Herr Hitler's war machine is operational- power armoured soldiers striding across europe with battery packs whining as their crush resistance. Vast mechs clank across the plains scarred from the previous war, planes scream across the sky, the whirring crackle of electro-guns hammering down, the roar of stuka klaxons echoing through the air. To the east, Japan stands, screaming warriors backed by demons and monks, balls of chi pinballing soldiers around like toys.
Arrayed against them? The Allies.
Britain stands ready- masters of genetic modification and bioengineering showing it's form in long-dead creatures striding the Earth once more, arrayed in front of minotaur handlers- eagles the size of planes with machine guns mounted on their backs and zepplins made from great living leviathans, tigers the size of jeeps and with a hunger for metal.
France- After their humiliating defeat in 1914, stand ready to defeat Germany, electric anti-armour weapons crackling loudly, millions of men prepared to fight and die in protection of their Motherland... And we don't talk about Russia.
Hello! Welcome to the Weirdest World War, a 'historic' RP set in a universe where all of the powers are superscientific geniuses and every soldier is more than a little crazy. Think Wolfenstein: The New Order; but with everyone being the nazis with twists.
Very simply:
The Nazis are Stupid Jetpack Hitler with mech suits and power armour.
The Brits are bioengineering madmen with armies of wacky creatures
The Japanese are demon-summoning monster-controlling samurai again
The French are zerg-rushing anti-armour infantry with fanatical devotion
The Russians are... We don't talk about Russia.
