According to the current statistics found at the Killzone: Mercenary website, a total of 47,005,620 lives have already been terminated. The total accuracy of the players is 31% while in all of these kills, 11,403,914 of them died via headshot. Ouch. Melee Kills, on the other hand, amounts to 5,976,925. The weapon with the most number of kills? The M82.
That is some stats worth bragging, especially for a handheld game. Killzone: Mercenary has been out in North America for at least a week now.
