The Story of Nexus is kinda bad mostly due to it's pace and narrative, a better way to resume it would be: An AI evolves beyond it's shackles (Common Cliche in Sci-Fi) and destroys it's creators (who seem to be alive now?), Angel, your AI, was designed to study and absorb "Mechanoid" technology to reverse engineer a way to destroy it, meanwhile it continued to spread across the Milky Way increasing it's computing capacity by assimilating networks like Internet 3, in the end it's assimilated by Angel and we get a funky undoing of earth's computerization.
Now the background story of 2 is that the Sol-Noah wormhole closed and Cromwell is trying to find a fay to fabricate them or cross the voids between solar systems... while earth goes back to being lead by corporate assholes.
That said, with the AI gone, I hope we get some more thought to go into the story.
