Assuming your question is “Will Unity delete the previous scene when it loads the new one?”, yes, it will. If you want to keep the previous level loaded (so the new one is added to the scene), use Application.LoadLevelAdditiveAsync("SGC Alpha V01.0"). Please note that additive and async level loading requires a Unity Pro license.
Or if your question is when will Unity load the level, the answer is in the documentation: LoadLevelAsync will load the level and apply it immediately after loading. I believe that currently it’s impossible to preload a level but only switch to i in a later moment. If you were to go the advanced (but free) way, you could:

  • Store your levels in a file
  • Load this file sometime in the game
  • Destroy all objects in the current scene
  • Apply the loaded data to the scene, instantiating the new level

This is rather advanced because you’re basically creating a level system from scratch.
