The AN-94 assault rifle and the ISO submachine gun arrived in Modern Warfare on Wednesday in the launch of the game's fifth season. Both weapons can be unlocked without spending money by leveling up the season's battle pass.

The AN-94, which has appeared in eight Call of Duty games to date, is a 5.43x39mm, fully automatic Russian assault rifle. It can be unlocked by reaching level 31 in the battle pass, making it something of a grind to add the gun to your collection.
