Scorestreak

The Scorestreak system is a multiplayer featured in Call of Duty: Online, replacing Killstreaks and Strike Chains. Scorestreak rewards are earned based on the amount of score one earns in a single life.

Players now earn rewards for earning a certain amount of score in a single life. This means actions like kills, captures, completing objectives, shooting down enemy air support, assists, and assists with certain scorestreaks count towards the earning of new scorestreak rewards. Like in previous Call of Duty games, the player's streak will reset upon death. Unlike Black Ops II, players can obtain more than one scorestreak with out using it. Streaks will only stack up twice, meaning a player can't have three Whisper Drones at one time.

For the first time in Call of Duty, players can upgrade their Scoresteaks.
