It comes with a learn to play, and a very nice rules reference.
The 3 missions are:
Ambush - Destroy all enemy ships
Raid - Destroy all ships or Destroy/Protect satelites
Rescue - Protect/Destroy Special Ship
Details, pls? These more than just themed dogfights - something along the lines of most of the 'large' ship expansions? Or, heck, the first core set (those missions were actually really solid)?
