Underbarrel attachments


Lately I’ve been reviewing over a good amount of peoples forums explaining or numerous need detail additions for the game say a storage system and inventory management. What drove my attention on this was that alot of people carried the rocket launcher around due to the off and on chance of fight big bad tanks and such. Why not add the underbarrel grenade launcher in game to support that quick explosive need to all without wasting time switching over weapons. Obviously its only compatable to assault rifles but why not have it where its handheld like the binoculars and have it stored in the quick slot as well?
