The goal is, well, to survive. Everyone spawns at the starting position, after the countdown, you can either try to get some weapons right at the beginning, or go and find yourself better equipment somewhere in the arena, there are lots of hideouts where you can find rare weapons. You can explore dungeons, buildings, ruins or even old temples / places. But beware of traps, those can be a quick death for you. You can even build teams together with your friends and form your own little „districts“. If you die, you are no longer in the games and need to wait for the next match.
