How to Play Celestia Duo - 2 Player Co-operative Board Game

About Celestia Duo, from BoardGameGeek:

Pirates are plundering Celestia's flying cities and escaping. Embark on a perilous chase in your aircraft to catch them before it's too late! Coordinate efficiently to foil numerous ambushes... but without being able to tell each other everything. Includes 2 3D aircraft to assemble! The Celestia universe expands in this cooperative game for 2 players with limited communication, mixing chase, risk-taking and strategy. During your journey, cleverly share cards to foil ambushes. Anticipate your partner's hand, because if one of you, on his turn, can't fight a die, the aircraft will take damage. Stop off at the right time in the flying cities to refuel and recruit passengers with useful skills... At the risk of letting the pirate leader get away! -description from the publisher
