I looked at that picture a good 30 seconds before I noticed the MC was in it, LOL.
Continuing the theme of live action Halo commercials, not that big of a stretch is it?
Yeah I think it could be real as well. During the lead up to Halo 4, they talked a lot about why there were doing Forward Unto Dawn was because fans like live action Halo, they love the commercials. It makes sense they're filming a live action commercial now, so that it's ready in about 6-7ish months to hype up H5.
