You might not think that having a super-slow, yet maneuverable ship would be all that great to have in your squadron. But the Quadjumper brings more to the party than just being able to fit itself just about anywhere you need it. It has a toolbox full of helpful items it brings along. For example, there's the tractor beam for pushing and pulling your opponent's ships around. There's the scavenger crane that can grab bits of enemy ships and integrate them onto your ship. You can also outfit the Quadjumper to carry bombs. And with one pilot, you can even fling those bombs out the front of your ship (and then back up away from it). Precision bomb placement has never been so accurate before.
