AOD: Art of Defense's post-apocalyptic world players can view is completely destroyed by nuclear war. Additionally, sales of the game have been completely destroyed due to tragic events that continue after the end of the war. Players will fight against bloodthirsty predators who are searching for information about a hidden project. At the same time, this group performs many evil deeds in order to accomplish their goals. Players must defend a single path to the base from approaching forces. The base stands apart from other war-ravaged facilities, with only one route accessible by vehicles and foot soldiers. Players can deploy towers in specific areas, as strategic spots away from enemy approaches.

After installing AOD – Art Of Defense, you can access a tutorial mode. This will give you an understanding of the game's mechanics in just a few minutes. Select a location and options for towers will automatically appear before you. Based on your current resources, you can choose a defensive strategy. Also look into the game's buildings to find helpful information related to defense. When you touch a building, you receive information about its defenses and speed. You also learn how fast the tower can target and damage enemies. Additionally, you know how many enemies appear in a mob and how quickly they move through an area. Because of this, you can place a tower with spaces to accommodate it— and many other features in the same space — making it easy to use. Defending towers require a different approach than attacking ones. Each building provides a different defensive strategy. Over time, more and more slots become available in the tower defense game due to the varying levels of enemy resistance. Waves of enemies will appear in different orders that players must memorize at the start of each level.

In tower defense games like Art Of Defense, players have the ability to upgrade buildings in order to best complete each level. They can choose to upgrade any structure; just be careful with the size of the upgrade you choose. Different enemy waves will increase players' money and tower strength— they need to be aware of this when making choices. The game's upgrade system for towers has a notable point that needs to be addressed. Players can view the ever-changing potential of each tower by observing how long it takes them to grow. Additionally, players can access lists of every tower included in the game. Each tower has its own skill tree, which gives them increased functionality. Players face off against blood-thirsty opponents in battle. Players enter a destroyed world where they combat evil conspirators who are searching for a lost project. You're able to place towers at specific locations on the route toward the protected target. Tying into each other, the short descriptions of each tower display its unique features. In addition, neighboring towers support each other. Players can use the cash they earn to purchase new buildings or upgrades. Doing this increases the strength and sustainability of their defenses. Upgrading the system grants players access to different towers with new skills. ———
