HA! you just changed that pic in photoshop dude, nice try. I'm sure you didn't just grab different pics from Moon and splash em all together. There is no night bus, it ain't in the game's coding, don't believe me? go ask one of the hackers who proved this countless times. The bus driver proves that its photoshopped, the glasses stand out further than the sign saying night time *******, yet another fake.
Look at the gun, the front of the bus overlaps it a little, furthermore stating you put it together in photoshop. sheesh, one in a million little kids trying to act clever, again.
Ok, I overeacted, but I've seen quite a few posts about this night bus. Your way is impossible unless you noclipped, you cannot get access to the power station without killing some zombies dude. Funnily enough there was only one night bus thread that was in a way "tempting", so I went ahead and did it with my mate but nothing happened and half his steps were just impossible to do without hacking.
Your picture did not prove anything mostly because you can type it in on google images and its there. If you want to really prove it then put up a vid of your gameplay or else your thread is just a time waster for you and others. The image was fake, its just that simple to realise it if you use photoshop commonly, which I do very much.
