In an interview with IGN, Xbox exec Phil Spencer entertained the notion that Halo 2 Anniversary is coming, saying that in this hypothetical situation, the folks over at 343i would have to "nail" the multiplayer.
With a grin on his face, Spencer told the outlet:
In this fictitious world where that game existed, it’s an easy answer: it has to be just the multiplayer experience that we all found in that first Halo 2 game. If you think about what happened in the franchise and what were the hallmark moments – when did duel wielding come in, when did another playable character that wasn’t Master Chief come in?
All the things that you and I know about the evolution of the franchise, if you’re going to say one thing about Halo 2, you’re going to talk about real multiplayer. I think you just have to nail that in just such a fundamentally core way. Frankly [we'd have to do it] probably better than we did with Halo 1 Anniversary. I thought the multiplayer in Halo 1 Anniversary was good, but Halo 1 never had multiplayer in the truest sense, so it always was going to be something different.
If there were something called Halo 2 Anniversary, I think the multiplayer would have to be fantastic.
I don't know about you, but I am absolutely ecstatic after hearing this from Mr. Spencer. After the disappointing multiplayer of Halo: CEA that was basically just a glorified Halo: Reach map pack, I feared that Halo 2 Anniversary may take a similar approach, but based the words of Spencer, if a remake does come—which is all but confirmed at this point—we'll get the tried-and-true Halo 2 experience from the good old days.
