Specialist Package - Killstreaks
The Specialist Package Strike Chain is a bit different. You don't get to select regular killstreaks. Instead, you get to select 3 extra perks. These perks will be unlocked after 2, 4 and 6 kills. If you reach 8 kills without dying, you will be given every single perk in MW3. If you die, it resets back to the default. Choosing the Specialist Package means that you won't get to avail of other killstreaks.
