The retail training program, ExpertZone, leaked information on Halo 4's episodic campaign - Spartan Ops. Now, a Q&A session with the developers has leaked from the same source.

One user asked about the ranking system in Halo 4, citing Halo 2's 1-50 implementation which was without boosters - people who played in teams with less skilled players, to artificially rise the level - and it was therefore hard to reach the higher levels. In Halo 3 the aforementioned cheating emerged, and there was no 1-50 implementation in Halo: Reach.

"We have a different career progression model in Halo 4 that spans traditional MP as well as Spartan Ops. It should be a satisfying measure of experience AND skill, but we will have more to say about that and stat tracking at a later time," 343 Industries said.

Another question was two-fold: how are the developers keeping aspects from past Halos intact, and will there be a Legendary Edition of the game?

"Honestly, the "feel" and "soul" of the game are vital. We're adding, evolving, building on those foundations, but we're respecting the heart of what makes Halo feel like Halo. And there's no Legendary edition, but our Limited Edition is an amazing value - tons of content, tons of variety, and a very cool package," the developers also said.

It has been rumored a Halo 4-themed Xbox 360 console will arrive: when a user asked community manager Jessica Shea on Twitter whether other versions of the game would arrive, she said the company isn't talking about other editions ... for now.

Neil Davidge, of Massive Attack, the composer on Halo 4, also said in an interview during E3 2012 he's given an overview of a level and composes what he thinks will fit.

"Neil continues to work with us on the actual scoring, rather than simply the original composition - but the game content changes so often that scoring "live" is impossible - so Neil creates themes for levels, characters, moments and then we work with those compositions to have them appropriately scored and fit," the developers added.
