A topic such as this can normally be contentious, as many people may find the idea of Killcams traced back to the player who did the deed to be frustrating. However, what isn’t new about the Campaign mode of Halo, is where it will always show players how the Master Chief dies.
Since people can (and will continue to) post videos of their best kills, would 343 consider adding a “kill shot” feature, which would show how a player dies, from a 1st-person perspective of a weapon, grenade or vehicle?
