Can you get different secondary weapons in moh. besides the regular ones?
Nope, although there is a movement for having D/C gives us the option to pick our sidearms though. So far now, no. Maybe later on though.
If you really don't like BF4, get a refund and kindly never come back mkay. If you're whining about not getting a refund on the forums, contact EA support. If you're one of those dimwits who wants to sue EA, don't come to forums, contact their legal team mkay. Most of you won't, don't have the guts for it.
