The ad for Slave I states:
The Slave I Expansion Pack allows players to take advantage of the Firespray’s versatile armament and heavy armor plating, as well as a host of lethal new upgrades. Imperial players can choose to arm this starfighter with a range of missiles, ion cannons, heavy laser cannons, and bombs. Slave I comes with a detailed miniature, four pilot cards, thirteen upgrades, and all requisite tokens. New rules and a new mission further expand your games of X-Wing!
Bombs seem a strange weapon to take to a dogfight, but it raises my hope for my favourite Imperial starfighter - the TIE Bomber! - to be in Wave 3.
Any theories on how bombs will work? Slave 1 did lay seismic charges for Obi-wan Kenobi above Geonosis and they did seem pretty effective.
