Halo 3: ODST (in other times, Recon) will have as main character a ODST troop and it will have some flashbacks. The main goal of this trooper is to save his squad.
While we’re pursuing his goals, the game will be a little bit open-world. Once you find the clues that leads to your teammate, the game switches things up, you get a flashback and then you'll play it.
Joseph Staten confessed that every squad mate has a “very distinct personality”. "The reason we decided to keep the rookie faceless and anonymous is to help smooth these clue-triggered transitions from one ODST to another," says Staten. "[The game] is designed to put you in the boots of a bunch of fun, memorable characters so you can experience this awesome pocket of Halo fiction from as many points of view as possible."
