On November 29, 2012, it was revealed that, partly in response to a petition for the release of an HD version of the series' original trilogy, a group of fans had been given permission by Crytek to develop a "TimeSplitters" mod using CryEngine 3. The project lead, Michael Hubicka, stated that:""TimeSplitters 4" is our ultimate goal, but first we have to convince Crytek there is sufficient demand for the series through HD Collection."The game, named "TimeSplitters Rewind", will combine "greatest hits" elements from across the trilogy. The team have stated that, although the engine will give "Rewind" more of a modern look, they "didn't plan on fixing something that isn't broken." It is expected to feature both story and multiplayer modes and to be free of charge on the PC. The development team originally planned to develop the game using the Unreal Engine 4; however in 2017, they revealed an intention to instead use CryEngine 3, due to concerns that the Unreal version would be unable to "use the "TimeSplitters" IP and would likely have to re-brand."
