I am a rebel player myself, but my daughter is a staunch Imperial player.
So whats in the box?
There are 6 different pilots in the set, 3 generic pilots and 3 named pilots.
The generic pilots are the cheapest and lowest pilot skill "Academy Pilot", then Obsidian squadron pilot, and finally Black squadron pilot. All cheap choices, and the only one with an ability is Black squadron pilot who can take a pilot skill. Each of those pilots come with 2 cards in the core set.
So all cheap and useful for filling out numbers, but nothing special, until you get to the named pilots, these guys are great value, with good but not game breaking abilities such as Dark Curse.
Next we have one of my daughters favourites, Night Beast.
The final pilot is Mauler Mithel... another of my daughters favourites.
Overall the Imperial pilots are solid, versatile and can rock in any of the missions, especially the named pilots.
