AQ2 will have more ships, more weapons and more fittings. All the existing ships will be in AQ with more added.
AQ2 has a full mining and trading feature so ships like the Wyrm and Startrader will be pilotable.
The way ships are fitted has changed, there are now dedicated slots for shields, engines, armor and some new systems.
There are extra slots for Turrets and Internal fittings. Each turret can also have a modification applied as well as custom ammo.
