Prototypes
You may use the Design Workshop screen to create new unit types. Whenever you create a unit using a weapon, armor, or chassis type which you have never used before, you must prototype the unit.
A prototype unit requires an extra +50% Minerals to build, though it receives a bonus +1 morale upgrade in compensation since experimental weapons are often given to crack, well-trained troops.
Once you have prototyped a new unit, you may build that unit in the future at no additional cost.
Building a prototype also counts as a for equal or lower-valued components.
Chassis prototypes only count for the same types of chassis: air, sea, land.
Build completion is done sequentially, in the base sequence as shown on that unsorted display ‘F4’. Once you have completed your prototype, units constructed later in the queue, even if built in that same turn do not have to pay the prototype penalty.
