Treyarch always did go one better than “other Call of Duty developers” when it came to multiplayer stats and leaderboards. With Black Ops they are taking it to the next level, calling what they have done “our most aggressive leaderboard effort to date”. That means we can expect all of the goodness that World at War gave us in the stats department (heatmaps FTW), along with a slew of new stuff including the way stats are sorted.
Recently in a post on the CoD forums, Treyarch’s David Vonderhaar revealed a brand-new system for the leaderboards; they will be sorted on a score-per-minute average basis. This, amongst other things, will mean that people who play objective modes and actually capture objectives will be rewarded.
