Revision 4

The Caisson is the transport ship used by Zero Company in STAR WARS Zero Company. It carries the squad from their home base, the Den, out to the missions scattered across the galaxy map, and it is flown by the droid pilot M-3VO.

The Company's Ride

Where the Den is a defunct bulk freighter berthed on the Ring of Kafrene, the Caisson is how the company actually reaches the fight. Every Tactical Mission and Operation the squad takes on begins with a trip aboard the ship, making it the link between base management and the battlefield. Because the company has no formal backing, the Caisson is the kind of working vessel a band of mercenaries relies on rather than a polished military transport.

M-3VO

The Caisson is piloted by M-3VO, a droid who serves the company between missions. The pairing of a workaday transport and its droid pilot fits the game's grounded, lived-in take on the Clone Wars era.

In Star Wars Lore

The Caisson is specific to this game. Anything the game does not show on screen is not confirmed as part of Zero Company's own telling.
