Battle Cats is a tower defence game by Ponos in which the player defends their tower against an oncoming horde of enemies using a variety of battle cat units. The aim of each level is to destroy the enemy's tower whilst defending your own. This is achieved through careful selection of the units that you build, how you upgrade your units and tower, and how you use special abilities.
Battle cat units come in many different forms each with their own unique uses. For example tank cat is useful for soaking up damage and bird cat is useful for hitting multiple enemies.
