As your Empire developed advanced technologies, they also began turning their eyes & ears to the stars.
Extraterrestrial life, it was believed may in fact be a common occurrence. So as your realm begins heading for the distant
corners of the galaxy, you also start scanning the stars for signs of intelligent life.
Much to your surprise, the first day the antenna array turned on it crackled to life.
You. Are. Not. Alone.

A quick scan of the galaxy and you have found a communication pod hurtling through space, blasting a fierce image as well as the following message:
We are the Galactic Order Assault Team. Resistance is futile.
We have been watching you throughout the ages, we are beyond compare.
For I am Billy. And these are my G.O.A.T's.
Our fleet already patrols the galaxy, any hostilities towards us will bring overwhelming, swift justice to the rebel area.
There is no hope. Give up hope now. We are only getting stronger.
Semi-Cooperative MissionAs described
here, any clan that reaches the 500 Power Point threshold that wishes to win the game must meet the "soon to be announced co-operative mission". This is that mission.
NO FACTION CAN WIN, even if the 500 Power Point Requirement is met, if the GOAT's faction is not vanquished.
Billy and the GOATs must be stopped at all costs. As the strongest of all the factions, you must work together to destroy them. Over time, the GOATs will only grow stronger.
Launch an early strike, or wait and develop your technologies, that is up to you. But as time goes on, Billy only gets stronger.
You can choose to assist the galaxy in this endeavor, or to avoid them. However, no faction can win if the group does not work together.
It will take more then one faction to take down Billy.
This is
not a "fully" cooperative game, where once the GOAT's are destroyed everybody wins.
This is a SEMI cooperative game, in that this task must be completed before any faction can claim the 500 point power victory.
You still are playing versus the other factions, but those factions must also band together for any hope to remove the overwhelming powerful force of Billy.
