How do people shoot so fast in call of duty world at war Xbox 360 and do people who play call of duty on the wii and PS3 still play on the network with people who play CoD on the Xbox?

Answer 1

People use an automatic controller which enables you to shoot fast. I recomend not using one because they can report you and if you get 25 reports for the same thing you're account will be suspended for a few days to a week or two. Whoever said that you will be restarted to level 1 obviously has no knowledge of the game, what-so-ever.

and no, the will and ps3 are different than the Xbox 360 servers. because the xbox competes with these systems. not work together. and the wii version is different from the others from main menu instead of a person with his weapon the wii verson shows selected pictures from the game.

Your Xbox 360 game is different from the other versions of the game will not work in there platforms and can not play them because the games are not compatible. Yes it is true they all use different networks, but there incompatibility goes way beyond just online access capability

Some people can shoot faster and may not be using an automatic controller. I don't know about Xbox live, but cheating has much harsher penalties on the PSN and doubt that Xbox 360 allows 25 warnings with only a short suspension.
