Can anyone direct me to where I can view the Halo 4 terminal videos in Waypoint? I have found all the terminals in game, but I have no idea where I can watch them in Waypoint. Any help is appreciated.
I’m not sure about the waypoint app, but on this site go to Career > Halo 4 Stats. Then on the side click Campaign, Then scroll over then scroll down. 
go to campain section in your halo 4 career and pan left
Had the same question myself, and after doing some digging, I managed to track them down. Find the portrait of your Spartan, click on the career tag on the right of the screen, and the menu with all the videos is on your left.
