I've added serveral new labels on this map pack due to the spaceship nature of it: Gun Turret, Generator, Engine, Radiator, Fuel Slot, Hangar. Those are not ment to do anything in particular in terms of functionality, but I think those can be good labels if you want to make a custom scenario and some mission objectives, like for example getting points for destroying ship systems while fighting on it's hull. Or if you are planning a campaign, where it will matter which systems of the ship has been damaged in a space raid before it lands on the planet or a space station.
My proposition here however, would be to consider including gun turrets as actual spots where a stationary turret of your choice is placed, helping you to defend the ship, as long as enemy do not destroy or disable it (by for example destroying certain number of generators on ship's hull). I think it could also be cool to use Hangar slots as the place where after set time, some more defenders spawn.
Destroying enough radiators, would probably cook the crew inside, or at least force them to avoid using heat generating systems of the ship.
Have fun!
