Master Chief: War is a action-comedy Machinima filmed with the Halo 3 engine, created by Machinimator GuitarmasterX7. The latest and possibly last installment in the Master Chief Series, as well as the longest, totaling up at eighteen minutes and a half, this certain video is hailed for its jokes as well as its editing. As stated in the credits, GuitarmasterX7 does not intend to continue the Master Chief series, but he may pick it up once more and continue the series later in the future, as it has not be formally announced that the series has come to an end.
