In the early 21st century, war broke out across the world. A reason was never found, a reason never given. Country fought country, ally fought ally. In the first month alone there were over two billion deaths.
The rough sequence of events, pieced together over a painstaking two years of battle and non-communication, was that a nuclear strike on the shores of China by an unknown aggressor had lead to China launching tactical nuclear strikes against the US and Russia, one of whom it believed the original attacker.
The United States was first to respond, launching nukes in retaliation that decimated most of the rest of China. Russia followed up and finished off China for good, those that survived were soon killed off by radiation, and those that survived in secured bunkers had nothing left to fight with.
The US and Russia, both apalled that the other had launched nuclear weapons then turned on each other and destroyed millions of civilian locations in both countries, yet failed to strike against military targets.
After that it was everybody's war. Allies became involved, and eventually got entangled in their own conflicts. With each country's resources engaged in their own battles, allies could do little to help each other and treaties collapsed. With no ties to other countries, every country on the planet was now in a fight for survival, all versus all.
This is the tale of a world gone awry. It places you in the seat of today's greatest weapons. There will be a great many countries and vehicles to select from, each user taking a whole squadron, and groups of five users forming a country or organisation's army.
It seems every organisation on the planet has a battle to fight and the means to fight it, as terrorists, mobs, gangs and the world armies clash in their own scaled wars.
