[quote]Is there any way to transfer my access to any of this content that I should already own or will I have to buy another expansion pass for the XB360 copy?[/quote] You will need to purchase another copy of the Expansion Pass if you want to access Expansion content on your Xbox 360. The license does not transfer from Xbox One -> Xbox 360. Furthermore, the pre-order red sparrow, shaders, and Collector’s Edition exclusive codes are platform specific and cannot be transferred.
