another FASTER way to bxr is to shoot off a burst already hold down the right trigger and press the reload. YOU HAVE TO KEEP THE TRIGGER DOWN. go up to someone press b then x and release the trigger and you'll unload faster.
majority of the people who think that button combo's, and superjumping is "cheating" are the people who either A) can't do it or B) can't do it as well as others.
superjumping is a design flow in the text coding of halo 2, and they even promoted it in one image they had in egm. (before the map pack came out, they showed pictures of them being on top of the snow level, i don't remember the name of it.)
button combo's are found out from people who actually sit on the game for hours and just mash buttons in customs.
it's not like they bought it online and installed it on there xbox. they learned it and practiced it. tough cookies you don't want to sit down and learn a few buttons and someone else does.
