I have an idea for new weapons :
Particle Beam - weapon shooting a straight beam of ion particles that in the same time decharge the shields and weapons, could have very high damage + very expensive
New rockets
Antimatter warheads - very strong and very expensive weapon can destroy middle sized ship in one hit, but very unstable it can be very easilly shooted down with the point defence system
Nuclear warheads - nearly same as the previous one but with benefit of radiation damage
full hull shield - shield that will cover the whole ship it would prevent the backstab maneuvers that could sometime happen (and would maybe have cool animations )
