Star Trek: Deep Space Nine: The Fallen

The Fallen is a third-person shooter. The player can choose to play through the entire game as either Captain Benjamin Sisko, Major Kira Nerys or Lt. Commander Worf. The game does not repeat levels, however; different characters must complete different levels. As such, depending on which character the player chooses, the game is very different, and the entire story is only revealed when the player completes the game as all three characters. (wikipedia.org)
