The Question that's been asked a million times...

What is the deal with the multiplayer maps?

(A) Do you install them on your HDD and play them with the Reach disc? Able to share them with your friends as well (similar to the Halo 2 MP disc).
(B) Do you run them off of the CEA disc and become unable to play any other Reach maps unless you disc swap?
(C) Do you get a one-time use code to download them?

I thought it was (A) but then I’ve recently heard things about disc swapping.

Can this be sticked as well so that someone else (which I’m sure thee will be) doesn’t have to make another thread like this.

A: You can install them and play them with your HDD with the other Halo Reach maps, but i don’t think that you can share them with your friends…
B: From the CEA disk you can play only these 7 new maps, if you want to play them with only one disk and with the other Reach maps you must install them on your HDD.
C: There will be a function to install them without any code.

I hope that i helped you.
