Sierra 117 is the second level of Halo 3 and the first level that involves real action. This is also the first level in where Master Chief has his "times" of the week. This level takes place in the lush jungle lands of eastern Africa. It's near 3 mountains, though nothing to worry, the mountains don't get angry as volcanoes. There is a scenery: waterfalls, bunch broken trees, and lots of Covenant retard corpses.
