Decades in the making, finally, Yuri's vision of the world is nearly complete. With the Proselyte's guidance, the Creation has matured. There is only but one direct threat to Yuri's Tower left, and the weapon against it is in the hands of Epsilon. The final stage of the race against time itself begins.
—Mission description

Operation: Babel is the twelfth and final Epsilon Act Two campaign mission.

Briefing

Yuri's Message: "If you've received this message, it means I'm dead. To carry my psychic legacy, you must know the truth and this is the only truth I can give you now. Decades ago, I whispered words of persuasion as an Adviser to Stalin, fueling his drive for world domination, while in the conquered nations my own PsiCorps searched for more of us, those gifted with terrific powers. Having lost grasp on the world, I've been forced back into hiding by the Allies until their influence has weakened and a puppet premier has been appointed. I managed to make my way back into the Kremlin and continued my search, gathering subjects from all around the world. Our powers kept growing, but eventually I realized it was all futile; with all my knowledge I could not understand the reason why we came to be. For years I've worked persistently to further my research and my own capabilities, but my mind was not enough - I couldn't learn the truth alone.

Then, the impossible happened, and I understood. With the minds of the entire world to command, and all of its knowledge to conquer, I would be able to.

The technology works, Libra is a living proof of that - the prototype hivemind I created from and by connecting the psychics I managed to find, channeling and reinforcing their powers. That's why for every psychic killed, she lives through a death, which turned her unstable. But death is inevitable and the hivemind must learn to suffer through it. With her experiences, she will make the foundation of this psychic network and once the Mental Omega Device is activated, Libra will learn and speak all the words of the world - if she can handle them, that is.

And if she does, I hope you reach the truth in my stead, Proselyte."

Events

The Chase

Libra descends at the Southern Cross regiment's base with an Omega Storm unleashing

As Rahn and the Epsilon Headquarters taskforce sent to defend the Mental Omega Device arrived from the Southern Cross regiment's rear, Libra herself made a dynamic entry into their base via a paradrop and ravaged their base with an Omega Storm, destroying a large portion of it in the process. Unprepared for their arrival and completely caught off-guard by the female commando's devastating potential, the European Alliance's elite force was decimated in a matter of minutes - supported by the greatly enhanced Libra herself, the Headquarters armored division pushed towards left of their starting position and mopped up the remains before Rahn authorized an establishment of an outpost from where their initial adversary's base once stood.

Though the Headquarters forces accompanying Libra weren't spared from heavy casualties, the damage was done. The Allies' upper front had completely fallen, allowing the Epsilon to shift their main focus towards the bottom side as they rapidly dug into their positions and began bringing more forces into the area.

The loss of the Southern Cross regiment did not dissuade the Allies as they continued to intensify their attacks via chronoshifted reinforcements and support from the Pacific Front's Boomerang regiment. The Proselyte was advised to get Libra to the Mental Omega Device as soon as possible - the urgency became even more apparent when the last Mental Dynamo was destroyed and the Tower itself was no longer invincible. The deactivation of the barriers for the massive construction and the Ganzir Defenders protecting it gave the Allies the cue to throw even more airstrikes at it, though they suffered heavy casualties doing so.

Knowing that the Tower was durable but not indestructible without the psychic shielding protecting it, Libra continued slaughtering anyone that dared to stand between her and the device that would make Yuri's vision a reality. After many bloody skirmishes, she reached the foot of the Mental Omega Device and wasted no time entering it. Now it was only a matter of time before it could be fully charged and bring the entire world under 'one mind'.

The Final Countdown

Libra's entry into the massive construction initiated the charging sequence of the Mental Omega Device - within ten minutes, it would be activated and all remaining resistance across the globe would be inevitably neutralized. All the remaining Epsilon forces in the area dug in and braced for the endless waves of Allies that charged at the plateau from all directions - although all they needed to do was to hold their positions and defend the Tower until it was ready, this was easier said than done. The Allies sent waves after waves of aircraft to relentlessly bombard the Tower, and each subsequent hit it took would delay its activation. As the Epsilon Construction Yard in the core base was destroyed, the Proselyte was unable to fortify the area with additional defenses or construct replacement buildings - with only a Barracks and War Factory at his disposal, he gave the orders to deploy as much infantry and armor as possible. Casualties did not matter as all he needed to do was wait patiently and the Mental Omega Device would take care of the rest.

Rahn's taskforce finally received their Mobile Construction Vehicle and commenced the establishment of a new base in the upper right sector of the battlefield. The HQ commando promised that the base would be handed over to the Proselyte at a later point, and reminded him to send some reinforcements if necessary. The Proselyte's advisor stated that this was an optional objective, as the protection of the Mental Omega Device was their primary task. More reinforcements arrived just right of the site in the form of HQ armored vehicles, including an Aerial Fortress Irkalla and some Hazequads. These additional forces were used to break down more Allied lines in their immediate sector before they moved towards the Antarctic hinterland to assist in the defense.

