Plutonium

Advanced Warfare has already been made in the S1X Client https://xlabs.dev/support_s1x_client but Infinite Warfare hasnt been made as far as i know, but S1X also has MW2 and Ghosts.

Dss0 This question seems to be a unsolved problem.😁
Btw It is right what you said sir.

Darkshadow39 It is possibility that you haven't downloaded the weapon files.
repair your files through steam, if you have downloaded from torrent go to install DLC section. It can help

at bottom left corner of your screen right click your windows icon and select Run then type : %localappdata%

then go to plutonium folder then storage then t6 then images (if you dont have images create one) then put your .iwi files in images folder 😁
