Falsly accused of mass murder, contract pilot Jake Logan (you) are exiled from the sol system to the fringe of civilized space where corrupt corporations (most notably The Galactic Spanning Corporation AKA Galspan) fight for corporate control. However, the colonists of the fringe have banded together into the Bora Mining Guild (the Bora) to fight off the spanner agenda.
You play as contract pilot Jake Logan who is very quickly thrust into this conflict and forced to choose one side or another.
This game is simply awesome. Not only are you able to customize your ship and its armaments, but the missions are adaptive so that what you do beyond the mission objectives in Mission A could dictate wether or not Mission B becomes available or is replaced by Mission C.
Each side (Bora and Galspan) have a fully playable campaign under their flags as well as quite a few independent third party missions (which for the most part are available regardless of which side you play)
Complimenting this are two distinct (but similar) endings to the game dependent on which side you choose.
Great plot, great flight simulator Well worth the money!
