High Charity is the fourteenth and penultimate campaign level of Halo 2. As John-117, you must battle your way through the Flood-infested High Charity to stop the Prophet of Truth before he boards the Forerunner Ship. This is the last level you get to play as John-117 in Halo 2. This level is also the only time when Master Chief sees the Flood in combat in Halo 2, and also the only level in the game where you have no allies aiding you. It is also the shortest (playable) campaign level. You can find the Iron Skull on this level.
