19: Toothy Marshes

You can place two of your heavy hitters in the middle south portion of the map where the enemies spawn. You can place a healthgun there to help them secure a pre-emptive strike position. There will be airborne ghosts that will come in from the west so place two AA batteries along their paths. You can place one in the westernmost side of the map where they spawn. Of course, you should also place Blamwitzers in some of the inner tower spots since they can help you deal with both aerial and ground targets from a long distance.

Be careful of some enemies since they can take a shortcut from their spawn point directly to the last corner leading to your HQ. Your HQ has a mounted gatling tower. You must change it to a Blamwitzer as well. Place at least two shock towers, one preferably near your strike position near their spawn point while the other should be along the middle of the path. The floating wraiths their area shields should be dealt with as soon as possible since they can slip through your defenses. The last wave will include slow moving but very resilient enemies, along with a large number of airborne enemies from the west. At this point, you should have already erected several fully upgraded towers. You’ll need to move and reposition your heroes, especially if some enemies got past your pre-emptive/ ambush point. The battle should be manageable as long as you have some heavy firepower in your disposal.
