Colonisation: Aftershocks

Humanity is still locked in a battle for supremacy with the conquering alien
invaders, the Race. The German Reich has finally been subdued and the
Race believe it only to be a matter of time before the rest of the planet follows
suit.

However, they underestimate humanity's desire for freedom and the lengths
they will go to gain it. With America and Russia holding the alien invaders
off in a technological standoff, the disorganised red armies of Mao Tse-tung's
revolutionaries causing havoc and the ever-increasing dependence of the
Race on the addictive substance ginger, the Empire realises that the colonisation
of Earth may only be achieved through its total destruction.
