Hey, so there is an official blog post on this website it gives a tiny bit more details on things and within there, it states "up to 4 attachments" but I assume within those 4 categories you will have a good variety of attachments to choose from. I did initially have that reaction of , wow only 4, does not seem soo great, but after I thought about it like, well there could be like 5 or so options within each which for me is probably enough, some games there is just too much, but that's just me, but it for sure says up to 4 attachments and who knows things could still change as they want them too, without getting to try it out no one knows how it all feels. My other thing was they did not mention anything about melee weapons, unless I missed it, but I don't think it was mentioned.
