Trivia[]

General[]

Call of Duty: Modern Warfare III[]

  • If the player uses any .300 Blackout ammunition exclusive to Modern Warfare III, such as High Grain or Low Grain, the stat changes brought by Modern Warfare II .300 Blackout ammo types will not apply, like increased damage and recoil for example, and will be functionally identical to the 5.56 counterparts.
  • The ISO Hemlock's Pack-a-Punch name, So Crates, is a reference to the Greek philosopher Socrates.
