Because an idle constructor can be an easy enemy target, the commander and investor should be familiar with what asteroid is required for each building so that the constructor can quickly begin building.

Generic --The generic asteroid, code-named A, provides the foundation for your starting station, the link to Central Command. You can also build Outposts, Shipyards, Teleportation Receivers, and Refinery Platforms on these potato-shaped rocks.

Carbonaceous Rock --This bluish asteroid is the basic building block of the Supremacy Center. The Supremacy Center is perfect for quick territorial gains, as it provides the items you need for firm, decisive moves against the enemy.

Uranium --Code-named U, this asteroid is needed for building the Expansion Complex. The hot-looking rock will supply your Expansion Cneter with the energy it needs for offensive and defensive operations.

Silicon --This asteroid, code-named Si, is the foundation for the Tactical Laboratory. Once you have a Tactical Laboratory established, you'll find you now have the ability for deep-space enemy missions on their turf.
