There were Valentines Day videos of the females from the game. Takara's is funny and gives an ideas of what to expect, then we get one from one of the actors in the game, RicFlair.
Speaking of Flair, marketing for Uprising included videos, videos that consisted of wrestling style promos where he would be attacked by someone in a bear suit, complete with Russian hat and evil glowing red eyes.
Doubles as a pragmatic move as well, since the building has some cash crates, and the level's money reserves are very low.
When President Ackerman betrays you in the Allied campaign, you are tasked with destroying a firebase at Mount Rushmore in order to preserve peace with the Soviets. The firebase is heavily defended, but its real teeth have to be seen to be believed; the defenders have weaponised the presidential busts. George Washington gets Eye Beams!
In the Soviet campaign, the Russians launch an attack on the Allied headquarters in Geneva. Apparently the most logical plan is to teleport in a fleet.
The entire cinematic where the Emperor's son warns him about an impending treaty-breaking surprise attack on...Pearl Harbor. The Emperor immediately says the islands are filled with historical monuments and half the Japanese fleet is stationed there, there's no way the Allies would be dumb enough to try that. The scene's played completely seriously (since WWII never happened in this timeline) but the player will likely be laughing aloud.
Unless you are scratching your head wondering how the Empire got Pearl Harbor without a World War II, considering the points of divergence are all after the Great War and even more after the USA's annexation of Hawaii.
Checking one of the terminals on the final level of the Yuriko mini-campaign in Uprising yields this gem:
Yuriko Omega: This is a laundry list. Literally. What do they need with 2000 plaid skirts?
A Self-Imposed Challenge involves killing the Emperor the final time in the Soviet campaign with the same Conscript as before. Obviously this would require the use of Natasha/Tesla Trooper dampeners and a lot of firepower to get even close to finishing him off, but still.
When President Ackerman is revealed to be a robot expy in the Japanese campaign, his controls are destroyed in anger when they learn that there is no "divine order", causing Ackerman to spaz out, full with smoke pouring out of his ears. J.K. Simmons losing his shit is a sight to behold.
The Soviets get two faction powers that have a somewhat hilarious correlation. The Magnetic Satellite power uses a giant space magnet to suck vehicles into space. The Orbital Drop power takes random space debris and throws it at the targeted area. Said space debris includes satellites, bits of rock and the vehicles you suck up with the Magnetic Satellite. Nothing quite beats levelling an enemy tank column by throwing their previous tank column at it from space.
Soviet Hammer tank has an ability to leech weapons from destroyed enemy vehicles. This doesn't seem funny at first, until you manage to leech weapon from King Oni - precisely, this will place a mecha's Eye Beam shooting head on the left side of tank's turret. It gets more ridiculous when you leech weapon from Allied Carrier, which gives your tanks One-Hit-Point Wonder attack drone.
