Halo: The Master Chief Collection doesn't make it absolutely clear, the four-game collection featuring Microsoft's cyborg hero will include the multiplayer customization mode, Forge.
"Forge Mode is in there," 343 Industries Franchise Development Director Frank O'Connor tells Joystiq, adding that preservation for the collection is a top priority. Forge Mode allows players to drop in-game assets into emptied multiplayer maps to create new structures. In Forge, players can also alter properties of their created maps to developer new game modes.
O'Connor also assured us that the collection will also feature saved films, for Halo 3 and Halo 4, and for the first time, Halo 2.
