In a recent play-through of Halo 4 on Legendary, I may have encountered a glitch on Midnight. Before Cortana portals you to the Composer, the portal may have a problem. As many crawlers came to attack me, I made it to the portal with the black screen and teleporting sound effect greeting me. However, a FRAME after I arrive in the next room, I am taken back to the previous, even though I had roughly a quarter of my shields left. I suspect a crawler must have killed me a mere second before I passed through the portal, but I have yet to see one suppressor or Boltshot kill me in that manner. It might have been my rotten luck, but the incident occurred twice and the same thing happened, leading me to believe it was a glitch. On a Legendary run for a player of my skill, this is very frustrating.
Can’t say this has ever happened to me
Never seen or heard that happen before. I’d reload the checkpoint or restart the mission, but I guess you could try again.
