The free survival game survivor iofeatures zombies and other adversaries attacking you as you try to stay alive. In order to stay alive, you need to gain experience and level up so that you can acquire self-defense skills. In order to obtain the evolved version of a talent, which is the best version of that skill that it is possible to be, you can level up your skills five times and then again. For instance, the guardian skill can develop into the wheel of death.

The game also features bosses, and whenever you fight them, you are rewarded with a magnet that collects all of your experience points, meat that heals you, and a chest that allows you to level up one of your skills. There are also mini bosses, which are simply modified copies of regular opponents that are larger and more powerful.

Participating in one of the game's 85 chapters or trials is the primary objective of this game. (So that the chapters consist of additional tasks.)
