"long before" those Infinity Ward troubles flared up. It's all they do now.
This has led to a "dedicated multiplayer team" being formed at Treyarch, to help shape the online experience across all their Call of Duty releases.
"Treyarch is a 100 per cent Call of Duty studio and it has been for a long time now," Lamia told , "long before any" of that Infinity ruckus happened.
"We focused all of our efforts on creating the best Call of Duty game we possibly can and what that meant is not working on anything else. We are a multiple team studio and focusing on Call of Duty and Call of Duty gameplay meant focusing all of our teams on that."
Call of Duty: Black Ops releases on Xbox 360, PS3 and PC November 9th.
