Halo
Alternate ending sequence:
Successfully complete the last level of the game in campaign mode under the legendary
difficulty setting. The new ending features a human and alien fighting hand to hand.
The human will say "Its over", and then they hug because they know the explosion will
kill them both. Also, the FMV sequence of each battle scene will be slightly longer.
Alternate dialogue:
Playing under the legendary difficulty setting introduces new dialogue not heard in
other modes. For example, after being massacred by a force of Grunts, Jackals and
Elites, one of the grunts asks, "Can I have his helmet?". Also, your fellow Marines
seem to be a bit more chatty (as well as profane).
Under the legendary difficulty setting, view the entire first FMV sequence. During the
sequence, the General says things very differently when compared to the sequence under
the easy difficulty setting.
