First off. Blue had the advantage. They are closer to cover.
The bases could be bigger and of different shape.
The grass is a good choice. But you can raise the buildings off the ground to prevent it from entering the buildings.
More cover, buildings, barrels, ground, walls, fences, trees, shrubs, clashed spaceships, mounds of junk, and the crate.
I like how you did the class room.
This is my idea :: faram
