I want to know
The terminal videos are done by The Sequence Group, not Blur (as far as we know). Although, it looks like some of the terminal videos are in fact CG.
They have the same artistic style as CEA’s terminals. They’ll probably be unlocked then streamed through Halo Channel.
I wish the terminal were something that would not appear right away for you like in halo 4. that if you want to see them, you could at a later time
The terminals are going to be the same as in CEA instead of the ones in Halo 3. They are videos instead of text.
Once you find a terminal, Halo Channel can be snapped in to watch it. The terminal videos were made by Sequence, and have a more cartoony art style to them.
