On November 16, 2022, Season 1 of Call of Duty Modern Warfare 2 and Warzone 2 officially began. There are many new features landed within the last chapter of the series Activisionincluding new weapons and the equivalent of Veteran mode in Call of Duty Modern Warfare 2.
Among the new guns added with Season 1, we pay particular attention to the M13B assault rifle. According to currently available information, however, there appears to be no way to unlock this weapon in COD Modern Warfare 2: it will be possible to obtain it within Call of Duty Warzone 2. To do this you will need to play a game in DMZ modedefeat the Chemist Boss inside the Radioactive Zone and complete the extraction using the weapon he will drop on the ground.
Despite this, it is possible that at the end of Season 1 the M13B rifle will be made available also within the last episode of the signed series Infinity Wardperhaps through one of the many weapon missions that we have now come to know, a scheme for the release of weapons already used in the past by Activision in previous games in the series that interfaced with Warzone.
