LittleBigPlanet HUB is an upcoming free-to-play PlayStation Store-Exclusive title for PlayStation 3. It was originally going to be released at the end of 2013, but was eventually delayed.
Small sections of LittleBigPlanet and LittleBigPlanet 2's Story Modes will be available to HUB players - as well as a LittleBigPlanet HUB-exclusive Story Mode. LittleBigPlanet 2's Team Picks will also be available to play on LittleBigPlanet HUB, however it is not yet confirmed whether players will be able to play other community levels from LittleBigPlanet or LittleBigPlanet 2, or whether LittleBigPlanet HUB will have a separate online server to the aforementioned titles.
Players will not need any of the previous LittleBigPlanet titles to be able to play LittleBigPlanet HUB, however, if a player has collected items from either LittleBigPlanet or LittleBigPlanet 2 they will be imported over to LittleBigPlanet HUB.
As there has not been any confirmation that it is still in development, the game was most likely cancelled. Several of its features have been added to LittleBigPlanet 3. Update 1.22 of LittleBigPlanet 3 added Challenges and the Seaside Surprise Level Kit, which is supposed to be the free level that came with LittleBigPlanet HUB.
