Moon Spy Secrets (HELP)

[Dextral]

Hey,

I know there are 'secret' rooms in the orokin moon spy missions similar to that of the orginals that give drift mods, anyone have any youtube/reddit/forum links to help someone complete them. As im having issues finding any, i know how to complete the 'vaults' (A,B,C). Just not the secret rooms that have a chance at rare containers

Thanks

This video (not mine) shows the room with the rare container in it.  Activate the control panel and watch what sound tiles light up. Step on the tiles in the same pattern.
