That rumor on 343 Industries working on an Anniversary Edition of Halo 2? Bollocks.
The developer has come out to squash the rumor, saying in a recent Q&A that they “are not working on that at this time.”
“We are kind of busy.”
That means Halo 4 then, the game they have prove themselves with as a studio worthy to take over from franchise creator and long time developer Bungie. No pressure.
