As it can be understood from its name, Fightz io is a multiplayer fight game. In this game, there are your opponents as well as wild monsters and animals. So you will fight with all of them. While you kill the monsters, you will get crystals that increase your level and also upgrade your weapon. As there are lots of enemies around, you need to think and act fast. Attack the opponents that you can kill. But stay away from those that are stronger than you. Note that you need to start from the beginning when you are killed. So think twice before you attack something!
