In Roter.io, the world has become a post-apocalyptic wasteland and people are trying to kill each other for their ultimate survival. You found yourself stuck in this world, and you are only armed with a tank which must be used wisely to go against the world. You need to take control of the tank around the map in an attempt to gather as much metal as possible then use them as ammo or to improve your tank. Besides the tank, you also own a small piece of land that is filled with fuel, and you must do whatever it takes to defend this kind of resource. When you come across any enemies, try your hardest to shoot them down before they have a chance to destroy you. Do not stray too far from your base, or else it will be attacked, causing your game to be over. You should play aggressively to wipe out all opponents standing in your way then get to the top rank on the leaderboard.
