The PsiCorps surrounded the UK and deployed a large number of Gehenna Platforms in the Isles of Scilly to shoot down the Paradox Engine. Subsequently, the Paradox Engine and the Allied main force quickly withdrew.

But just as soon as it was about to succeed, the Allied secret weapon, the result of the Paradox Project, the Paradox Engine, was lifted off, and its time freeze ability destroyed the Epsilon attack force ( Epsilon 17: Godsend). At the same time, with the first generation of chronosphere and as the Allied forces marched to Morocco, the Aerial Fortress Irkalla was transferred to London to give the Allies a critical strike.

The Amplifier and the Beacon were just a bait to lure the commander away from the UK ( Allied 16: Ghost Hunt). However, they only to find that the local Americans was not mind-controlled, but voluntarily joined Scorpion Cell. Through the liberation of Cannes ( Allied Special Op: Obstinate), the Allied forces in Morocco discovered a Psychic Amplifier that was under the control of the Scorpion Cell, and destroyed it. However, during this period, Epsilon recovered the first prototype of the Chronosphere from Germany ( Epsilon 16: Divergence). The Allies launched a counterattack on the Norwegian research facilities, preventing the Epsilon troops from stealing the Barracuda's technology and allows them to regain it. Eventually Morales successfully evacuated and the Epsilon cloning facility was destroyed ( Soviet 15: Exist to Exit). Yuri plans to assassinate some people who were blocking his plans, including Morales, who sent a distress signal in Rio de Janeiro, and the arrival of the Latin Confederation’s troops confirmed that the Epsilon had made a number of Cloning Vats in the city. In order to stop the effect of the European Psychic Beacons from expanding into the United Kingdom, Tanya and the European Alliance forces launched a raid on the Rome Psychic Amplifier ( Allied 14: Puppet Master). Yuri built a Psychic Amplifier in Rome to draw the Allied forces out from the London Fortress ( Epsilon Co-Op 06: The Cardinal). Epsilon also protected the Mastermind research and development facility in Romania from the Soviet counterattack ( Epsilon 15: Memory Dealer). The Cloning Vats in Zaragoza, Spain, was infused with a "Terranova" genetic virus, creating Rahn and a large number of Brutes to destroy everything in their way ( Epsilon 14: Huehuecoyotl). The Epsilon forces also began to operate in Europe.

On September 5, in order to rescue Tanya, who was detained in Warsaw, Poland, Siegfried personally used the first chrono backpack ( Allied 13: The Mermaid). Taking advantage of the chaos within the Soviet command, the Allies also began to act. He not only raided Stalington, but also launched an attack on the Soviet Union's capital, Moscow, on the same day, stealing the Russian Topol-M platforms and killing Premier Romanov ( Epsilon 13: The Conqueror), while the Scorpion Cell actively cooperated with the actions of the PsiCorps and struck the Latin Confederation and the American invaders in North Africa ( Epsilon Special Op: Fallen Ashes). Fortunately, two Soviet colonels, Reznov and Krukov, who were stationed in Stalington, acted in time, and the General was rescued before fleeing to safety ( Soviet 14: Awake and Alive). The Soviet General successfully resisted the invasion ( Soviet 13: The Raven), but the situation changed: Stalington was quickly captured by an unknown army, and the General himself went missing. On September 1, 1984, the US rebels launched a large-scale counterattack against Stalington (formerly known as Washington D.C.). During this period, the friction between the Allies and the Soviets occurred ( Allied Co-Op 10 & 11: Balance of Power, Panzer Ace Soviet Co-Op 09 & 10: Combustion, Money Source), and Yuri also successfully prevented a Chinese agent from revealing the truth about Russia's MIDAS, allowing Russia to remain "strong" ( Epsilon Special Op: Taciturn). After the Soviet Union failed to attack Britain, the war fell into a stalemate.
