Combining two scenes?

Unity Engine
1

I have two scenes (main menu and core game scenes) in which I need to combine both of them.
So if I click play on the main menu screen, it will transition to core game scene.
An example would be like jetpack joyride.

Any idea on how to do that?

thank you

I think you are looking for Application.LoadLevelAdditive. If you are using Unity5 use Application.LoadLevelAdditiveAsync so the scene doesn’t look like it freezes when you are loading the new scene. Hope this helps.
