This is a turn-based strategy game with a twist on the traditional gameplay. The twist is, instead of directly controlling the characters IN THE BATTLE, you will be designing the strategies BEFORE THE BATTLE. When the battle begins, your units will follow exactly the strategy you defined, and all you can do then is just watching.
Different challenges are presented in different levels. One strategy won't be able to defeat them all. You'll need to learn, adapt then conquer.
