The entire Annihilation book craps all over the in-game lore. It's obvious that BW has no intention of continuing the story in this game and will simply just let it rot.
I mean, the main "villain" is a random nobody. Gravus is turned into a moron. Theron has a magical stick that can slice through any and all Imperial security measures without any trouble.
It's almost as bad as the JK waltzing though KAAS CITY alone.
Why they even bother having 2 sides in this game is beyond me. Just make everyone a damn pub already and be done with it.
The Gravus in game was very calm and intelligent.
