Switch to Unreal Engine:
At several points over the past decade, management at 343 debated switching to Epic Games Inc.’s popular Unreal Engine. But it wasn’t until late last year, when previous studio head Bonnie Ross and engine lead David Berger departed and Pierre Hintze took over, that the firm finally decided to pivot to Unreal. This switch will start with a new game code-named Tatanka, according to people familiar with the plans. That project, which 343 is developing alongside the Austin, Texas-based game studio Certain Affinity, started off as a battle royale but may evolve in different directions, the people said. Future games in the series will also explore using the Unreal Engine, which may make development easier, although internal skeptics are worried that the switch may have a negative impact on the way Halo games feel to play.
