Herobrine has been rumored to be in the X-BOX live Arcade version for a short time as well, before it was updated in July. rumors include strange deaths (In Game), random arrows, ect ect. These are all Coding bugs because 4J studios have a very early edition of minecraft 1.6.6 (I think that what they began with), but have since updated and removed a lot of these bugs. It is not Herobrine. Even though he is in the minecraft enemies Picture pack (X-BOX) and he is quoted in the loading screen he isn't real and never has been. If you here block noises randomly in caves or above ground while you not walking and no mob is around, these are audio glitches that happened ALOT in beta on the PC version, and will most likely be in the X-BOX version as well. He isn't real. He never has been. I cant quite explain why he keeps reappearing in the patch notes though. This could be Mojang Trolling, and most likely is.
