Yes
13 campaign, no real story line tho.
In the BTEA there is 4 player split-screen, but that is all that is announced. But like all other Halo games there will probably be 4 player max on campaign, and 16 player max in custom games and matchmaking.
The Xbox 360 has an advantage over all other systems: Multiple accounts. If you want to start another campaign, simply create a new account on your Xbox, then put in Halo 3 and play. It will save data to that account, and allow you to have multiple campaign save files.
Yes. There are nine skulls, one on each level and there are 4 secret skulls on the levels Covenant, The Ark, Crows Nest and Sierra 117
Yes but only if you beat Halo 4's campaign on Legendary. I suggest co-op. That's the easiest
