Version v1.16b32 currently has functional, purchasable one time use missiles which can be added to any player battlecruiser.
There are currently four types of missiles available: Anti missile, Large EMP, Longbow, and Anti Plasma. These can be built in Assembly and assigned to each battlecruiser in the Battlecruiser Lab.
Each battlecruiser has a missile capacity so larger battlecruisers can carry more missiles.
Along with this addition comes a change in the UI layout for battlecruiser icons spread out to make space to separate the weapon and power states from missile ammunition.
