The powerful Mothership is the one used the most by Time World players. Unlocked at a Shipyard level 16, they pack quite a punch.
They cost 5000 Ore and Credits to be built, and an additional 2500 Energy (which is 5 times more than the Battleship!). But it repays with a whopping, tank-like 1.250.000 HP! It's Attack is 32.000 and Speed is 100.
Each Mothership requires 8 command points. In other words you can have command/8 Motherships, rounded down.
