IN TD Worlds the user must organize the defense of the area from enemy attacks. There are three different worlds that require protection. Multicolored triangles attack the defensive redoubts. The player's task is to fight back with the help of a shooting tower. It is desirable to keep the green pyramid intact, which provides energy for defense. It is necessary to place the towers in the correct order. It is important to use pre-thought-out and developed tactics. In this case, the enemy attacks in waves, constantly increasing combat units. Aggressors come in several types, with their own weak points. This adds complexity to suppressing the attack.

In case of defeat in TD Worlds, you will have to start the level from the very beginning. In this case, achievements and weapon upgrades are lost. It is possible to qualitatively approach the issue of modification of the plasma gun. In the updated stage, enemies attack in a new order, have a distinctive arrangement and a different number. The influx of attackers is generated randomly. After the victory, the player is awarded bonus points. They come in local currency and are spent on acquiring new abilities for their structure. The only nuance is the ability to buy new weapons, which opens after passing certain rounds. There are additional stages that are not related to the plot. Special prizes are offered for their completion.
