The yearly releases of the Call of Duty series are a big event for the world of gaming and one of the biggest draws is the multiplayer mode, which is quickly becoming one of the most popular for those playing both on home console and on the PC.

And it seems that as the popularity of the series has grown as the developers, be they Treyarch or Infinity Ward, have been spending more and more time trying to make sure that there's no way for cheaters to get unfair advantages in the multiplayer matches.

Dan Bunting, who is the leader of the team working on the multiplayer side of Black Ops, has told Gamasutra as part of a new interview that, “There was kind of that turning point during life-cycle, and, coming away from that, we realized that it had to be a big agenda for us to develop the tools and infrastructure within the game to make sure that we could track and keep the online experience clean,” talking about the experience the team had with previous Call of Duty game World at War.

He added, “We've had about probably twelve to sixteenth months of development time spent on our security tools and infrastructure; it's very robust, and it's been incredibly successful in this game.”

Infinity Ward, who are currently working on Call of Duty: Modern Warfare 3, are probably spending just as much time if not more working on anti-cheat measures for their game.

Bunting has also talked about the maps that the team has created for downloadable content saying that the way certain game environments become popular has surprised the team, with players often becoming more interested in the smaller maps for Black Ops, despite the chaotic nature of playing on them.

Call of Duty: Modern Warfare 3 has been predicted to sell more than 20 million copies.
