Category: Tower Defense
“Tower Defense” (TD) is a subgenre of strategy games in which the goal is to defend your territories (or possessions) from an aggressor. This is achieved usually by placing defensive structures along your opponents attack paths.
You should build a variety of defensive structures that would defeat the enemy in “kill zones” by blocking, impeding, utterly destroying their units.
