Narrative Object: Radio broadcast

This is a tough one to find, as it won't be marked with the bookmark signifier that most Narrative Objects have. Find the radio on the info desk at the far end of the lobby (near the ammo backpack). Then, you'll have to use Time Vision and hold Y to extract the broadcast from the time stutter.
