weapons research, which led to the Soviet General commanding an army of Confederation troops to attack Yunru's main research facility in Kashmir, known to her as the "Home" Base, so they could claim the technologies for themselves. To make things worse, the Epsilon, who had found out about China's advanced weapons research, also sent two taskforces at the same time with the Soviet General to destroy the base. Just as the General's forces captured the Home Base's Mainframe however, Yunru detonates the MIDAS warhead she acquired from Rashidi earlier inside it, annihilating the Home Base along with the Confederation, Chinese and Epsilon forces, which successfully deprived the Soviets from Yunru's research and erasing any traces to her master plan, which is referred to as "the Revolt".
Following the destruction of the Kashmir Home base, Yunru brought along Chinese troops loyal to her and one of her masterpieces, a Centurion Siege Crawler, to escape from the Epsilon pursuers, who weren't fooled by her deception unlike the Soviet General. After the Centurion was destroyed by Libra. Yunru flees with Libra in tow, but just before the psychic could kill her, Yunru used her Immobilizer to tamper with Libra's Cerebral Amplifier/Suppressor, causing the psychic to went berserk and forces the Epsilon to bring Libra back to her senses, buying Yunru and her followers more time.
An artificial intelligence developed by Yunru, then known as VOLKNET, went online not long afterwards and noticed that its creator is in danger after her escape from the Epsilon, which prompts the AI to escort her out of Kashmir, away from the Epsilon who still persistently pursuing Yunru and the Chinese who have been alerted of a potential treason in their ranks due to the previous events. After leaving Kashmir, Yunru, VOLKNET and a Revolt sleeper cell in Kazakhstan hijacks an experimental supersonic jet as her getaway vehicle so she can reach the rest of the Revolt as quickly as possible since who knows when Yuri will carry out his ultimate plan to initiate a worldwide mind control.
Yunru later received news that China, who became increasingly concerned of an inside treason, had placed their forces on high alert and many of their facilities under lockdown, including the Kanegawa Industries facility in Hokkaido that assisted in with her research and holds blueprints for their particle collision technology, and along with the Revolt, heads to Japan to re-establish contact with the KI facility. After linking up with the KI facility, recovering the aforementioned technology and repelling the Epsilon forces who tried to destroy the Chinese-held Hokkaido Seismic Stabilizer, the Revolt finds out that Yuri is about to accelerate the progress of his ultimate plan, thanks to the all-out Allied invasion of the Epsilon's main base in Antarctica.
Upon reaching the Bering Sea, Rashidi, who had faked his death from the Epsilon, manages to link up with the Revolt as they are preparing for an attack by the Epsilon and their Russian thralls. Coincidentally, an Epsilon Rocket Launchpad allowing transport from and to space is also present in the Epsilon navy's base; the Revolt attempted to seize it as a backup escape plan should a worst case scenario happens. However, the Epsilon scuttled the Launchpad before it could be captured, making it highly unlikely for the Revolt to escape, much less survive, from the imminent global mind control. Ultimately the Revolt choose to press on, hoping to find a place far away from Yuri's main stronghold that could at least give them a chance.
The Revolt's march leads them to Point Hope, Alaska, one of the last American military fortresses that, under General Carville's leadership, managed to resist the Soviet invasion but are now controlled by Epsilon. Making use of most prototypes developed prior to and during the Mental Omega War and despite the initial psychic interference from Yuri's ultimate weapon, the Revolt was able to free the American garrison of Point Hope and rout the Epsilon forces with their help.
Through the Americans, the Revolt contacted Special Agent Tanya and Siegfried prior to their failed attempt to destroy the ultimate weapon, now known as the Mental Omega Device. Siegfried uses the old Chronosphere recovered from the Epsilon base to chronoshift the wreck of the Paradox Engine, which is crippled in the attempt to destroy the Mental Omega Device, into Point Hope, but are left behind and killed by the Epsilon Army. Upon arrival and meeting Yunru, Tanya agreed to help the Revolt.
