The first-person shooter has evolved so much since its announcement that the development team has decided to move away from the Brothers in Arms franchise, reports Kotaku.
Likening the shooter's combination of gameplay styles to Borderlands, Gearbox head Randy Pitchford said that ditching the Brothers in Arms title enables the team to "go wild with new features".
"Our Pokémon has evolved. It has different powers," remarked Pitchford.
More details, such as name and release dates, are expected to be announced at a Gearbox community day on September 15.
Brothers in Arms: Furious 4 was first revealed during E3 2011 and was recently assumed to be cancelled after publisher Ubisoft pulled trademarks for the game.
Set during World War II, it follows four soldiers who face an "experimental Nazi army conceived in secret" while attempting to track down Adolf Hitler.

The team had previously refused to comment on its status until they knew exactly where the title was heading.
Gearbox Software's next project, Borderlands 2, will be available on September 18 in North America and on September 21 in Europe.
