With the Soviets beginning their march through Europe, PsiCorps must subvert a heavily guarded choke point, softening up the European Alliance's defense and granting the Russian tank divisions safer passage into Western Europe.
- Mission description

Operation: Accelerant is the second mission of the Epsilon Act One campaign. Like the first mission, Peacekeeper, this is a micro-intensive mission, in which the player must depend in unit management and mind control constantly to accomplish the objectives, here.


The American "Empire" is now occupied with a gigantic invasion. As Yuri foresaw, the Europeans have refused to come to their defense - they will realize their folly only later. For now, other tasks remain. High Command at home has moved onto another part of their plan - to reincorporate the parts of our country that were stripped off of us after the last war.

To complete this first phase, we have to retake all our former SSRs - while the Central Asian republics won't last for long, Ukraine, the United Baltic Republic, and Poland will not be so easy. These nations have guarantees from America, and also defense partnerships with the European Alliance. Their people have gotten used to their freedom, and won't give up so easily. Furthermore, the commander of the operation is not experienced - he is heading straight through the Verecke Pass. This region is infested with Ukrainian and Euro loan forces, and is riddled with Artillery Bunkers. The tank columns moving through will be torn to shreds. Thus you have been selected by Yuri to lead an operation to help him. Take out the Artillery Bunkers and otherwise support our comrade, and Ukraine will fall.

We need to do this for another reason - PsiCorps independence, and even funding, have long been criticized by the High Command. We can't risk a loss of Yuri's already fragile position.

Objective 1: Capture or destroy Artillery Bunkers.
Objective 2: Support Russian armored forces.
Objective 3: Destroy Euro Alliance forces.
Note: If the Russians lose, the mission is failed.


A small PsiCorps team under the Proselyte's command airdropped behind enemy lines along with a small Soviet infantry team as escort, right as the first wave of Soviet forces tried advancing through the Pass, but were shortly obliterated not only by enemy numbers, but by the Artillery Bunkers, as well. The gravity of the situation as well as the Soviet Commander's impatience meant the Proselyte had much less time than he had when he had to deactivate the Peacekeepers in America.

Fighting heavy enemy resistance, especially close to the Bunkers, the Proselyte figured that, instead of destroying them, he could turn the Bunkers to in turn soften enemy defenses at the pass below. The greatest issue, however, was that he had no Engineers given to him, so he had to resort "convince" the ones already in the field to his side. The first two Bunkers, close to a bridge connecting both sides of the pass and also near an Allied base, were captured, but some of PsiCorps' escort had to remain behind to defend them from European reclamation attempts. The 'replacements' had to come from mind-controlled Allied forces.

On the other side of the bridge lied not only garrisoned troops near a farmhouse, but also a small European outpost with a Barracks in it. The PsiCorps Adepts nearly strained themselves fighting through it, but they had managed to capture the Barracks with a spare mind-controlled Engineer, ensuring a supply of infantry that could fight through the defenses to the other Artillery Bunkers. On their hand, the Artillery Bunkers the Proselyte managed to capture had been at work devastating European positions whom didn't have air support to neutralize the enemy threat.

By then the second wave had arrived and, despite renewed artillery support, it was also defeated. The Proselyte was warned that the Soviet Commander would make one last attempt to push through and would mass up forces for it. If that wave was equally routed as the other two, the Soviets would have to abort, meaning a defeat for PsiCorps. With limited time, the Proselyte used all forces from the Barracks he captured to push through the defending Allied Forces and captured the remaining Artillery Bunkers, whom were working around the clocking softening up as much European forces on the pass as they could. Along the way, PsiCorps spotted a reserve of unmanned Allied vehicles that the Proselyte immediately ordered be commandeered, as he prepared his subverted forces for a suicidal plan - Even if the final Soviet advance managed to come through the Pass, he doubted there'd be enough strength to fight through and destroy the Allied base he discovered earlier, since it guarded the Pass' only landslide access to the upper cliff.

The Proselyte's forces, despite the advantage, waited until the third final wave arrived to start their advance on the Allied base, and even with the Allied vehicles they captured, the final fight was all but easy. Fortunately, they managed to break through and hold the access long enough for the last of Soviet forces to pass through and finish enemy resistance. Stragglers would be mopped up hours later.


Thanks to your efforts, our Russian friends have broken through the choke point with minimal losses and are set to invade Eastern Europe. They should not require assistance from us for some time. Now, we have our own plans to fulfill.
- Yuri's message

The capture of Ukraine meant not only the reclamation of a former territory, but also allowed further access towards Western Europe. Pretty much like it happened in Vanderberg, PsiCorps also pulled out and allowed the Soviets to fight their own war.

One important thing to note is the level of distrust concerning PsiCorps despite their proven success time and again by Soviet Command. This would be further explained in the next mission, when PsiCorps would depend on a terrorist leader and engineering genius, Rashidi, to obtain Mobile Construction technology, one of the many sacrifices PsiCorps had to make if they were ever to get off the ground.
