As I have only played Modern Warfare 2 on the PC I can only answer for that. Modern Warfare 2 does not have the option to have dedicated servers. This means that in each online game one of the players is automatically selected to be the server. This makes it impossible for a map other than one of the original ones to be hosted on a server.
No
I highly doubt it considering the next Call of Duty will be the 7th. The creators will run out of wars to make unless they made more of there own like Modern Warfare and Modern Warfare 2.
yes i'can
No they will not. Activision will own it and I believe they also own Infinity Ward. When we say Call of Duty Modern Warfare is done by Infinity Ward that does not mean that they make all the games versions. Others companies also help develop the games like the Call of Duty Reflex Edition developed by Treyarch or the Call of Duty Modern Warfare Mobilized which was also not developed by Infinity Ward and was created for Activision as is the complete Call of Duty series of games
You have to get to level 4.
No, you can not make your own Nazi zombies map. you can tyring to find the sight now
Once you hit level 5, you can make your own classes in the lobby before you start a game.
You need to either join someone who is hosting a hacked lobby, or you buy a program to hack your xbox and host your own.
only if u own at modern warfare 2
This is completely subjective and a matter of opinion, however my opinion would be that they're both good quality games. They both have their own advantages, modern warfare 2 has much better perks and more personalisation, however modern warfare 1 has better maps and better guns, overall i'd say only you can answer the question, but my experience would say COD 4
go to private match.
Modern Warfare 3 is so popular because it appeals to a young generation with its violence. For example, if a 13 year old had a bad day, he could take it out on the delta force with a M 14. Plus Modern Warfare 3 is a highly commercialized video game. It even has its own web sight. Overall Modern Warfare 3 is appealing because of online playing mode and new survival mode.
HELL YEAH haha i answered my own question No because i am not buying it (i think)
