Keep Fighting

In the year 2040 humanity was struggling to keep up with supply and demand and as a result many smaller countries collapsed while larger ones started to fall apart. To keep themselves alive the biggest nations came together designed and assembled new technology to keep humanity floating. While the new technology like nano machines able to construct whatever was needed and hydroponic farms that produced more food then what was ever produced before they were unable to create a new source of energy to sustain this. Desperate for something they decided to use Mercury to begin constructing a Dyson Sphere they started in 2044 but when the sphere was only 8% complete in the year 2045 an alien species attacked humanity. It wasn't without warning however a number of decoded messages from probes sent by them indicated humanity was ready to join the galactic council but would need to endure a trial. Humanity was not ready for it the first alien wave killed 40% of the population now down to 2 billion and a fraction of their most intelligent scientists they needed something else. Using the cores of the alien invaders known as the Metrix they created the Armorers using the cores of the aliens with the nano machines they were able to form weapons capable of fighting the Metrix. Only a few people were capable of linking with the alien cores but those who survived the initial attack were the best rated. In the remaining significant counties in the world the US, Russia, Britain, Japan, and France Battle Academes were constructed to teach Armorers. It has been six years since the attacks first started the Metrix mothership stayed in the orbit of Pluto all this time sending parodic attacks that were repelled most of the time with minor loses.
