MW4 Calling Cards Boost: The Cards That Show What You Have Done

A calling card is the first thing other players see when you top the scoreboard or take them out, and in Modern Warfare 4 the good ones are earned, not bought. They come from challenges spread across the whole game: Prestige challenges like Double-Tap, Elite objectives in Multiplayer, extraction tasks in DMZ, Campaign playthroughs and Shared Mode challenges that span several modes at once. Many run in tiers, so a single card can mean four rounds of the same task at rising difficulty, and finishing every challenge in a set rewards an animated Mastery Calling Card. Most players collect a few along the way and leave the rest locked.

KingBoost completes the challenges behind the cards you choose. Combine as many as you like in one order, from Prestige 1 to 4, Multiplayer, DMZ, Campaign or Shared Mode, and every tiered selection is finished through Tier 4, with the cards from the earlier tiers unlocking along the way.

YOU WILL GET

  • Your chosen Calling Cards from Prestige 1-4, Multiplayer, DMZ, Campaign and Shared Mode challenges
  • Tier 4 completion for tiered options, including the cards from all preceding tiers
  • An animated Mastery Calling Card if your order completes the last unfinished challenges in its Mastery Set
  • Weapon and account XP earned during the boost
REQUIREMENTS
Chevron
  • Access to the modes required for your selected challenges
  • Selected challenges unlocked and tracking progress, including any required Prestige challenges

Way smoother than the competition

I'm a busy guy and love to do M+ myself but can't sit around for raids too long. I've used other sites before where they promise a 15-min start window, but once you've paid they consistently tell you the starting time is hours away. They treat you like a number once the money is in. I've had a few runs with these guys now and every time it's not only fast but also smooth and friendly communication every single time. Wholly recommend these guys instead.. unless they start acting like that too, I'm not going back to the other sites.
