Ace Combat Zero: The Belkan War review

Another introductory feature in The Belkan War is the Ace Style Gauge. As you play each mission, you're constantly graded on how you fight. You can go all mercenary, literally killing anything that moves, or take the noble approach and allow damaged enemies to escape with their lives. There's also a middle ground, where you kinda split the balance, but choosing one extreme or the other is the way to go - your actions will affect in-flight dialogue and mission updates, plus the game's ending.
