Gun Master 2: Build Your Own Guns is a free-to-play action game in which you can build and customize a wide variety of guns and rifles. You can do everything from changing the gun’s color to modifying its components. The more you improve your weapon, the more it will look like the real thing.

The game is set in a post-apocalyptic world in which you must survive. In this world, there are many hostile creatures, and it is necessary to equip your weapon with the best ammunition and accessories to be able to defeat them.

You will also need to shoot off the limbs of a practice target in order to earn points. These points can be used to buy new ammunition, accessories, and even new weapons!

If you feel like a real shooter, you can compete against other players and earn points by shooting targets. There is also a multiplayer mode in which you can play against other players.
