Classic Halo gameplay that merges together with a Rogue One-esque classic war story of a group of comrades taking on increasingly insurmountable odds in service of a greater cause than their own survival.

Thought it helped to get across how futile and doomed the defence of Reach was and is only ultimately let down by some tedious mission elements or checkpoints that never materialised. I don't like the Hunters in any Halo game and the ones in this were especially irritating in a way I can't quite put my finger on.
