Silica Basics
Near the green circles with the dripping rock inside, construct a Bio Cache. These are where you should gather your resources. Eventually, they run out. When it runs out, shrimp will search for a new one by moving from the closest Bio Cache to the closest dripping rock.If left alone, shrimps will automatically assemble and defend themselves (they also won’t merely ignore attackers who are in aggro range).
To gain access to additional resources more quickly, construct nodes in a chain that point in the direction of other resource points.
Build more spawning areas as your economy expands to produce units more quickly. More than one unit may be queuing.
Build a quantum cortex, then when you have the resources, enhance it. This will make new structures and units available.
There is no attack command that I can locate, and the AI is quite stupid. Make sure your units are close enough to them to aggro if there are adversaries around.
As technology advances, you can construct new colonies. This doesn’t seem to give you anything other than a second headquarters in case your original one blows up and a larger building area than a node.
