"Call of Duty: Advanced Warfare"  launches on Nov. 4 for Xbox 360, Xbox One, Playstation 3 and 4, and PC. Insiders say those interested to get an early copy, one day early, can do so through the Day Zero Edition. 

Conan's review of Advanced Warfare will come out next week. To tease his audience, both on TV and online, he made this video showing not the game screen, but how he reacts to the excitement.

Suffice it to say, he's excited about it. That last part, he even goes as far to say, "that was the greatest feeling I've ever experienced, and I've watched two of my children be born."

According to othes sources, fans have found out so far that the campaign can be accomplished in around five hours. Also, the playable modes coming at launch have been revealed to include Hardcore TDM, Hardcore Domination, Hardcore Kill Confirmed and Hardcore Search and Destroy. 

"Call of Duty: Advanced Warfare" will have two popular modes: the Infected and the Gun Gameas Newsweek reports. The two additional game modes are part of the announced 13 game modes that will be available when the title is launched.

Gun Game will see players having the same pistol at the start of the mode. Each kill for Gun Game earns the player a weapons upgrade automatically. The way to win is to go through the entire arsenal round, something that game observers say could be difficult since your weapon is downgraded every time you die.
