Missiles are the secondary weapons available on all type of ships. There are two types of missiles, homing and unguided. Homing missiles require the player to lock onto the target in order to fire (They can also be fired without locking-on and then follow the same rules as unguided) and can be avoided by using flares or dodging/weaving in and out of objects. Homing missiles are useful for longer ranges when Guns can't reach. Unguided require no lock-on and aren't affected by flares but are easily dodged at long range, but are useful for close-quarters.
Missiles are loaded in Cartridges. When you expend all of the missiles in your cartridge, it will begin reloading, which is a lengthy process.
Missiles are separated by ship class, with interceptors only able to mount small missiles, fighters medium and frigates large. In addition, there are special missile types that can only be used by certain roles.
