title: Load two scenes at the same time at runtime
body: <p>I have two scenes. One with a map and one with Buttons and stuff. <em>(A little bit like a UI scene)</em> How can I load the two scenes at the same time at run-time via script?</p>
  
  <p>I think I need something like <a href="https://docs.unity3d.com/ScriptReference/Application.LoadLevelAdditive.html" rel="nofollow"><code>Application.LoadLevelAdditive</code></a> but it's obsolete.</p>
