Finally finished Halo 5: Guardians with a good friend and saw one of the Elites do this. I didn't experience any game breaking bugs but thought it was interesting to see, I was not expecting this to happen. That being said, I am glad I have finished the Halo 5: Guardians Campaign. I am not sure why it took me this long to complete it but I am glad I have now completed the Campaign. Looking forward to playing more co-op playthroughs with friends.
