After your Pelican crashed in the centre of Sydney; Australia, while the Covenant were invading the city, you woke up in the crashed Pelican…Fire everywhere, all the marines that were in the pelican were dead, 2 days…the city is now desolate and empty, destroyed and burned, you walk into a hospital building and you hear gunfire nearby, you run to the location, walking over and through halls of dead covenant till you walk through a door seeing Rose-B216 and her teammate Heresy-H202.
