This is the third-person shooter game as instructed by [the Unity tutorial] tutorial video series.
The player is a space ship which can shoot incoming asteroids. It is a simple game which repeats endlessly until an asteroid collides with the player.
The main goal of this tutorial is to provide an example of how to incorporate pre-built assets, both graphical and aural, into a Unity project. It is common practice for Unity developers to work with provided assets.
