That dude is seriously ridiculous. He didn't use any cheese methods as far as I'm concerned, just straight up killed it. Some people argue the invis is cheese, but that is a game mechanic and he's using it as intended. Hard to argue that's cheese in my opinion. My hats off. PS For any who don't know, this is the same guy that two-manned heroic VoG with his buddy pre-DLC (including soloing all of the portals on Atheon).
