I read a little about this guy's videos on HIH and apparently (not sure if It's true), he uses mods, edits videos and stand-bys to make it appear he is doing this stuff. If you watch one of his earlier videos, he claims getting outside the death barrier on Valhalla, yet there are a few inconsistencies in the video which suggest that he copy-pasted parts on to make it look like he was outside and alive - such as in said video, he glitches his gun to freeze as part of the glitch. When it is frozen it still reacts to light and the compass needle reacts to direction, but once he is "outside the death barrier" his frozen gun does not react to light or to direction change. That is not to say that he never did this stuff or that you never did this stuff, it is simply a warning that this guy may well be a faker.
