The fourth and last expansion called Rise of Iron released in September 2016. In December 2015, Destiny shifted to an event-based model, featuring more periodical limited-time events. Upon the release of the third expansion, retailers issued Destiny: The Taken King Legendary Edition, which included Destiny and all DLC up to and including The Taken King. The third, The Taken King, was released in September 2015 and had the largest effect on the game, as it changed much of the core gameplay. The first expansion was The Dark Below in December 2014, which was followed by House of Wolves in May 2015. Each package of downloadable content added new player versus environment (PvE) missions and player versus player (PvP) modes, new locales to visit, and new items for the player to make use of. There are four pieces of downloadable content (DLC) that were released for Bungie's 2014 first-person shooter video game Destiny.
