Treyarch studio head Mark Lamia, has said that Call of Duty: Black Ops online multiplayer will always be free and believes you don’t need an Online Pass to compete with used games sales.

Speaking with MCV, Lamia focused on the fact that the multiplayer is included with the game you buy, and there won’t be any need for a download code to play it.

“I want to take that in the other direction and bring consumers really great reasons to keep their games, rather than trade them in,” Lamia said. “Multiplayer is critical to the success of this series. It has such tremendous staying power – there are millions of people playing Call of Duty every day.

“The effort that goes into the multiplayer is a living thing – we have a team that continues to work on it for World At War. We’ve done that for a long time and expect to do so for this game.

“We’re going to support the hell out of Black Ops. That will be our focus post-release: making sure we keep our fans engaged, and hopefully as a result, they’ll want to keep playing our game and won’t want to trade it in.”

Look out for Call of Duty: Black Ops is out November 9 for Xbox 360, PS3, PC and Wii.
