The social games development company - who created the free-to-play match-three puzzle video game - are seemingly working on the first-person shooter after they advertised for a level designer to work on an "exciting new project" in Sweden.

The advert said: "The aim is to create a 'Call of Duty' experience on mobile, while also breaking new ground for mobile and redefining the genre.

"The approach and ambition is to be fresh, social, and highly accessible, while providing a very authentic game experience."

However, King have a strict criteria as they have explained the ideal candidate will have experience working in the shooter space and have "some understanding of the casual and midcore markets."

They are also looking for a senior network engineer and a senior tools developer.
