Brief Summary
Springfield is a large dried out dam area with three bridges, and a dry riverbed that splits the map in two. On one side of the map exists two command posts well fortified and shielded. One is ensconced within several layers of city metropolis, while the other seems reminiscent of a port-side loading bay for ships.
On the opposite side of the bank, three command posts exist. This side is where the heaviest struggle for CP's takes place, due to there being more CP's on one side than the other. One CP is stationed far in the corner of the map on an high-rise platform, upon which one can see the entire battlefield. One CP is stationed dead center of that side, and is protected by several buildings that curve inwards to shield the CP.
The last CP exists in a farm land area with small buildings and silos. It is in the Farm area and the Metropolis where most spawn patterns of the red and blue sides are located. Rarely will the game decide to spawn players in the Metropolis and the Port Bay area, opposite ends of the riverbank, or the Port Bay area and the Farm.
Topography of each area
Farm Area
Most often, one will find themselves spawn inside the Farm area, looking towards the Port Bay area. From here, the left most spawn point has the best chance of reaching the Farm CP. A bridge extends across the dry bank towards the Metropolis area, and a road passes between the bridge and the Farm. The right most spawn point inside the Farm Area has a clear line of sight to the Shielded Farm area and the High Rise.
A common tactic starting from here is to rush and seize the High Rise and the Shielded CP's, as this gives their team three CP's off the bat. The Farm area and the River Bank possible spawn areas are the three best spots for slow-moving artillery robots to deploy, as they can cover a large area with support bombardment and heavy fire.
Metropolis
Robots spawn across the back road, farthest away from the Port Bay and within 300 meters of the Metro CP. From here, the nearest spawn point is a toss up between the Farm area and the Port Bay, although the Farm CP is considerably easier to get to alive.
