That wasn`t a BXR. If you look closely, he shot before he punched, and it just took a bit to register (online lag). There IS a bxr in halo 3, but it`s LAN only. The combo is R-R-Y-B (on default settings).

if he beat him down why did it say killed him instead of beat him down

first of all at 5:23 all he did was beat him down....there was no BXB, the players shields were lowered.....and last that D3mond DDDDD is a BEAST, he is a big reason why they are so ``RAD``

Yep he bxrd theres a halo 3 bxb and bxr

what did he do at 5:23 i wanna kno dammit
