|“||Having failed to clone the world leaders, Yuri plans to capture the real ones. Defend them at the Houses of Parliament in London, England...then deal with Yuri.
- Mission briefing
|“||This is a very important meeting commander. If this treaty ratifies, the Soviet forces will join us in the battle against Yuri.
With Yuri's main cloning facility in Sydney destroyed in Operation: Clones Down Under, Yuri's forces are now on the run. At the same time, the Allied Forces that were reinforced by the Time travellers had halted the brunt of the Soviet invasion and have pushed the Soviets back to their territories.
However, Yuri was now a greater threat to both superpowers, so US President Michael Dugan telephoned Soviet Premier Alexander Romanov to sign a treaty that will cease all combat operations between the Allies and the Soviets and fight Yuri as their common enemy. The treaty was scheduled to take place in London's Parliament House. However, Yuri managed to discover the location by brainwashing Lt. Eva Lee as she briefed the Allied Commander. General Carville was forced to send the Commander to defend Parliament House from Yuri's assaults.
The President had asked the famed Allied Commander that IFVs and GIs should be trained immediately before Yuri can attack Parliament. The UFOs should be located north of the building, while Yuri's base to the east is sending some Boomer attacks at their target. Alexander Romanov after signing that important bit will send his naval division to the east of that location. Two Amphibious Transports, Dreadnoughts and Sea Scorpions will arrive with Typhoon Attack Subs to destroy Yuri's naval forces in a game of war in the river.
Yuri had his own base located to the east of Parliament House. Despite the weather of thunderstorms across London, he of course didn't care about it and sent Boomers and a new card to play - the Floating Disc. This type of UFO can shoot laser beams at Allied or Soviet land forces by the time, anyone would have saw them.
Defense of Parliament House
The Allied Commander immediately prepared to reinforce defenses around Parliament House as President Dugan and Premier Romanov arrived at the site. The Allied Commander had a short time to capture any tech buildings in the city across the River Thames, before Yuri's forces arrived. To protect GIs from mind control, the Commander orders them to garrison buildings in London and shoot every Yuri infantry or tank they see. Ten GIs garrison the Big Ben as the last defense. The Commander also builds several defense facilities including Defense Wall around the Parliament House. Once Yuri arrived, he immediately sent waves of forces against the Allied defenders, attacking with fierce determination to kill the Allied and Soviet leaders by destroying the major site as a cave-in.
|“||And I think the Brute was bad! Yuri calls this thing a Mastermind. It's basically a big brain on wheels that mind controls everything that gets near it. Don't get near it.
- Lt. Eva, warning the Commander about Yuri's new weapons.
But the Masterminds can not control GIs in the building and they are also destroyed under the fire of the GIs. Yuri also sends Amphibious Transports through the River Thames, but most of them are destroyed by the GIs garrisoning buildings near the river. Only one transport lands and unloads a few Initiates and one Gattling Tank. They are taken out by GIs in the Big Ben.
|“||Holy cow! Commander, we got some kind of UFO on the scope! Either it's an alien invasion or Yuri's been watching too much TV!
- Carville, seeing the first sight of a Floating Disc.
While the Commander repelling all of Yuri's ground forces, Yuri had a new card to play - the Floating Disc, which began to bombard enemy ground forces with devastating laser beams by the time that the taskforce noticed - most of all was Carville. They are able to drain power from Patroit missile system and render the missile useless. But the Commander builds one Aegis Cruiser and it takes out the Floating Discs very quickly.
Destroy Yuri's London Base
After the last wave of Yuri attack force is repelled, Carville informs the Commander that the treaty is signed and the Soviets send a fleet to reinforce the Commander. Suddenly, several Yuri Boomers rise to the surface and assult the Parliament with missiles. The missiles are shot down by the Aegis Cruiser and Soviet Sea Scorpions. Then Soviet Typhoon Submarines and Dreadnoughts sink the Boomers into the water.
While defending the Parliament, the Commander also builds one armer battalion including Battle Fortresses, Prism Tanks and IFVs. Two Soviet Rhino Tanks also join the battalion. The Commander transports the battalion into the backside of Yuri's base. The Battle Fortresses (with Navy SEALs and Soviet Tesla Troopers in it) quickly take out Yuri's tanks and infantrys. The Prism Tanks destroy the Oil Derricks in Yuri's base and cause a huge explosion, destroying several Yuri buildings along with many Initiates. The battalion is able to damage Yuri's Bio Reactors and power down Yuri's defense buildings, and then destroyed the entire base.
Then the Commander clears all remaining ground units of Yuri, and declares that all Yuri forces in London has been eliminated.
Yuri's failure to kill the Allied and Soviet leaders in one stroke left his army now definitely on the run. The Allies now worked with the Soviets and combined their intelligence from both Zofia and Eva Lee, who recovered from Lord Yuri's Mind control to pinpoint Yuri's main base of operations - Antarctica.
If the par time is beaten, the Commander is congratulated protecting the leaders well and repelling Yuri out of London. If not, the Commander is blamed that the leaders are scared by Yuri and the signing of the treaty is delayed.
- The parliament cannot be selected.
- If the leaders are forced to evacuate the parliament due to damage, the building will explode and they will automatically catch fire and die.
- The leaders will remain in the parliament for the rest of the mission after the treaty has been signed, forcing the commander to keep defending it.
- The G.Is and secret service agents inside the parliament will not fire at Yuri's forces.
- In the mission briefing Lt. Eva is brainwashed by Yuri. However in game she warns the player about Yuri's Brutes and Masterminds. It could be possible she returns to duty after medical treatment.
