Modern Warfare dev responds to Field Upgrade Pro issues
Infinity Ward’s multiplayer director Joe Cecot has responded to a glitch where Field Upgrade Pro would fail to work correctly for Modern Warfare players.
Field Upgrades are one of the new Call of Duty features that were introduced in Modern Warfare and they provide players with cooldown-based bonuses such as Dead Silence or a Munitions Box.
While players can only choose one per game initially, after reaching a certain rank you will be able to unlock Field Upgrade Pro, which allows you to equip two bonuses at once.
