Palaca

The Palaca enables the building of Astro's which can be traded for Hero's once you have a Hero you can then build an Inavasion Ship, a Colony Ship or a Mothership (as long as you have completed the required reseach in the Space Academy)

Tou build the first Hero you will need 3 Astro's for the second you will need 4 Astro's for the third you will need 5.....and so on so they can be costly as each Astro costs 120,000 of each resource!

To build the Palaca you need the Headquarters at level 25, the Space Academy at level 25 and the Orbital Sipyard at level 10

Palaca's maximum level is 3
