|“|| The PsiCorps division has been tasked with destroying the Peacekeeper ICBM silo compound on the Vandenberg Air Force Base in California in order to prevent the United States from retaliating against the impending Soviet invasion.|
- Mission description
Operation: Peacekeeper is the first mission of the Act One Epsilon campaign, as well as chronologically the first mission of the entirety of Act One. This mission is focused on unit micromanagement, and sees the player sabotage the United States' Peacekeeper Intercontinental Ballistic Missile network in Vandenberg Air Force Base, California.
Proselyte, welcome to the future. Yuri has plans for you and all his followers in PsiCorps, and we shall help make the world into something grand. An operation of utmost urgency must be conducted - Russian Premier Romanov has decided to start the war, and when he makes this known to President Dugan, the Americans will no doubt launch Peacekeeper ICBMs at Soviet Russia. We promised the Premier a path to victory, and we shall follow through.
The rockets are being fuelled at Vandenberg Air Force Base in California. We activated a few of our agents there, and they are all you have to work with at the moment. Time is everything, as once those missiles launch, its over. But you have a secret power that Yuri has gifted us - the power to shape thoughts, and thus shape the currents of the future. Use them to make your way to the Base, and hit a few key points. With this, they will be defenseless.
Objective 1: Take control of the Allied Voyager.
Objective 2: Capture the Satellite Hack Center.
Objective 3: Infiltrate the Tech Center.
Locating the silos
Given that a face-front ground invasion would no doubt alert the Americans to a threat to their missile network, the Proselyte's agents, a few Adepts, utilized subterfuge as touring civilians to land in a nearby marina, where a small American military outpost with a Voyager transport for river crossings was stationed. One of the Adepts went to secure it, albeit with a bit of difficulty, particularly the American German Shepherds whom accompanied infantry in patrol duties constantly.
The Voyager and its occupant were used to transport the other agents, to the other side of the river, past a fortified beach where a few American forces could be mind-controlled as an escort. The Proselyte was informed of a Satellite Hack Center in the region that could be used to survey the immediate area and thus locate his target. Reinforcements came in the way of more Adepts and a team of Engineers that'd be used to control this Center, doubtlessly under guard.
The Proselyte was forced to rush his agents to the target, as he is aware the clock was ticking: the Americans weren't waiting for anyone's order to fuel the rockets and would be ready to fire the instant Dugan gave the final order. At worst, the rockets would be ready to launch in less than an hour.
Race against time
Managing to capture the Satellite Hack Center, the Proselyte locates the silo network, which was heavily defended and locked tight in, and thus realized only a skilled infiltrator could ensure an easy means for the Adepts to enter and prevent launch. Fortunately, one such infiltrator, but a single one, was in the area, but miles away, which added further complications. The PsiCorps was forced to fight through patrolling American forces, particularly priority threats like Humvees and Abrams tanks, to get to a small base garrison to locate and subdue the infiltrator. From there, and with most of the mission time spent, the Proselyte had to dash to the silos' location.
At the main garrison, where the silos were located, the PsiCorps had to mind-control a few key targets to eliminate any obstacle or threat that could kill the infiltrator – even authorized personnel would be found suspect if walking unannounced around the AFB premises. The main control center for the missile silos, a Tech Center, was infiltrated in the nick of time.
When President Dugan finally gave the order for the Peacekeepers to be launched, the PsiCorps adepts were in position to manipulate the missile command and keep the silos closed, which detonated along with the warheads. With the operation successful, the Proselyte ordered the Adepts to commit suicide to make sure that no traces of what happened could be linked with them, and while they give him a last message: "Yuri will find us."
|“|| Proselyte, your swift strike with limited personnel has saved the lives of thousands of our Russian comrades as they reach the shores of America unharmed. This invasion will set many things in motion, but it is only the beginning. Soon, the world will learn.|
- Yuri's message
Without the Peacekeeper ICBMs, the American forces were forced to withstand the brunt of the Soviet invasion with heavy losses, until then unaware of the existence of psychic powers or their use prior and during the invasion. With the Adepts' suicide, no immediate link was set and the Americans were led to believe of sabotage.
The connection would only be made with the Allied capture of a Psychic Beacon established in Soviet occupied New York. But, by then, enough damage would've been done for a turnaround, so much in the USA as in Europe.
The Proselyte himself was later assigned to lead the PsiCorps in supporting the Russian armored division's advance through Ukraine.
- The time limit before the Peacekeeper Missiles launch is different from each difficulty. On Easy, there is no time limit at all; on Normal, the countdown starts at 58 minutes and 20 seconds in-game, and on Mental difficulty, the countdown starts at 41 minutes and 40 seconds in-game.
- On Easy difficulty, only a single GI is defending the Voyager transport. On harder difficulties, there will be GI and Attack Dog patrols in the port.
- On Easy difficulty, the Spy is located near the Tech Satellite Hack Center. On harder difficulties, the Spy is at the opposite corner of the map.
- This entire mission is fully based on a segment of the Red Alert 2 intro where, when the ICBMs were about to be launched, Yuri mind-controlled the missile command operators and prevented the launch. However, it's also different as it seems the group of Adepts was responsible from preventing the Peacekeeper launch, not Yuri alone.
