"Back in the early days, we talked a lot about The Magnificent Seven and The Seven Samurai," Lee Wilson, story and cinematics lead, said. "And yes, originally, there were seven Spartans.

Wilson described Rosetta as being "sassy," while Tom was "a cowboy." If you need us, we'll be pouring one out for the first casualties in the Fall of Reach.
