In this section, we'll add the final touches to the game. First on the agenda is to fix the game background! Until now, the background has simply displayed the default background color associated with the game camera. However, as the game is set in space, we should display a space background. To do this, create a new Quad object in the Scene that'll display a space image. Navigate to GameObject | 3D Object | Quad from the menu. Then rotate the object and move it downward so that it displays a flat, vertically-aligned backdrop. You may need to scale the object to look correct. See Figure 4.39:
