Cojaniz Square

Like the previous map, this one has two portals. Like before, the best way to deal with these is to block off the path leading to one of the exits. The enemy flight path will come in from the northwest as well. The first portal that will be active is the western one so you have to start placing your towers around it.

At Wave 12, the other portal will become active so make sure you have defenses around there as well. If you can divert the path to the northeast corner, that will be better. It will help also in the later waves to place a comm tower and a holding tower in the northwest corner where the airborne enemies will be coming in, along with some skywatch towers. This will help establishing your air defenses while earning some good cash for it.
