The Assault strike package works the same as the Killstreak reward system in Modern Warfare 2 and Black Ops, the player must earn more and more points without dying. Once the player is killed, his or her points are reset to zero. Likewise, the Specialist strike package rewards players with perks after every second consecutive kill. Upon death, however, the player loses all the perks and the points are reset to zero. In contrast, the Support strike package is awarded based on the total points that the player has earned over the entire match, regardless of how often the player dies.
