Just a very quick question. I saw that a weapon simply referred to as a “knife” is in Halo 4, according to the “confirmed” post.
SOMEBODY PLEASE TELL ME THAT THERE ISN’T AN AUTOMATIC KNIFE BUTTON.
Knifing is one of the few reasons why I can’t stand the CoD series and play Battlefield 3 instead.
No, it means that assassinations are back, although 343 hasn’t explained exactly how they will be implemented. 
Hope this helps.
Knife as in using a knife in an assasination.
Thank you!
If knifing became part of the game I would buy it and play it a lot still, but eventually rage-quit the game for like a year.
