Phantom League: Pilot Academy, the second expansion for Phantom League, includes two separate and major optional additions:
- Battle rules, which change the battle system radically, and
- Galactic Balance, which make missions have a larger effect than just Recognition, and Surface Missions, which is another way to gather Recognition (and affect Galactic Balance)
Phantom League: Pilot Academy is meant to make a player's immersion in the world of Phantom League even deeper, while offering more tactical choices during battles. Phantom League: Pilot Academy can be used without Mostly Harmless, the first expansion for PL, although it includes a separate rules booklet for those who do use Mostly Harmless.
