How does noble 6 die in halo reach

you (noble 6) die in mission lone wolf. you fight until you run out of energy. when you do, the movie clip rolls: you get under heavy plasma fire, get in close combat, kill several elites, get pinned on the ground, and stabbed by a plasma dagger. you die saving the pillar of attum with the master chief. the game ultimately leads into the first halo.
