Can Blender Files Be Used With Unreal Development Kit?

I just found out about the Unreal Development Kit (UDK) on YouTube. I know it’s used to create 3D graphics too. I just wondering if Blender files could be imported to UDK, or vice versa. I hoping to use another game engine with Blender. I know that Blender already has one, but I always like to have more than just one option. :smiley:

Thanks Richard. I’ll check it out.
