■WORLD
The story of a decades-long struggle to save mankind from destruction...
The BETA:
Beings of Extra-Terrestrial Origin and Adversaries of the Human Race. Unknown life forms first discovered on Mars in 1958. First contact with them was made on the moon in 1967, and by 2001, their unstoppable invasion of Earth had pushed humanity to the brink of extinction.
The world's nations attempted to fight back, each developing their own tactical surface fighters according to their own unique combat doctrine. But the BETA advance drove mankind from the Eurasian continent, and while the invasion is contained, for now, our attempts at containment are reaching their limits.
Can humanity escape from total and utter destruction?
The Tactical Surface Fighters (TSFs):
Humanoid weapons first used against the BETA in 1974.
Scientific advance has given mankind new ways to fight the BETA, and new TSFs are constantly being developed. As of 2001, the newest TSFs are the 3rd Generation Models.
