I see demo 2 and 3 are pretty much the same. I have watched demo one (no number in brackets) before and have commented on this video. In Demo One I see no evidence of wall hack, I see every kill moose make and some he missed, I again found myself telling him to turn in the direction of sound, but he doesn't, guess his sound is stereo only. Throughout demo one moose is texting with that annoying The Weekend, a player who likes to spam the chat with nonsense, and misses obvious kills due to his slow typing skills (I cannot bash him as my typing SUCKS). Demo two and three in Crossfire, again, IMHO, show zero evidence of walling. I see enemies running past windows to pop out at exits, I see people kneeling in nooks when he jumps, I see all of his kills but no evidence of a wall hack. When he is hiding at the top of the stairs and gets three or so kills in a row, I see them all, this is where Orion states "See that one?" even here I see no evidence of walling, or any type of tracing or pre aiming or anything. He gets his ass handed to him by knucklehead and -cro- for most of that demo with kills on moose coming from them that I was surprised by. Anyway, these demos, again, IMHO, show that moose is clean, and a slow typer with stereo sound.
Looking forward to hearing others opinions.
