"Boss Fight" Ideas

[Zaari]

Because I do not want to have a bland ending. I can imagine a boss battle would be out of the question, but I can't think of another good way to end the map.

You could make some sort of "rush" to the ending, like in Justine with the final suitor chase.

EDIT: Also, be sure that you have a well written story and try to make it strong in the end. That always makes for great endings.
