In Auto Defense you'll find the typical 'tower defense' graphics. From a bird's-eye-view, you'll be able to clearly see the progression of the rival waves as you try to cover all the gaps they could possibly make it through to reach your territory. The game has a very simple gameplay, but you have to keep in mind that you can only use the circular bases that appear illuminated on the grass.
In Auto Defense, you can increase the number of available bases to house more and more cannons. This is important to be able to stop the most challenging enemies when the size of the rivals increases. In any case, you'll always have the option of combining some of the towers to get much more dynamic attacks that will be enhanced by the proximity of turrets that are compatible with each other.
As you unlock new cannons you'll have many more options to create strategies to surprise your rivals. By simply sliding each of the towers to the free positions, you'll deploy an arsenal of weapons that will make it difficult for your enemies to progress. Using these tactics you'll ensure that your castle is protected to continue exploring new territories that you can access in future levels.
