The HQ is your largest building and your base of operations. Builders are produced at the HQ, and they bring resources here for processing (until a Resource Bank is constructed). Losing your HQ to an enemy means you’ve failed the mission... and left the mindless builders standing there with only scraps in their hands.

Building a Robot Factory allows you to produce basic soldiers and medics – mindless fodder, err... the heart of a successful battle. After a Workshop is built, the factory can be upgraded.

After building a Robot Factory, this can be constructed – allowing you to produce heroes.

After building a Robot Factory, the Workshop can be constructed – allowing you to upgrade 3 types of robots (soldiers, medics, heavy soldiers) up to 2 times each (Veteran and Elite levels).

Building a Resource Bank allows you to increase the production of scrap metal.

After upgrading a Robot Factory, a Radar can be constructed – allowing you to see enemy units on unexplored territory.

After building a Robot Factory, you can build Turrets. These rotating cannons are capable of inflicting massive damage to enemies.

After building a Workshop, you can start constructing the upgraded Heavy Turrets. These have a greater range and are very effective against enemy heroes.
