Well, I'd hardly call a game in which you throw fireballs and drill through mutants in diving suits realistic, but you do have a point. I chose to match the pro-con assortments like so to make each upgrade fit into an easily recognizable fighter type: the first upgrade turns you into a slow-firing damage-dealer, forcing you to make each shot count but increasing your threat; the second allows you to survive better in prolonged firefights, at the cost of being dead by the time you empty your clip and the final upgrade turns you into a part-time Sniper.
