This is the first time i’ve encountered this. Is this a known exploit? I’ve been playing regularly and never run into this.
Here’s the pictures I took of both of them after the match was over.
Having no head is not normal, but in Halo it is.
Modding, not even once.
You can private message BS angel here or send a message to 343i @facebook/twitter (or whtever it was). They will take of that guy.

Since the dawn of Halo 4 the headless ones have used their unatural evolution to gain a advantage over standard players.

Oh no, it’s a new Flood form!
Switch to pistol. 3 shots in the body. After the game report them and get a different lobby. If you lose, its one game not the end of the world
I’ve personally never experienced this, and hopefully I never have to.
modder
I’ve experienced this the other day. It’s not a glitch, it’s a mod. I even tried putting the gamertag of the modder on the forum to have 343 ban him, didn’t work out so well.
I’ve played those two 5 times in the last week 
If any of you encounter such players, please File a Complaint on them in-game, and consider PMing their gamertags to bs angel or rukizzel.
Do not post their gamertags (or other identifying information) on these forums, as that violates our rule against calling out. We don’t want witch hunts starting here.
Would PM’ing angel actually do anything? Everyone has been running into these guys for over a week and reporting them in game. I suppose eventually the complaints will catch up to them and the accounts will get banned.
Too bad they are on one months and will just make new accounts ; unless their consoles get banned.

Or report the player to BS Angel.

A while back, I saw an official post on this very forum stating that such accounts are indeed being banned. If you like, I can try to track it down for you.
