it is posible to get the terminals os halo 3 in the extras/videos of mcc collection? in the same way that the ones in halo ce, 2, 4?
Probably not, given that the H3 terminals are in-engine and mostly text. Terminals from the other titles are all pre-rendered.
I agree with Carnage. That said it would be a fun idea.
In the meantime though if you are looking to re-read them all at once they are online. https://www.halopedia.org/Terminal_(Halo_3)
After thinking about this some more, they could just add the text transcripts of the terminals instead of the in-engine presentation of it. They could even go the extra mile and add transcripts for the Reach and H4 data pads.
