Blue Guys: Nextbot Challenge is a survival game that combines the elements of a classic survival game with a fun multiplayer experience.

You are the only survivor after a mysterious asteroid hit the Earth, sending everyone to their doom. All of the other players are dead, and the only way to survive is to explore the planet and hunt down dead bodies.

You can pick from one of several characters to start with, but over time, the game will open up and you will be able to customize your character with a wide variety of different weapons, armor, etc.

You will also be able to pick up and use different items, such as a pickaxe, a bow, etc.

The game is completely free to play, so there is no need to worry about any kind of payment.
