Warcall.io is an action online game where you find yourself in an arena full of enemies. the main mode here is battle royale, so you only win if you stay alive last. in addition, try to take coins for which you can improve your character in the menu or buy a new one. it is also possible to upgrade your armor or weapons. but you will need diamonds for that, so try to get them as much as possible. the only downside to the game is that it doesn't include multiplayer, so you can't play with friends.
