SMGs have had a solid place in the lineup of guns in bothCall of Duty: Modern WarfareandWarzone. TheMP5 is often regarded as the best SMG inCall of Duty. Even after multiple nerfs to the gun, it has remained a solid option. However, fans are frustrated, as it seems like a secret change was implemented to the gun recently.

The odd part about the possible change is that players are reporting various differences from one another. Some are saying that the MP5’s iron sights are different, with the gun being far more zoomed in. The sights are part of the reason thebest MP5 loadoutscan go without an optical, so a sudden change without warning would be a problem.

Others indicate that the sight of the MP5 hasn’t been changed at all, and tweets and Reddit posts online paint the story that either idea could be true, only adding to the mystery. Others are reporting that the recoil has been altered. With players routinely looking forzero loadout options forWarzoneandMW, it can be infuriating when a favorite fun has a change to the feel of the recoil.

Players like scparz, a professionalCODplayer, are among the group of players that are reporting the MP5 is “bouncing all over the place,” which has certainly not historically been the case for the SMG. The MP5 has always had some of the most consistent recoil inModern Warfare, but perhaps not anymore.

The thing that really is upsetting the community is that this secret change looks to have been implemented at the worst possible time. TheCall of DutyLeague Championship Weekend is right around the corner, and it may be that the developers seriously altered one of the most used guns without proper communication only days before the event.

It is possible that the changes are due to an untimely glitch.Modern WarfareandWarzonehave been plagued by bugs, with the most recentMWglitch giving extra perks to players. If it is a glitch, and nothing else, one would hope that it is patched before any multi-million dollar tournament.

New content is consistently dropping for Season 5 andMW/Warzone. The major concerns from fans are that the developers haven’t communicated a possible change, that the gun is a favorite and altering it would be disappointing to many.
