An izlom is a mutated human that was supposed to appear in S.T.A.L.K.E.R.: Shadow of Chernobyl.
An izlom walks on all four, has one arm much longer than the other arm and has a very long neck. Izlom are not aggressive, they tend to avoid engagement with stalkers. They rarely attack unless one is too close to them, when they do attack they are quite fearsome with maddening zombified moans and they use their large arms to both block and beat the target up. Izloms appear to be neutral with Snorks, but hostile to Bloodsuckers.
The creature appears neither in Shadow of Chernobyl nor Clear Sky prequel. Its concept was abandoned by game developers in the early stage of game development, but several game assets were retained inside game data archives, so modders were able to recreate the mutant for the original game. They are referred to as "Fracture" in game scripts.
However, in Call of Pripyat, if you download a mod call SMRTER Pripyat, Izlom will appear in any area in the game.