From the notes left behind by Siegfried, Yunru and Rashidi realized that the "Foehn Theory" which involves the Paradox Engine's Time Freeze mechanism may be the one and only hope to survive the global mind control of the Mental Omega Device. The day after the recapture of Point Hope, the Revolt, now joined by all that remains of the Allies, prepared themselves for the final stand against the Epsilon's all-out attack against Point Hope while the Engine is repaired. Despite being seriously outnumbered as time passes, including from intermittent mass mind control from the Mental Omega Device, the Revolt managed to hold the line long enough for the Engine's repairs to be completed.
As all hope seems lost, Yunru overloads the Paradox Engine's Time Freeze, immediately turning the tide and putting Point Hope out-of-sync with the rest of the world. For the unforeseeable future, the Revolt, now formally known as the "Foehn Revolt", gathered their strength and build up their army with technologies they could develop and salvage so they could liberate the lost world when the time comes.
During the Mental Omega War, as much of their arsenal are still on prototype stages, under development or remains conceptual, the Foehn utilizes Soviet Chinese and/or Allied Pacific Front arsenal provided by Yunru's Chinese followers and Japanese collaborators, particularly elements of Kanegawa Industries who assisted her research, although they did use prototypes of their would-be main equipment on occasion, such as Knightframes, Gharials, Mastodons, Jackal Racers, Diverbees, Tarchia Cannons and Harbingers. The Revolt also fielded Iron Dragons and Future Tanks X-0, as well as controlling a limited number of Future Tanks Alpha.
Notably, the Foehn were inferior in the development of chrono technology compared to the Allies, as seen in the lack of the Experimental Warpshop and other advanced applications of chrono tech. The Foehn were only able to get a glimpse of chrono technology from the remains of the Paradox Engine.
The Foehn Revolt possesses the most advanced and futuristic technology out of all the four factions. As their military doctrine is quality over quantity, their technology focuses more on extreme survivability and firepower. Nonetheless, their unmatched forces individually compensate for their expensive costs.
Notable technologies utilized by the Foehn include:
- Wind manipulation technology – The signature technology of Foehn, first witnessed in Windbelts in the Kashmir Home base. The Revolt's mastery over wind allows them to create clean power sources that surpass all but the Nuclear Reactor, increase the speed of their units significantly, and harness nature's wrath to devastate their enemies. Foehn's air force makes use of wind manipulation to hover in the air, eliminating the need for an airfield to operate effectively. The Wings of Coronia specialize in this technology and dominate the battlefield with their Spinblade-boosted units and their unrivaled air force.
- Nanotechnology – Originating from China's research efforts, Foehn makes use of nanomachines to compensate for their limited numbers and resources. Nanites are used to repair Foehn vehicles, reprocess the remnants of fallen enemies to gain additional funds, construct and protect structures, and even transform infantry units into superior forms or even give them entirely new purposes. Nanoids can also be used offensively to "devour" enemies, and use the raw materials can be used to restore Foehn infantry. Last Bastion in particular is known for utilizing this technology to the full, such as their Bison and Mastodon tanks' natural ability to repair themselves in the midst of battle.
- Advanced artificial intelligence and robotics – The Foehn is superior when it comes to development of A.I., as demonstrated by the creation of VOLKNET and its subroutines, who function as tactical advisor and field commanders respectively. Aside from this, they are known to employ multiple robotic units that are immune to Epsilon mind control, from the basic A.I. of the Teratorn to the mighty Uragan, who has shown emotions such as anger. Outside of military use, the Foehn are the pioneers of supercomputers with security systems that makes them nearly inaccessible to enemies. In fact, Foehn can break through enemy intelligence databases with little effort, thus granting them signal jamming capabilities.
- Blackout technology - Courtesy of Pacific Front then likely passed on to the Foehn, blackout technology is reverse-engineered Chinese EMP technology, allowing the Foehn to disable enemy equipment in a pinch.
- Cybernetics – Based on Volkov's technology, most Foehn infantry aren't completely organic; they are augmented with cybernetic implants that enhance their performance in battle.
- Sonic weaponry – First utilized by Jackal Racers, it is the Revolt's prime technology against infantry hordes (particularly the Epsilon's due to their emphasis on such tactics). There is also one case of sonic waves capable of wreaking havoc on aircraft as a result of further experimentation, in the form of Haihead's Shadray. Other than sound crystals, pressure lances are also prominent in the Foehn arsenal to shatter armor with ease, as seen in their Lancer and Swordfish units.
