Invader shuttle

Invader attack craft. Still limited by the same limitations as mankind when it comes to space travel. They still need to slingshot around planets and they aren't super maneuverable. Weapon wise they have a charging plasma cannon that can wipe out a city block in one shot. Needs 1 minute to charge. In an atmosphere they are not very agile and most fighter planes can gun them down easily. Not much else is known about them.
