King-owned Seattle-based studio Z2Live has cut jobs in its support functions group.
While the exact number of jobs cut is unclear, GeekWire reported that the studio was 100-people strong when acquired by King in 2015, but only 60 people on LinkedIn are listed as working at Z2 in Seattle.
"We acquired the Seattle studio last year and are now integrating it into our business and aligning it with our strategic goals," said a representative for King.
"We are removing some support functions and capitalizing on the experience and talent within the studio, so we can best deliver on our goal of bringing the very best games to our network."
This may be related to the recent decision to sunset some of Z2's back-catalogue of games, which will be switched off on 28 September.
What this means for the studio's currently soft-launched midcore title Rise of Tyrants is unclear, though it seems unlikely that the game will be outright cancelled any time soon.
