Mod DB has the release of the Jumper and the City modification for Crysis. This is described as a cross between Mirror's Edge and Prototype. Word is: "Feel the full freedom and the superman power in the Miracle City. Enjoy the new features such as gravity boots, gravity gun, slow motion and 3rd person camera." They also note that the mod is only compatible with Crysis 1.2 or 1.21, but they are working on a release for Crysis Wars to include extended gameplay and multiplayer support. Thanks Ant.
