New Easteregg

Science Recon, ZenzineZ, Nowise10, and I (Cheaf Min) found the 3rd part of the easter egg on mission 10 of the halo 5 campaign (2 waves of normal knights, 1 wave of big knights, 1 wave of little knights, and another wave of big knights) and were wondering if that was all of the easter egg or not. So if a dev or something could tell us we would appreciate it.
