PC version
Criticism has arisen of changes made to the PC version of Modern Warfare 2 including the lack of dedicated servers, latency issues of the listen server-only IWNET, lack of console commands, lack of support for matches larger than 18 players, and inability to vote towards kicking or banning cheating players immediately.[30] When asked about the removal of console menu commands, Infinity Ward responded with, "We would like you to play the game the way we designed and balanced it."
Defending their decision towards the lack of dedicated servers, Infinity Ward maintains that IWNET will "put you in the game that will give you the smoothest gameplay possible without you having to manually find a server with the best ping." In addition, it is stated that the utilization of Valve's Anti-Cheat system will eliminate the need to worry about "joining a server full of aim-bots, wallhacks, or cheaters. Or relying on the server administrator to constantly be monitoring, banning, and policing it."[31] However, Valve's anti-cheat system was designed to punish cheating, not to prevent it, by banning cheaters after a random delay.[32] Taking a different view, Ars Technica writer Ben Kuchera wrote, "At launch, this will be one of the most locked-down, inflexible, and gamer-unfriendly [games] ever created."[30]
An online petition was launched immediately after the announcement of the changes to the game's multiplayer aspect, urging Infinity Ward to reconsider its stance, with over 200,000 signatures.[33] When asked for a comment on the petition, Infinity Ward's Robert Bowling stated that it “definitely made a big wave, and the response will not be ignored. I’ll ensure everyone at IW sees the petitions and responds to it.”[34] The game went on to beat its predecessor's first week sales without yielding to any of the demands [35] but had dropped down to 39th place on the PC after three weeks, a decline not shared by the console versions.[36] Shortly after release a screenshot was circulated on the internet showing a number of members in one of the boycott groups on Steam playing Modern Warfare 2.[37][38] By May 2010, coders unlocked the developer console and managed to recreate the effect of dedicated servers.
