What is this i have 2 shuttles that i like too use but don't get what doom shuttle is

Shuttle with Vader crew

What so good with him as crew

The omicron shuttle is cheap and has a good amount of hull and shields, so despite a shuttle not being particularly scary on its own, with Vader it suddenly becomes something you can't avoid because of the automatic damage it can cause.

Think of it almost like a kamikaze - point it at something that costs more points, start Force-choking fools with Vader, and as long as you kill something more expensive than the shuttle before it inevitably dies you've profited.
