Bungie made fantastic live action trailers for Halo 3, ODST and Reach. They were so good I still watch them occasionally. If 343 wants people to get engaged in Infinite before its release I think they should invest in one as well. They become videos you can send to friends and say “THIS is why the games and books are so enthralling. This is why I think you should try Halo.” The funeral in the ODST one was striking, and the part with Noble 6’s sacrifice after Kat loses her arm in the Reach trailer are still great to watch.
I’ve loved such things previously.
But 343 have painted themselves into a corner. Halo Infinite needs to show off it’s gameplay and mechanics. The narrative needs clear focus. I think anything live action or CGI at this point will only come back to bite them.
