Rules of Survival is a free mobile battle royale style game where 120 players drop from the sky and batte in an ever decreasing circle until only one person remains. The game itself can be broken down into three stages, the Beginning, you drop out of the sky unarmed and land in a certain area and gather your resources. The Mid-Game, you relocate to stay in the decreasing circle and try to stay alive, and finally the End-Game where you inevitably encounter enemies and seek to gain the upper hand to win the confrontation.
The game is available free on iOS and Android
