A global stat site for Call of Duty: Black Ops 2 tracks the minutia of gameplay in real-time numbers, including the hours spent in-game, the number of scorestreaks called and even how many zombies have been killed by players and have killed players.
Viewers can watch the tally run up on grenades thrown, shots fired, kills, paybacks, assists, headshots, backstabs... There's all there, climbing faster than you can blink. You can also check out the number of cars destroyed, the amount of oil destroyed displayed in its worth in dollars, how many tons of C4 have been thrown and the number of crossbow bolts shot, along with a score of other features.
You can check out the ever-ticking counter here. Good work, soldiers.
