do you need to download anything before you can play halo 4 mulitplayer? I heard someone on the xbox talked about it
Halo 4 comes with two disks.
I believe you need 8GB of space to install one disk so you can play campaign and multiplayer on the other.
There may be a few MB patch on release, but you install the second disk containing the MP content. If you don’t have capacity remaining then there is still time to pick up a 16gb usb flash stick from amazon for around $6-8 dollars.
