Productivity and Airship Upgrades
No longer can a Marauder Captain get by on just his good looks and charm. He must invest in the right facilities for training, construction and research in order to be prepared to compete against other Marauders.
All production rooms (Training, Engineering, and Research) benefit from something called Productivity. Productivity is a representation of both efficiency and skill of a crew in accomplishing their tasks. Each room has its own Productivity rating.
The higher the Productivity of a room, the less time a unit or tech will take to be completed. Units become cheaper as productivity increases, but research does not.
All captains will have sufficient Productivity to be able to produce any available item. For those captains who wish to improve the speed of their production, they can get airship upgrades to increase their productivity.
The standard facilities on each Captain's airship provide a base productivity of 10 for training, engineering and research. If a captain wants better productivity, they will need to get airship upgrades.
Upgrades for the training room, engineering, and the research room are all available, as well as an upgrade for improved storage. See here for more information about this.
a) Total Room Productivity
b) Ship Upgrades
Remember that airship upgrades are permanent, so they benefit from some long term planning. You should weigh up the upgrade options carefully. May there be clear skies ahead!
