The Halo 2 BXR, Double shoot and Double Melee have been found in Halo 4!
They're a lot harder to do so practice is important.
DOUBLE MELEE
RB-X-L-Y-Y-RB
(Push X and L at almost the same time)
*Don't push XL too fast or else the first punch will not do any damage
BXR
RB-X-L-Y-Y-R
(Push X and L at almost the same time)
*Same type of trick as the previous glitch
DOUBLE SHOT
R-X-L-Y-Y-X-L-R
(Push X and L at almost the same time)
*Different than the others
^ That last one is really really hard to do so I don't think it will actually affect multiplayer but the BXR is something that should be fixed.. :l
