Hi just a suggestion I felt like making is you should add an option under the explosives tabs to get more under-barrel launcher ammo. Especially in co-op because when i play as security I don't find myself wanting to use a shoulder launcher as much as I would on the insurgent side, for the helicopters mostly. Extra ammo would be nice for more building and corner clearing where a shoulder launcher is quite a bit slower to handle and a bit overkill in my opinion. Or you could go back to a system similar to the first games where you have to chose under-barrel or shoulder launcher and using the ammo upgrade gives you more grenades.