- Plasma weaponry – By far one of the most devastating technologies realized by the Foehn Revolt, it has been put to great use by only the most advanced units that ensures total eradication of their foes. Such weaponry include plasma bombs, plasma cutters and even M.A.D. warheads.
- Particle collision weaponry – Developed initially by Yunru and her staff and with cooperation of Kanegawa Industries, particle collider-based weaponry has only been witnessed in their Iron Dragon and then Future Tank Alpha machines prior to the end of the Mental Omega War, and in their current incarnation, the Harbinger and Boidmachine epic units, but in both periods of time, these units are known to wipe out entire army divisions in the blink of an eye.
- Plasma railgun weaponry – A subclass of plasma weaponry, this technology boasts enormous anti-armor potential with the common flaw of a charging time before plasma railguns actually fire. This technology comes in many sizes, from the miniaturized armament of the Railguneer to the almighty Plasmerizer.
- Confusion rays – Designed to cause friendly fire scenarios among their adversaries, confusion rays are one of the more support-oriented Foehn technologies. Confusion rays are known to have both single-target and multiple-target variants, in the form of the Deviatress and Irritator respectively.
- Golden Rockets – Superior to generic rockets and Epsilon AROs, the highly explosive Golden Rockets are often employed against the fragile armor of enemy aircraft, though ground-to-ground Golden Rockets have been observed as well. The Last Bastion widely use this weaponry as seen in their Sweeper and Giantsbane units.
- Mechanized walkers – Fielded by Haihead exclusively, Foehn walkers look more human in appearance due to their bipedal attribute and were given more offensive roles than support ones, compared to their counterparts. Current applications of this technology include the Cyclops Walker and the Megalodon.
- Stun weaponry – A peculiar and somewhat uncommon element of Foehn's offensive arsenal, stun weapons render unfortunate infantry helpless to the Foehn's might. They may be deployed by aerial support, grid or specialized infantry.
- Main article: Haihead
Haihead appears to be Foehn's dedicated strike force, which uses maximum force for maximum effectiveness through powerful units such as Megalodons, Shadrays, Diverbees and the M.A.D.M.A.N. to deliver swift, focused and brutal attacks on enemy positions. With the help of Syncronins, it makes it even easier for Haihead to deliver fatal blows on enemy installations with ease.
Wings of Coronia
- Main article: Wings of Coronia
Focusing on aerial supremacy and rapid deployment, the Wings of Coronia can strike anywhere around the battlefield with their Pteranodons, Alanqa Skystations and Tarchia Cannons under the cover of the Harbinger.
- Main article: Last Bastion
The Last Bastion primarily focuses on defense, using durable and powerful units such as the Mastodon and the Gharial, the former of which are capable of repairing themselves on the field, aided by the Boidmachine that can strike enemies from across the battlefield.
- Several Foehn weaponry (confusion rays, stun guns and railguns) were previously owned by Epsilon in version 3.0 (though for the case of the confusion rays, they were known as chaos gas).
- Their name refers to the foehn or föhn wind, a type of dry, warm downslope wind in the downwind side of a mountain range.
- Many of their vehicles are named after prehistoric animals.
- Their symbol is based from the Consortium faction's logo (see right) in the discontinued Reign of Steel mod for .
- Thus, Holy_Master, the former main developer of the Reign of Steel mod, is credited with the original logo. In addition, Holy_Master is also credited with the voxels for the Megalodon and Cyclops Walker, as these units uses modified appearances of the original units from Reign of Steel, which are the Megalodon and Titan Assault Mech, respectively.
- The Foehn Revolt was conceptualized after the Nanofiber Sync's idea and mechanics became possible with Ares DLL.
- The idea of a 4th side had existed as early as version 1.2, and it was originally planned to become available in version 2.0, but was never implemented until version 3.3.
- Speeder claimed to have the idea of introducing new sides, one of which has "a grey/purple color scheme and air manipulation technology", back when he was a  It is probably not coincidental that Foehn has "a grey color scheme and air manipulation technology". player.
