Even though "Halo 4" was hailed as a critical success, game developer 343 Industries was not completely happy with the final product and stated that there will be improvements for the next game in the series.

Frank O'Connor, the development director for the franchise, stated on the blog Halo Waypoint that lots of mistakes were made during the production of the latest game.

"[Halo 4] wasn't flawless by any stretch of the imagination," read O'Connor's statement. "But by most objective criteria, it was a resounding success. So we know we have a lot to do. And we know we have a lot to learn. But we also know that we now have the capacity, the teamwork, the technology and the experience to do much better next time."

O'Connor stated that the game was not completed to its fullest potential, adding: "We made a lot of mistakes. We can do better. And we know this, and we will."

What exactly were the mistakes that O'Connor perceived were in the game?

"There are a ton of things we wish we could done better," O'Connor elaborated. "Features that didn't make it into the final game. Glitches that emerged. Missteps made. DLC fiascos. Communication breakdowns."

There were aspects of the game that O'Connor said were very successful. Most of the accomplishments included the overhaul of the game engine and great teamwork from everyone that worked on the project's development.

O'Connor may not be completely happy with how it turned out, but Halo 4 was one of the best reviewed games of last year with an 87 aggregate score from Meta Critic.

The only real information currently known about the next Halo title is that it will be "darker" than the previous installment. Rumors indicate that the game could come out with the launch of the Xbox 720, but with the recent release of Halo 4, the next title is likely a few years away. Reports have claimed that the title is in early development, according to GameRant.
