Artillery: It is a slow and lightly armored vehicle, but has a highly damaging weapon with fantastic range. It is ideal for engaging buildings and units at a safe distance.

You start at minimum with a CPU to construct buildings and scouts. Your main objective is to eliminate all enemy structures. Your secondary objective is to capture and maintain control of resource nodes. Scout the map for resource nodes and use your Scout to capture them. Build a Northbridge/Southbridge to create new units to protect your investments. Your choice of unit types will determine how you expand and how you battle opponent.
