It was be a little easier and less annoying if square wasn't the button you use for everything. Like in zombies, when I'm trying to close a window and a reload instead. I have 1 bullet and 1 zombie walking towards me. Id like to use that ammo on him before I reload. Also in MW3 multiplayer when I go to reload and am walking over a weapon on the ground I end up picking that up instead of reloading my weapon. It may just be me on this, but it's annoying and I've been killed a few times because of it.
