First off, yeah go ahead and delete it Lorknis, I should have mentioned it here.
Second: count your shots. If you use up your weapons clip and forget to reload, well there's that rounds attack action out the window. For gameplay purposes I'm assuming your characters have as much ammo as needed on them, but you still have to reload the guns. Throwing the gun was actually an action I hadn't thought of so congrats for surprising me Perigrin.
You guys can move and shoot, and if you hadn't noticed cover deteriates the more it gets shot up. Also, you can pick up enemy weapons.
