Pop quiz: how many Call of Duty games have there been? With the all-over-the-place naming convention it's hard to figure out - four WW2 games, three Modern Warfares, three Black Ops (so far) a World at War, and a few futuristic one-offs in a pear tree. The good news is that IGN has been reviewing them since way back in 2003 when the first duty called, so below you can scroll through a gallery of the contemporaneous score and Verdict on every game in the series.
But before you do, a challenge:
1) How many Call of Duty games have received a 10 from IGN?
2) What's the highest-scoring Call of Duty game?
3) What's the lowest-scoring Call of Duty game?
