Infinity Ward is bringing back the MW3 feature of Strike Packages for the killstreak system in Call of Duty: Ghosts MP.
Mark Rubin went up on stage and talked all about the packages, including the fact that you earn points for taking down enemy streaks, destroying objectives, capturing objectives, and kills.
For the Assault package, they’ve made more killstreaks on the ground – not all in the air anymore. UAV is now called Sat Com and is placed in the map.
For the Support package, they’ve made the streaks more support based – not driven by assault.
For Specialist, it’s the same as MW3, Unlock perks as you get more kills.
