New user campaign by Blaise Russel called Sol - A History.
Info:
It is 2335. For 14 years, the Terran-Vasudan War had been slowly grinding
its way along, when the appearance of a third species changed everything.
An implacable foe that simply would not die, the Shivans resisted everything
the united Terrans and Vasudans threw at them. Their flagship, the Lucifer,
destroyed the homeworld of the Vasudan people, and now it's on its way to
Earth...
Over the course of four campaigns spanning 37 years, 41 missions and the
fall and rise of two inter-planetary powers, YOU are a soldier for Earth, a
warrior for the Alliance, thrown into life-threatening situation after
life-threatening situation... what part will you play in the developing
history of Sol?
