Most of the Call of Duty games are set in World War 2, the only games to break this trend are Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2, which are (as evident by their names) set in modern times. (Note: I do not, and never have played Call of Duty, all information is based off of simple internet research, try it next time.)
All of these games can be found in gaming shops like EB-Games, JB HIFI or you could buy the games over the internet from ebay. If you wanted to try the games i suggest you rent them from your local video shop.
None of the Call Of Duty games has auto aim i guess!
Yes there are call of duty games that have co-op.
