|“|| Commander, you have honored my family with your victory at Oki island. But now it is time take the fight to the aggressors. We must make Moskvin and Oleg regret than they ever stood against the Rising Sun. Attack Vladivostok and erase trace of the Soviet presence.|
Once this is done, the Pacific will be ours and our control over these waters will be as it was before the War. Bring them to the knees, commander. Make them pay for their impudence!
Having pushed the Soviets out of Japan's home islands (without Allied assistance) Tatsu now believed the time had come for the Empire to rise again as a military power. The first step to retaking the Pacific was to seek vengeance against the Soviet Union by striking at Vladivostok- again.
|“|| Time to end the enemy threats. This is the base responsible for these attacks.|
Clear the nearby outpost and establish a foothold.
Clearing the Soviet outpost
|“|| What is this? You think you can defeat me with such a puny force? This will be easier than fight with my wife last night.|
Arrival of the Giga-Fortresses
|“|| ''Tatsu: I am granting you our newest most powerful weapon - the Gigafortress.|
Soviet soldier: Eeaah! That "thing" is bigger than a Kirov!
Allies have arrived
|“|| Just a smidge more sugar in the tea and would be… Ah, konnichiwa, commander! I am afraid than you once again broke the conditions of the post-war agreements! Now you and these Russians must be put down for this little Uprising.|
- Giles Price
Unfortunately, at the precise moment the Giga Fortresses started to unleash its "God's Breath" upon the Soviets; Giles Price arrived with a sizable Allied fleet, intending to put an end to the uprising and uphold the post-war agreements. Not wanting the new weapons in the Allied arsenal to compromise their positions, the Empire delayed their assault on the Soviets and engaged in another vicious naval battle with the Allied navy. The Giga Fortresses made mincemeat of the Allied forces and destroyed their base with relative ease. Giles and the survivors decided to retreat before being captured (presumably to warn the Allied commander fighting the rebels in Japan), leaving the Empire to continue its attacks on the Soviet bases.
Destruction of the Soviet bases: The Second Fall of Vladivostok
Despite heavy Soviet resistance, the Japanese prevailed, leaving Generals Oleg Vodnik and Nikolai Moskvin to blame each other for their defeat, and recapturing the Russian port-city of Vladivostok for the Empire.
|“|| You win today. But don't think for a second that these new lands are safe.|
- Oleg Vodnik
With the second fall of Vladivostok and the Allies now beginning to become aware of the Imperial Uprising, Tatsu now believed that the commander had regained the honour of the Empire of the Rising Sun and now prepares to expel the occupying Allies from Japan.
