Here is a glitch that I think should be put into its own category. I don't have a way of replicating the glitch at this time, but I think it would be a game breaking change to the current categories. If a way is discovered to replicate it then a ng+IS and a ng-IS category should be created (IS for infinite shot)

tl;dr potentially replicable glitch would remove most skill from FPS/TPS portions of the game in ng and ng+ so it should be a different category.
