Treyarch has insisted that players will be shocked by Call Of Duty: Black Ops' multiplayer reveal.
Community manager Josh Olin said that the studio's full commitment to working on the game has allowed for some surprising features to be included.
"To be completely honest, I think that the players are going to be very, very shocked when we reveal our stuff," he said.
"I don't think they're going to expect this out of Treyarch, because we just haven't had the time or resources to do something like this. If you look at the size of any other studio that works on two-year development cycle on a first-person shooter, and compare that to Treyarch, we are a Goliath.
"No studio is 250 developers working on one game, that's just unheard of. This is a huge game."
Olin added that as well as a full multiplayer reveal on September 1, there will be "one more thing" to come, along with a co-op mode reveal before the game's release on November 9.
