Take one psychotic half-alien cyborg with an obsessive vendetta against the alien race humanity is at war with. Put him in a spaceship on the front lines. Add a commanding officer who doesn't trust him, a best friend who's desperately trying to keep him alive and out of the brig, a general who needs him under control, and hidden assassins who want him dead. Stir lightly and bring to a simmer. Then stand back, because this is a recipe for disaster.
