'Call of Duty: Black Ops 4' won't feature a traditional campaign because working on the franchise is "a journey".

The upcoming game is making a move away from tradition, and developers Treyarch has explained that they don't want to be tied down, instead choosing to explore other ideas freely.

Speaking to Game Informer, co-studio head Dan Bunting said: "Development is a journey. We try a lot of different ideas and a lot of different things. The game that we are making has evolved over time, and that's just a part of development.

"I can't remember a single game that we've made that hasn't had a dramatic change in the prototyping stage. That's what prototyping is for.

"You prototype ideas; some of them work out great, some of them don't work out great and you pivot. You find a new idea [and] focus on that. We follow the fun."

It seems the company had always wanted 'Black Ops 4' to be a social experience for gamers, and it's worked out well that the decision to axe the traditional campaign came at the same time they explored a battle royale mode.

Bunting added: "Everything tends to work together for a reason. Internally, we have built a culture of adaptation. The most important aspect of game development is being able to adapt.

"If you can't look at something that you're doing honestly and say, 'This thing isn't good enough' or 'This isn't what we want,' and 'We need to make a change.' If you can't do that yourself, then you're not adapting. You're not going to evolve in a way that's going to constantly deliver exciting experiences for your fans."
