Can schools use imagary from unreal for promotion?

We are in the process of setting up an online MA course in Game Audio. We plan to make use of your academic materials throughout the MA. Are we allowed to use images and game play of the free games in our own promotional material, e.g. a short video trailer of the course, or on our own website page describing the course?

Yes, you can use the sample content for those purposes under the EULA.
