A free app for Android, by Noble Empire.

World of Guns: Gun Disassembly is the ultimate weapon simulator for Android. If you have ever wondered how the insides of a Minigun work, or you want to know how a particular gun from your collection will perform, this is the app for you.

The aim of the game is to get as close as possible to a real gun while keeping the physical aspects of the weapon as realistic as possible.

The game also includes 10 shooting ranges with timed objectives, a paint mode to customize your weapon skins, and minigames and quizzes to try.
