You are in control of your armies that are the red spots on the maps, you control the direction in which each team moves. The Zombies are moving towards your line of control you got to stop them from crossing it.
The dark spots in the maps are swamps, confronting zombies in the swamps provide them with an advantage, they get to you faster while your troops slow down.
Autumn War Tips:
Try to engage the zombies before they are too close, this gives you an advantage of some space before they begin to take down your soldiers. While moving forward your soldiers will not kill as many zombies as they will when they are holding their ground.
If you begin to get uncomfortable with the number of zombies approaching fall back before they get too close. This will help slow down the pace at which the zombies are approaching. You can use charge when you see around three zombies left, your soldiers will take them down, if all three zombies are not going in for one soldier.
