Beat the game and make a clear save file. When this clear save file is loaded from the title screen, a number of features become available. The clear save file unlocks New Game+, difficulty settings, and the ability to select pilots to be deployed in missions. New Game+ allows you to start a new game with experience, skills, parts, and money from the previous playthrough. Difficulty settings multiplies enemy HP and damage by set amounts: x1 HP/x1 damage, x2 HP/x1.5 damage, x5 HP/x1.8 damage, x10 HP/x2 damage.
