Well the Stinger is already in the game files, I think they are just trying to figure out when they can add that to the Pacific without everyone losing their shit over it. Personally I’m also hopeful that we see weapons that aren’t primary weapons feature as gold-order weapons, namely the Panzerfaust 150 and the Fliegerfaust.
There are also a number of grenade/AT handguns in the game files which I can’t see fitting into the normal progression.
now you just need a 20-foot Nephelium to carry it
