Will I have to unlock all my Reach armor again?

If this is running Reach for multiplayer are we all starting out at default again or will our unlocked armor from Reach carry over?

you will still have your armor for the multiplayer

yes 343 made that very clear at pax 2011

If you haven’t figured it out by now, then No, you got to unlock all of your armor again.
If you have, then yes.

Of course. All of your data will transfer because the multiplayer is Reach.
