Often times in Crysis 2 multiplayer I find myself fumbling through my weaponry. During a long kill streak I tend to have forgotten if I have already used my Frag/C4 and get caught checking ammo on my primary, secondary, and try switching to my explosive only to find that there is nothing there anymore. It would be helpful if there was some indicator near the ammo count on the HUD that displayed if I have already used my equipment or not.

Just a thought on improving the game in subtle ways.
