The leaks are said to have originated from Halo Studios' (formerly 343 Industries) long-running collaboration with modding team Digsite, which has been excavating scrapped content and old files before adding them back into the classic FPS games. Halo 2's infamous E3 2003 demo was recreated and modded back into The Master Chief Collection just last month, for example, as was an Arbiter mission that never crossed the finish line two decades ago - all of which were reconstructed with official design documents leftover from the Bungie era.
