Call of Duty: World at War is a bit of a popular thing. We've just received word that the game, launched in November of 2008, has now sold more than 11 million units - no small feat, well done!

Once they get the thank-yous and self-congratulations out the way, the guys at Treyarch are introducing a new feature to the game - the Dossier. Every shot, every death and every kill you make when playing the game is being tracked and stored - and now those stats are being organised and displayed, as easily accessible Dossier files that you're encouraged to check out!

So - how do you do this? Simply link your Call of Duty: World at War HQ account to the gamer ID you use to play (this is easily accessible through the Linking tab when you edit your profile). Once you're done, you can view Dossiers by clicking the CoD: WaW Dossier tab inside the "User Profiles" tab on the CoD: WaW HQ website - and there's a veritable treasure trove of information just waiting for you.

The devs explain that there are "far too many" stats and data provided for them to be able to cover everything in this story, so instead, they're focussing on the Killshots Heatmap, Killshot Bodymap, Weapon Usage and Compare Stats.

Killshot Heatmap The Killshot Heatmap can be viewed in Match Details and provides intel on the most frequent locations of where you and others have been killed on the map. Why is this important? This map gives you the locations of so called “hot-spots” on the battlefield, letting you know where others will be and most likely where you shouldn’t. When approaching “hot-spots,” it’s a good idea to stay on the outside perimeters; therefore you can be the one picking off enemy soldiers traveling through the more treacherous pathways.

Killshot Bodymap Like the Killshot Heatmap, the Killshot Bodymap shows “hot-spots,” but these “hot-spots” are of a completely different nature. The Killshot Bodymap shows you where your bullets are landing on the enemy and can help you fine-tune your accuracy. If your Killshot Bodymap’s legs are lit up like the Vegas strip, than it may be time to practice your aiming. A great Killshot Bodymap should have a red emblazoned chest with a slightly rosy head. However, the ideal Bodymap may change depending on the weapon. With a sniper rifle you’ll want to see more concentration on the head where as with an MG, leg and arm shots are not great, but more acceptable.

Weapon Usage Stats on Weapon Usage can be vital to improving your game. You might think that you are wildly inaccurate with the Thompson or MP40, but when you see a high kill count next to the gun, you might not care anymore. Studying Weapon Usage can expose both your skills and weaknesses with certain guns. Take the time to identify what guns you are struggling with and work to improve those skills. The most lethal type of soldier is always the one that can utilize a varied arsenal.

Compare Stats Lastly, all soldiers should check out the Compare Stats section and visit the profiles of other players as well. Stats mean nothing if you can’t brag about them and with Compare Stats you can see your statistics side-by-side your friend’s to prove which soldier is the top gunner.

After that whirlwind tour of the Dossier feature - rest assured that there's plenty more tucked away there. The fellas at Treyarch recommend that all soldiers link up their profiles and "dive head first" into this feature - there's something in it for all Call of Duty: World at War fans, whether you're the sort who loves stats or not.
