Modern Warfare 3 day 1 patch fixes crashes and makes significant weapon balance changes

Call of Duty Modern Warfare 3 has exited the early access period for the campaign and officially launched today (November 10). However, players diving in should make sure they also download this essential day one patch.

Outlined on the Duty blog, the patch offers fixes and changes to the campaign, multiplayer UI, weapons, maps and more. Loading crashes in campaign missions have been fixed, as well as “UI-related crashes” when using the menus. Most notably, changes have been made to 13 weapons and two conversion kits, so if you found a favorite during the beta period you’ll definitely want to check that your weapon of choice still works as you remember it.
