The project is about making a 3D interior game named as Gurkha Army. Interior game implies that the game starts and finishes somewhere inside a room remaining within the premises of a building during the entire course of the game. In first person games, the camera is positioned such that it gives an illusion that the player himself is traversing inside an environment. Likewise, in this project, the protagonist is a first person who navigates inside a building. The game progresses by handling the key events generated by the end user who simulates the first person actions.
