It's been a while since many players outside of its dedicated community heard about Halo, and the latest piece of news surrounding Xbox's flagship title isn't good.
According to several trusted sources, Xbox canceled an in-development Halo spin-off that was reportedly codenamed "Project Tatanka." This unannounced project was planned to be a battle royale off-shoot and was in development by Certain Affinity, a studio known for its collaboration with 343 Industries on various Halo titles.
Project Tatanka started life as a battle royale mode for Halo Infinite, but over time it evolved into something more significant. This evolution of the project led to speculation and excitement among the Halo community, who were eager to see a new dimension added to the beloved series. The project, according to Bloomberg's Jason Schreier, had shifted significantly during its development and possibly evolved into a different kind of game altogether.
The cancellation of Project Tatanka was first brought to light on the XboxEra podcast by industry insider Shpeshal_Nick. This revelation was then independently confirmed by co-host Sikamikanico. According to their sources, Project Tatanka isn't in active development anymore. Additionally, Shpeshal_Nick mentioned during the podcast that he had received info about another Xbox game that, if announced, could cause plenty of drama. However, he chose not to disclose this game publicly to avoid potential controversy.
