In this final paper 3D augmented reality mobile game was processed. It was made combining Unity Engine and Vuforia software. The main purpose of the game is to defend sculpture which contains energy of life, while player needs to defeat all enemies (skeletons) and their boss (Diamond Lord). The player plays from the first perspective and can use four types of weapons (pistol, automatic gun, machine gun and sniper). The player movements are defined by moving mobile phone physically (using embedded accelerometer, gyroscope) in relation to the target (Image Target) which is defined by Vuforia software tool. This tool is implemented into Unity Editor as package. Defined scene is rendered after target (2D image) is recognized in the physical surrounding and that is the way of accomplishing interaction between real and virtual world. Despise using Vuforia tool, bunch of scripts were used for controlling objects which are coded in C# programming language. Graphics, user interface was made by using GIMP 2 software, while for making scenes the models were used. The models were downloaded from free-content sites, same as melodies and sound effects. During process of creating animations, embedded system of Unity, Animator was used. In order to save the results to the local base, JSON format was used, and implementation was accomplished using the SimpleJSON plugin. There are two scenes in the game. The first scene represents the main menu in which player can see current achieved results, setup settings and start with the game. The second scene represents level which is loaded, rendered when target (Image Target) is recognized. The outcome of level can be victory or defeat.
