A savage battle between you and your opponents is waiting for you ahead in CastleArena.io! Just prepare your strategy for this combat. In this IO game, you are supposed to use your budget wisely to purchase the buildings as well as send out your units. They will help you deal with the enemies by fighting them back and keeping your home base safe. The enemy will send his units out too, so make sure you time your assaults carefully. Don’t forget to upgrade your buildings and troops to power up them. If you do so, they can unleash stronger forces. Buildings can give you a better outcome than the units do. Also, you need to keep in mind that you won’t get money or wood from the unit cards. Be sure to use your earnings carefully. Your goal is to kill the rival and become the ultimate winner. Wish you luck!
