What's the story?
Errmm .. thanks !
It pretty much follows the storyline of the original FS2 campaign.
The subspace portal to Sol is reopened relatively soon. Sol's rejoining the GTVA gives a boost to technology development.
They start to build huge supercarriers with "field drives" that won't need to use the stable subspace channels, shielded and powerful, etc.
Seeing the chance to achieve tech superiority over the Shivans, they start a project (TCP) to rebuild and modernize the fleets and try to move first.
However, something unforeseen happens ... but that would spoil the story anyway.
The prelude is written in more detail on the story page:
The beginnig The player starts off as a young pilot on the GTD Aquitaine of the 3rd fleet, tasked with supporting the project and guarding key installations. But I really don't wanna spoil it for anyone.
