Battle cats is a tower defence game where you take over the world with "cats". At the start you fight other animals like doges, snakes, and elephants
But the more you progress the enemys start to get a little bit more odd. I dont think these are animals.
all enemys have a trait and most units have a ability to counter a traited enemy. The traits go from simple stuff like red, floating, alien. To stuff like a relic and aku (i think aku means evil in japanese)
The more you progress you will unlock upgrades and even more deranged cats to use in battle. There is currently over 700 units in the game. Some looking "normal"(in battle cats normal is still quite weird) to having units that just stick the face of a cat somewhere and call it a day.
Also with over 4000 stages to be beaten, safe to say it takes ages to beat the game.
Thats kinda if for the info. theirs no multiplayer (unless if you could the nintendo one)
As for the story, you take over the world, the future, and the goddamm Multiverse. While your doing this you resue some people then acidently go back in time. When your done there you are stuck in multiple universes with special destanations crumbling apart because of your exsistance. Remember when this was about cats vs animals?
