In Gun Builder, you can create your own custom guns. Have you ever wondered how the most deadly guns are built and what kind of components they include? Wonder no more! From famous weapons like Uzis to tiny pistols, you can create any type of gun you like in this entertaining game. You can switch between two game modes in Gun Builder. You can create a totally customized gun of your own, or follow a blueprint to successfully assemble a particular type of weapon. What kind of guns will you create?

If you are of the opinion that the best defense is a good offense, guns are just the weapon for you. Get ready to explore the process of gun making in this addictive game. Gun Builder offers 2 different game modes that you can enjoy. The first one is Assembly Mode, where you have to build a gun according to the blueprints you can collect in each level. On the left side of the screen, you can see the parts section with different categories listed. These are the grip, frame, barrel, and any add-ons for that extra special touch. To build a gun, drag a component from one of the categories into the building area, and place each part on the right area of the blueprint. When you’ve completed your gun, it’s time to test it. As the gun’s creator, you get to be the first person to conduct the tests. Do some target practice to find out whether your creation works. When you are satisfied with the results, you can move on to the next level. In Assembly Mode, you can unlock new parts for each level you pass. Each level will become more challenging, unlocking new gun designs that require more parts. The second game mode is Creative Mode. You can use the parts you've unlocked when you played Assembly Mode to create the custom gun of your dreams! You can craft a variety of unique weapons. Create big weapons such as shotguns, rifles, and even heavy-duty military-grade items, or try your hand at creating small pistols that secret agents would love to use!
