2D Gameplay Tutorial

hi everyone i was looking at this tutorial and my question is if i can use the tutorial assets of this tutorial http://unity3d.com/support/resources/tutorials/2d-gameplay-tutorial.html for comercial use

not really a programming question, but as far as I know, every free tutorial for Unity also is royality free - AS LONG as you use it for a Unity project. So you may not use the asserts in another Framework like UDK or similar.
