AS the release date for the next Call of Duty game draws ever closer, we are seeing more details of some of the games features. The latest feature we can tell you about is the “Combat Record”. You could be seeing what types of guns are mostly used, and which ones have the highest kill ratio, and much more.
Normally with every new Call of Duty game has stuck mainly to the same formula with only the odd small new feature added to each game. But this time with Call of Duty: Black Ops this has completely changed with all the new features being announced.
Combat Record will be seen for the first time in the new game, and will detail everything you have done so far in a variety of lovely graphs for you to view. There could also be the capability for other people to look at certain stats from your progress as well.
