Mental Omega Wiki

The Allies set up the experimental Gladius Defense System, capable of intercepting and destroying ICBMs before they impact. The Soviets launch a massive assault to destroy the system in a bid to conquer the United Kingdom once and for all.
—Mission description

Operation: Sunlight is the twelfth and final Allied Act One campaign mission.


It has come to this. Germany has finally fallen after a MIDAS destroyed the Black Forest, and France is next, to be attacked from both sides by the Comintern forces. It's unfortunate, but it seems we couldn't fully trust the Euro Alliance. We've learned that, for a while now, the Euros and the Pacific were simply taking what they could from us, technology such as our Mercury. Much of your expeditionary forces were used in a gambit to provoke the Comintern into revealing locations of the remaining MIDAS warheads, of which there were two, according to reports from the forces who have fallen trying to take them down. Yes, once they too lost control of Mercury's lasers, massive Euro operations were being conducted deep into Russia to try to destroy the launchers as a last resort, but they failed. It turns out the Chronosphere was dysfunctional, as agents unknown had placed an EMP charge inside, and so the Soviets previously managed to delay its development by destroying finished parts somewhere else. With the Lab and the Chronosphere mere debris, our chances are slim.

Still, we have one. The scientists affiliated with the Paradox Project were chronoshifted to England. The Soviets intend on conquering it in one fell swoop by striking the capital with their last MIDAS. They would be successful if not for a secret British project that they jealously refused to share: the Gladius Defense System, an ICBM interceptor, though inferior to our laser technology. The problem is that while effective, it has limited range, thus the multiple emplacements. If even one unit is to fall, it will be enough for a MIDAS to get through. Survive, and fight, for the battle of Britain awaits you.

Objective 1: Protect the Gladius System units from Soviet attacks.
Objective 2: Destroy the Soviet bases.


Defending the Gladius ABM System

Allied Commander's base

Working with a base, a large force of infantry, vehicles and naval vessels, the Commander prepared to batten down the hatches and hold off the incoming Soviet armada just over the channel. Given a few minutes before it arrives, he constructed many defenses and ships to defend the Gladius systems at several points. He also reinforced his ground forces with fresh units in order to hold any incoming airborne and amphibious assaults. Allied Command advised him to reactivate several old Grand Cannons with Engineers to help reinforce the coastal defenses.

After a minute, Command gave him permission to use the ultimate Alliance aerial support unit, the Thor Gunship. He soon constructed more and placed them at several key points across the coast in order to defend against infantry and air attacks. Just before the Soviet armada showed up, several Battleships arrived to assist in the defense of the country.

As expected, the Soviet force soon appeared just on the horizon, alerting the Allies about the imminent attack, The fight was hard, brutal and bloody. Many naval vessels, vehicles and troops lost their lives in the defense of the United Kingdom due to the sheer amount of firepower being brought to bear by the communists. Kirov Airships tried to make a quick victory over the Allies by bombing the Gladius system. However, the Commander was able to construct many air defenses in order to stop the Kirov armada.

Next, the Dreadnoughts arrived to see if they could break through the Allied line and destroy the Gladius ABM. Despite several missiles making near misses, the ships were soon sunk by Allied naval vessels and the Gladius was repaired quickly so that it remained in working condition. The Allies could not afford to lose even one of these devices. Soviet reinforcements soon showed up in the form of Chinese and Latin Confederation units in order to support the Russian advance. Much like before, the Commander held off the attacks as best as he could.

Allied Command soon warned him about a Tactical Nuke Silo being built in the area. While the Gladius could destroy any incoming ICBMs, it was specifically designed to destroy them while they were still high in the atmosphere. Tactical nukes, on the other hand, could be launched from a much lower altitude, ignoring the Anti-Missile shield. With this warning in mind, he prepared to send a strike force to wipe out the Soviet base being built in Calais while protecting the devices with his fleet.

Destroying all Soviet forces in the region

Now that the attacks from the Soviets had died down, the Commander ordered up his reserve force to attack the enemy bases in Calais. The fight was hard, many naval, air and ground units were lost as a result of the Soviet's use of heavy defensive positions. Despite all the losses, he managed to push through their lines and destroy the Tactical Nuke Silo, saving the Gladius from a nuclear fate.

After dealing with the Soviet's nuclear capabilities, the Commander ordered his units to wipe out every single Russian, Latin and Chinese unit in the region. He knew that if even one of the Dreadnoughts or Kirovs got through his defense lines and destroyed even one of the Gladius devices, the Allies would be doomed to a world of communists. With this fear in mind, he pushed on through and systematically removed all Soviet presence from the French city of Calais. Suffering heavy losses, they were forced to retreat from the region. After a long and bloody fight, the Commander could finally rest, knowing he saved the Allied cause.


The unflinching zeal of our men has discouraged the Soviets from attacking our last vestige, for now at least. Although we have lost much to both Soviet machines and mind control, we still survive, we still prevail. We will always fight back.
—Battlefield report

The Battle of Britain is over. The Allies successfully managed to fight off their Soviet attackers and kept the Gladius system intact. The Euro-American forces' courage and determination managed to discourage the Soviets from trying to attack their last stronghold in Britain, at least for now.

Although the Allies, especially the United States, have lost much to the Soviet war machines and their insidious mind control, the Commander assured his lieutenants and his forces that they still survive and still prevail. Soon, the Allies will fight back to reclaim Europe and North America from the Soviets.

Though not explicitly known, it is possible that the Paradox Project was resumed in the safe confines of England under Siegfried's leadership with the assistance of KI scientists, and the result will hopefully gave the Allies an edge to turn the tide against the Soviets.

Two years after the Third World War ends, an unexplained deadly attack in Moscow brought chaos and disarray over Soviet territories, giving the Allies a chance to mount a rescue mission on Tanya in Poland.

  • The Russian enemy will eventually build a Tactical Nuke Silo. The top Gladius will always be the target of the nukes, which can take it down with one strike if not protected with a Force Shield prior to impact.

Easter egg

  • Located just east of the northern Tech Field Hospital is a damaged hut. If the player repairs the hut and then garrisons it with an infantry unit, 2 veterancy crates will spawn below the hut.

Behind the scenes

  • In version 3.0, the destruction of a Gladius structure caused a MIDAS to strike the player's base after a few seconds, destroying everything and ending the mission with a Game Over; while in version 3.3, losing a Gladius structure will end the mission immediately.
  • On Normal and Mental difficulty prior to version 3.3.5, Volkov and Chitzkoi would be paradropped at the east of player base. Actually, Volkov and Chitzkoi are destroying the Psychic Beacon in Xizang at this time, so it was unreasonable for them to appear here.


  1. Text at the start of mission: "It took the Soviets just 6 months to leave us in this state. The United States are in ruins and we were forced to withdraw whatever we had left to Great Britain. "