Thankfully, the last four Ganzir Defenders made the task of defending the site far easier - their long-ranged dissolver beams melted approaching infantry and vehicles as if they weren't even there, and any aircraft unfortunate enough to fly into their ranges were vaporized in seconds. An additional air armada consisting of yet another Irkalla soon arrived from the bottom side and wasted no time reinforcing the faltering defense around the Tower. The Allies had already eliminated all the defensive structures, destroyed the last production buildings, and what remained of the original defense were the Ganzirs and some infantry.

Yuri's Tower is ready for activation! The voices of the entire world will be united! Through our Beacons and Amplifiers, all will become one in the great Hivemind!
—Epsilon EVA, after the Mental Omega Device is fully charged

The ten minutes seemed like an eternity for the Epsilon, but the Allies had ultimately failed to destroy the titanic construction within that time frame - now with the Mental Omega Device fully charged and ready, the entire world would know no more free will, but only Yuri's will. All Epsilon forces could finally breathe a sigh of relief as they finally reached the end of this brutal war while finally emerging from the ruins as victors at long last...

The Nexus

WARNING - Chrono anomalies detected! You are in the Paradox Engine's range!
—Epsilon EVA, detecting the Paradox Engine activating its Time Freeze

...or so they initially thought. Moments before the Tower could unleash its psychic waves that would blanket the entire Earth, the Paradox Engine activated its Time Freeze and froze the entire battlefield and every non-Allied entity - including Yuri's Tower itself. The Proselyte could only watch helplessly as his battlefield control was taken offline and the reality was apparent - now that the Mental Dynamos were no longer protecting the Mental Omega Device, it could freely move in and destroy the Tower with no resistance. Once the battlefield controls were restored, almost all remaining Epsilon units and structures, including the Ganzir Defenders were destroyed.

However, the unexpected happened - Libra herself was unaffected by the Time Freeze as the Chrono Backpack she possessed made her immune to its effects. Racing against time as the last of the Epsilon forces were still frozen and were systemically being eliminated by the Allies, the Proselyte took command of Libra and destroyed any Allied units that dared to venture near the site. She also noticed the two Allied commandos emerging from the tunnel entrance that led to the underground fortress, but she paid no heed to them - it would take the duo a while before they could reach the plateau. Matters took a turn for the worse as the Allies started summoning Lightning Storms on the Tower itself, damaging it significantly but it still managed to hold - for the time being. But the real question was this: where was the Paradox Engine?

Libra received her answer as the Paradox Engine, escorted by a sizable armada of Warhawks, Cryocopters, and Thor Gunships advanced from the upper left, wiping out what little Epsilon resistance remained with minimal effort. Even the two Irkallas could only slow down the Allied advance as they too eventually fell to the overwhelming onslaught. The PsiCorps heroine immediately chronoshifted herself forward and confronted the air armada, shooting down as many of the escorting aircraft as possible while making sure to stay far away from the prism cannons that the Engine possessed. A handful of anti-air forces had also arrived from the upper side and while they too were wiped out, they managed to moderately damage the Paradox Engine with Libra.

Though the Epsilon failed to destroy the Paradox Engine, they were able to force it to retreat as it had prematurely activated the Time Freeze while not at maximum power, which depleted all of its remaining energy reserves. This bought some much-needed time for the Epsilon to recollect themselves and plan their next move. It was clear to them that even with Libra now at near-max potential and all the weapons they had available from their insidious arsenal, they were still no match for the Allies' trump card despite their forces and resources dwindling with each casualty they took. They needed a new approach, and quickly - once the Allies fully recharged the Engine, it would go after Yuri's Tower again and the Epsilon weren't sure if they could stop it a second time.

The Stalemate

Both the Allies and the Epsilon hastily withdrew the bulk of their forces to reestablish the bulk of their forces and numbers. In particular, even though the European Southern Cross suffered immeasurable casualties at the hands of Libra and the HQ vanguard forces, they still possessed a strong presence in the area and regrouped with the main Allied Commander's forces and the Pacific Front Boomerang Division. The Epsilon sent MCVs to the core base where the Mental Omega Device was located and to the bottom right plateau where their original airbase was located, while additional ones were sent to the front to establish a perimeter against the Allies.

The Proselyte's advisor informed him of a tactic to sabotage the Paradox Engine in some way to allow their forces a better chance to destroy it. Through studying the Supercharged Paradox Battery in a previous operation, they learned that the Allies were chronoshifting their forces from a pocket dimension connected to the Paradox Engine itself. The Allies were also chronoshifting their MCVs back to this supposed dimension when they suffered critical damages; the Epsilon planned to exploit this for their own tactics by infiltrating their Construction Yards with Infiltrators. Once this was achieved, the Infiltrators themselves would be able to access the pocket dimension and once within, they would attempt to find the means to sabotage the Paradox Engine's main weapons - the prism cannons.

