The entire complement of the Modern Warfare II weaponry will receive a weapon balancing pass by Sledgehammer Games, with additional adjustments after launch, as needed.
These aspects of MWII weapons may be changed as part of this balancing pass:
Damage ranges
Damage values
Damage location multipliers (head, torso, legs)
Attachment value magnitudes (e.g., reducing MWII laser ADS speeds)
Attachment PROS and CONS values
This weapon balancing pass will ensure weapons from Modern Warfare II are optimized to perform alongside the new Modern Warfare III weapons arsenal, while maintaining the identity of the MWII weapons as much as possible. The team will be observing weapons performance at launch and beyond as part of ongoing post-launch game refinements.
