In an early mission (no spoilers from me!), I had just found what I am guessing is your first sniper rifle. Convieniently, a nice little pop-up told me "press this to open the loadout menu!". So I did. Slapped on a sniper rifle and off I went. It took all of 30 seconds to realise I also have a shotgun equipped. The only game I have ever actually enjoyed a shotgun in was Doom, and this ain't it. So I went back to the menus to take off the shotgun. One less weapon to scroll through, right?
Well, not so fast. I can't find the blasted menu anywhere! The only menu I would think to find it under is the "Squad" menu, and it only seems to have skill trees.
Where do I find the loadout menu? I was just in there. I doubt EA would have patched it out between the time I found the rifle and the time I wanted rid of the shotgun...