Reinforcements of a certain size allowed Epsilon to easily resist Allied attacks and take advantage of Libra's power such as Blink and Omega Blast to break down Allied fortifications in front of their bases, and the Infiltrators sneaked into the designated Construction Yards not long afterwards. As they were about to be chronoshifted to the Pocket Dimension along with these Construction Yards, which were to be packaged as MCVs, Epsilon sent their mind-controlled Soviet and Allied troops on standby to raid the Allied upper left main base and the lower left Boomerang regiment base.

The raid caused the Allies to move all remaining living forces below the battlefield. Seeing that the Allies had temporarily lost the ability to actively harass Epsilon positions, the Proselyte turned his attention to the Infiltrators' activities.

The Weapon

One of Paradox Conductors that stores inside the Pocket Dimension of the Paradox Engine

Once inside the Pocket Dimension, what the Infiltrators need to do is yet another stealthy sabotage mission - enter three Paradox Conductors and close them to disable the Paradox Engine's prism cannons. The advisor believed that stealth sabotage moves, which helped Epsilon build a business, will also be an important step in its final success. First, the Infiltrators manipulated the large number of Warp Circuits at the entrance to give them a symmetrical shape, then two of them went to manipulate the two Control Panels in the hallway, avoiding any Attack Dogs and Robot Tanks, allowing the third Infiltrator to enter the room where the first Paradox Conductor was located.

The next trick is more complicated: the remaining Infiltrators hid themselves in the containers temporarily in order to cross the corridor, and quickly exited the corridor after the Attack Dogs passed through the containers. Then they found another set of puzzles controlling the gates to the deep chambers. These puzzles were more complex than the previous one, and it took the Infiltrators a lot of time to do so. After solving the puzzles, one of the Infiltrators came to the second Conductor's room, while the other came to a hall with four Control Panels. These Control Panels were the key to unlocking the gates that blocked another Infiltrator, so the Infiltrator in charge of the action began another cracking job: reacting quickly to the information displayed by the Control Panels. He didn't want his companion to permanently lose the chance to enter the second Conductor because of the guards that were triggered by mistakes, so he and the Proselyte, who was assisting the conductor, focused their attention on the information displayed quickly. Fortunately, this cracking operation was also successful, allowing the second Paradox Conductor to be safely infiltrated.

The last Infiltrator had one last step to complete. He used the Shadow Ring generator to evade the Attack Dogs that were quickly patrolling the entrance to the next room, and noticed that the next room had a large electrical grid. He carefully observed the grid's regulated move, managed to reach the opposite room where the cryocoolant was stored, and placed the bomb, ahe detonated the bomb when he crossed the grid again. As expected, the Robot Tanks guarding the entrance to the next room were used to monitor the cryocoolant storage room. After confirming that there were no other threats, the Infiltrator entered the final area.

A random 10-digit password was required to open the gate to the last Conductor room, so the Infiltrator went to the nearby Kanegawa Assembly to extract the password. After carefully writing down the extracted numbers, the Infiltrator entered the password at the Control Panel in front of the door, entered the last room, and quickly broke into the last Paradox Conductor. The continued work of these Infiltrators in the Pocket Dimension made it impossible for them to witness Epsilon's final victory, but they played a very important role in what was to come.

The Giant

The success of infiltration brought the Prime Proselyte back to the battlefield. The Allied forces had assembled in the square area in front of the core base, and Epsilon had transferred all active forces that can be adjusted to the square. What the Epsilon Army needed to do is stop the Allied counterattack at all costs and destroy their Paradox Engine.

Leave the rest to me, Proselyte. You've shown me the path.
—Libra

While previous actions by the Infiltrators had crippled the Paradox Engine's firepower and ability to teleport additional reinforcements on which the Allies had relied, Epsilon decided to be fully prepared. Libra used a lot of terminus gas to enhance her combat performance and began to observe the course of action of the Allies. The Prime Proselyte found that the Paradox Engine was still advancing towards the Tower in a severely weakened state. In order to prevent the Allies from using some last resort to threaten the Tower, he sent Libra to stall the advance of the Paradox Engine, and let other soldiers led by Rahn drag the Allied Army and Air Force advancing after the Paradox Engine.

Libra uses her power to stop the Paradox Engine at all costs

As expected, the Paradox Engine quickly activated Time Freeze after being critically damaged by Libra, immobilized all Epsilon members except her. Libra told Prime Proselyte that the final blow to destroy the Paradox Engine's thrusters only needs to be done by her. In order to prevent the Paradox Engine, which has already approached the Tower, from using unknown means again, Libra decided to concentrate her psychic energy and not use the custom darts to continue to attack, but to use the psionic lightning current to continue to fire at the Paradox Engine. Using this extreme attack method, Libra quickly incapacitated the Paradox Engine.

