Cloaking

New tech available

the Cloaking enable the construction of Cloakship, Holoship and Cloak Generator (bases defense)

the Cloakship reduce the detectable size of the fleet, making it harder to be seen until its closer to the destination

The Holoship does the opposite, make it appear the fleet is bigger, with more ships

The Cloak Generator hides a base from the opponent Stellar Cartography, so it can not see your base if his Cartography level is smaller than yours Cloak level. If he click on your astro he can see it, but cant on the Scanners page.
