In the tutorial, if you go into the models folder then open up the character, you will see animations with play icons. How did these get there? Are these FBX animations just dropped in as the children of the character?

Survival Shooter is using Unity 4.6 since 4.5 they improve a lot in the UI.

I found the info to import your character and hook up animations in this tutorial:

You have to read all the options. There is a workflow with all the animations in one file or all the animations in different files.
