No, players will not be able to play as an Elite in mutliplayer mode in Halo 4. Confirmed by 343i.
no but cortanas look should change because many ages play halo 4
There is no HALO 4, but If you're talking about HALO ODST, yes, you can play as a human and make your face visible in Firefight
Not exactly. Instead of a Halo "4", Bungie have decided to release Halo:ODST. This game bridges the gap between Halo 2 and Halo 3. You play as an ODST marine in the game. Also, for RTS fans, Bungie have also made Halo Wars, a strategy version of Halo, in which you can play as either the marines or the covenant.
no, only xbox
Aside from hacking, you can't.
You can, but you will not be able to play them, unless a friend brought it over, per se.
No, unfortunately. The Halo series has always been an Xbox exclusive.
