Let’s compare all returning guns throughout entire Modern Warfare series. That is Call of Duty 4 Modern Warfare , Call of Duty Modern Warfare 2, CoD Modern Warfare 3, Modern Warfare Remastered and of course upcoming Modern Warfare 2019.
There are only 4 weapons that are present in all games:
M14 (in MW2 there’s only silenced version available)
MP5 (please note that in CoD MW2 there’s only MP5K availabe).
What do you think, which one looks and sounds the best?
