"Because we made the decision early on to decouple sprinting and suit energy, it allows us to create bigger running environments. So it was no longer a case of, you know, all jumps must be able to be made by sprint power jump and also normal jumps. You could actually just make these vast expansive environments where free running became a big part of it. You’ve got your vault mechanic as well. It’s not just the ledge grab from Crysis 2, which allowed you to get higher up; this also just allows you to interact with the environment. It doesn’t mean we have linear rooms anymore. It means that if you think you can get over there, you probably can. It allows us to create more versatile environments" -Adam Duckett (Crytek)
