We are after the story line of Zero Hour, and the world have changed, and you think Earth could never be shaken more as was in the 3rd World War, you were wrong...
It is a beast lol.
Currently the mother ship starts with 6 Deffence drones, this can be upgraded 6x times, each times 6 drones ( will present the bulk of it's fire power also act as an meat shield ) they respawn just like the angry mob members, with the exception, once upgraded, it will stay such way.
Also experimenting with the main beam weapon for the mothership, that needs some extra work for sure.
External hull upgrade works properly, you can destroy it, with it expose the core ship to higher ammunt of damage.
The models still under editing, currently adding special production and laser bones to it.
Next time you'll see the harvester ship which will responsible for income, also an special upgrade that allows the MS to produce cash ( hacking ) if doing that, no unite production and similiar activities.
thats all in nutshell for now folks =)
