Scorestreak

Scorestreaks is a new multiplayer rewards system introduced in Call of Duty: Black Ops II, replacing Killstreaks and Strike Chains. In this system, rewards are earned based on the amount of score one earns in a single life.

Overview
In previous Call of Duty games, players were allowed to bring up to 3 rewards with them to be earned after earning a certain amount of kills or earning a certain number of points. However, players now earn rewards for earning a certain amount of score in a single life. This means actions like kills, captures, flag grabbing, assists, and assists with certain scorestreaks count towards the earning of new scorestreaks. However, the streak ends upon death and streaks cannot be repeated in the same life.
