It was inevitable Activision wouldn't sit on the Call of Duty franchise, especially after the huge success that was, and remains to be, Call of Duty 4. Recently reports of Call of Duty 5 being in the works and going back to the series' WWII roots began to surface with further speculation Infinity Ward would not be involved in the project.

These reports and speculation have all but been officially confirmed by Activision themselves. The series is indeed heading back to WWII, this time focusing more on the Pacific end of the campaign. Call of Duty 5: World at War will be developed by Treyarch, who were responsible for COD3, and will utilise the same engine used for COD4 with a host of new features and gameplay innovations.

According to reports, players will have the ability to burn buildings and set grass on fire in this iteration, while a new Flamethrower weapon will also be introduced. For the most part, you'll play as the US fighting the Japanese, however, it has also been revealed you'll play campaigns as the Russians invading Germany. Another new feature for the single-player mode will see you having the ability to finally command your troops in the field, while multiplayer will borrow heavily from the COD4 blue-print with Perks derived from WWII-centric abilities and uses.

The reports go on to say the lead build of the game is the Xbox 360 platform, however, it is being developed for PS3 and PC as well. Rumour also has it Infinity Ward are now working on COD6 which will continue its focus on Modern Warfare (though this is just a rumour for the time-being).

We contacted Actvision Australia for anything absolutely official, but were unable to get any comment from them. As soon as we see anything in the way of screens, press releases or videos though, you'll be the first to know.
