Void of Heroes is a first-person shooter multiplayer game based on a comic series available on Google Play books. Choose from a variety of Mechs and battle with players from across the globe in multiplayer PvP matches. You will also have the opportunity to play in the new battle royale mode, where you will fight for your life in a limited amount of time with a vertical rise-and-fall battlefield.

The comic series focuses on the story of a hero who is forced into the void, where he will find himself in a never-ending battle for survival. He will have to fight for his life and try to make it out of the void. This is where you will find your opponents and the Mechs that will fight for you. As you fight, you will earn your skill points, which you can use to improve your abilities. You can choose from three trees to mix and match your abilities, and the more points you earn, the more you can improve. 

You will be able to select different weapons to use in your battle. You will be able to use an Assault Rifle, a Machine Gun, a Shotgun, a Sniper Rifle, and a Laser Gun. You can also use a variety of other weapons, such as a grenade launcher, a melee weapon, and a baseball bat. You can also combine different weapons to create an even more powerful one.