However, the about-to-crash Paradox still went straight towards the Tower, causing serious damage to it before falling in the other direction.

The Truth

The Paradox Engine was finally confirmed to have crashed on a high ground near the core base, and Rahn led his active forces to hunt down the remnants of the Allied forces, including Siegfried. Although the Tower was badly damaged in the impact, it was still functional; Although the mentor Yuri had sacrificed in Moscow's efforts to contain the Soviets, he reduced the pressure the Epsilon Army may face in this battle. The Epsilon Army had won an absolute victory. The only thing they have to do now is to get Libra back into the Tower and activate the "Hivemind".

No nations will ever rise against each other, and no one will threaten you again. But if it somehow comes to it, I'll be here, ready to protect you in your Tower. The damages from the crash will delay its activation, but you can still do it.
—Rahn

Rahn returned to the square to report the pursuit of the Allied remnants to Libra, and then said that if the war came again one day, he would definitely guard the safety of Libra and the Tower. With everyone's support voices, Libra returned to the front of the Tower from the square and met the Prime Proselyte. She said that she would give the Epsilon Army, and the world, the "truth" she had been always searching for. The Prime Proselyte acquiesced to her by not saying a word. Finally, Libra entered the Tower without any fear and began carrying her next duty.

It is time to become.. of one mind.

Aftermath

Despite the setbacks, all has transpired according to Yuri's vision - at last the entire world shall speak the common language, and all of its knowledge will be within our reach. Now you have everything you need to continue his legacy, Proselyte. The end is the beginning.
—Battlefield report

Yuri's vision is achieved. As the Tower reactivated thanks to Libra, it began to slowly mind control everyone that isn't aligned to the Epsilon cause. Across the globe, the still remaining Soviet and Allied forces make their last stand which either they perish or succumb to the effects. However not all can handle the effects of the mind control caused by the Tower and likely perished, it is also noted that there are still people who are highly resistant to it forcing Epsilon to hunt these individuals down and sent them to the Grinder along with other "failures" within Epsilon's own ranks. With that, the Proselyte succeeded his master and continue Yuri's legacy.

Unfortunately for them, one group did managed to avoid such fate and due to a certain device made themselves isolated from the rest of the world. Elsewhere in Africa, Malver continues his solo mission as he kills Epsilon soldiers left and right even in the absence of Rashidi. Plus, some reports from remote zones said that there are still resistance gathering in Alaska.

Along with it, the Proselyte hears a whisper who apologize to them and saying that she unable to bear it anymore and wants to rest.

Easter eggs

SPOILER
  • In Stage 1, if the player does not use any of Libra's abilities (Omega Blast, Omega Storm and Gravity Field) during Stage 1 of the mission, they will be commended for their tactical ingenuity once she is safely brought to the Mental Omega Device.
  • In Stage 2, find and kill three polar bears that appear in three areas with abnormal red tiles will get a small amount of extra power supply.
  • In Stage 3, if the player manages to shoot down all of the Paradox Engine's escorting aircraft during Stage 3 of the mission, the Proselyte's EVA will inform them that the Allies' superweapon is now an army on its own. This must be done before the Engine is critically damaged and retreats to the left side.
  • In Stage 4, build 6 Epsilon War Factories, 6 Aerodomes, 3 Pandora Hubs and deploy 2 War Rigs, and some hidden reinforcements including 7 elite Speeder Trikes will be given.
  • In Stage 5, there are 7 Control Panels with the color of Red, Yellow, Green, White, Cyan, Blue, Purple at the upper right corner of the map. And there are four places on the map with patterns of 1, 2, 4 and 8 respectively, each number has a corresponding light color. You need to hack each control panel in the order of representative colors of number 1 to 15.
    • For example, If 1 is Red, 2 is Green, 4 is Blue, 8 is Red,
      and Yellow=Red+Green, Purple=Red+Blue, Cyan=Green+Blue, White=Red+Green+Blue,
      so we have 1=R, 2=G, 3=1+2=R+G=Y, 4=B,
      5=1+4=R+B=P, 6=2+4=G+B=C, 7=1+2+4=R+G+B=W, 8=R, ..., 15=1+2+4+8=R+G+B+R=W.
      So we should hack into the control panels in the following order: RGYBPCWR...W (...)
  • If the easter egg in Stage 5 is completed, up to four elite Salamanders will be a part of the last defending forces during the Allies' final gambit to destroy the Mental Omega Device, they are not controllable by the player however. Amount of Salamanders depend on how much previous easter egg sections have been cleared.
