Killstreaks have been redesigned to reward different play styles and skill levels through unique Strike Packages. Completing game mode objectives now counts towards your Pointstreak progression. For the first time ever, kills are not the only way to earn Pointstreaks.
Fan favorite game modes make their return (Free-for-All, Team Death, Match, Domination, etc.) and a series of new modes make their introduction to the Modern Warfare series
Kill Confirmed: Collect dog tags from killed players. Prevent the other team from collecting yours
Team Defender: Grab the flag and protect the flag carrier to increase your team's score
Infection: The infected kills enemies to recruit them for the infected team.
