The former studio head of Call of Duty: WWII maker Sledgehammer Games Michael Condrey (pictured) has said that there were certain aspects of development that the firm had control over.

Responding to enquiries about Call of Duty matchmaking on Twitter, Condrey said that the studio had "frustratingly little influence" over sizeable parts of game experience, including analytics, matchmaking and monetisation. He said that these were decisions that were made by US publishing giant Activision.

"Analytics, skill-based matchmaking, monetisation, dedi server coverage, etc all driven from ATVI central tech and production teams," Condrey wrote.

"Frustratingly little influence on those corp decisions despite their impact on our games and the COD community."

Condrey was replying to complaints from former Call of Duty pro player Matthew "Nadeshot" Haag about the series' skill-based matchmaking system while also not having a ranked play mode.

"I’ll never understand why Call of Duty goes through all of the trouble to implement skill-based matchmaking but won’t add a ranking system," he said.

"If you’re going to match me up against better players, why can’t I have a rank to be proud of and work towards?"

Condrey departed Activision after he and fellow Sledgehammer boss Glen Schofield moved to exec positions at the publishing giant in December 2018. Little was heard about these roles, but Condrey left and was named as the head of Take-Two's new 2K Silicon Valley studio in February 2019. That outfit was named 31st Union in February of this year.

Meanwhile, Schofield is heading up PUBG Corp's new San Ramon, California-based Striking Distance studio.
