@depleted I realize that the HUD fades away after a couple of seconds, and I know I can check the HUD's Ammo count just by doing quick swap using the scroll wheel on my end. It's that easy to check the HUD. Even I honestly gained a habit of quickly checking the ammo count before pushing up.
Yes, I know there are weapons where you have to load one round each with shotguns and bolt-action rifles which the HUD includes how many rounds you have, but that doesn't include the automatic & semiatuo weapons which are more effective than shotguns and bolt-action. Also you're wrong, you only see how much ammo you have in reserve, but not literally in the weapon's magazine itself which is what INS:S is now showing. For example, I load the TOZ with 7 rounds with 36 shells left, I fire off some shells, but I lost track. The HUD will still say I have 36 shells, but not tell me how many rounds are in the shotgun itself, so now I either keep going or I reload just to be safe. Same for the rest of the magazine-fed weapons, but the HUD only tells you how many magazines you have and not how many bullets are in the magazine loaded into the gun. I believe having the same ability with rifles, SMG, LMG, and battle rifles would make gunplay unnecessarily easier for all weapons now when keeping track when to reload.
Well good for you you're a veteran player of the original mod (assuming onto INS, DOI, and the beta), but I'm also an advit player on the official game INS & DOI spending almost 700 hrs in total so I'm not a newblood to NWI's work. Because of their games, I moved on to RS2 and Squad. About Squad, I know that they use a similar HUD system, but as an Insurgency fan who have enjoyed learning how to play well in their games with their mechanics, gameplay elements, and strategy, I felt it's a small, but critical difference toward the casual side in their slightly-new styled gamplay. The title says "suggestion", not "have to do it, or I'm refunding the game", so I'm just giving an idea like everyone else on this forum for the developers to consider. If you think my suggestion is so ridiculous for a veteran like you, then look for another post that was criticizing the addition of female characters or how someone claimed that the M249 LMG's recoil is too uncontrollable.
I do look like I'm hellbent on NWI to change the HUD, and I do because I believe I have a thoughtful suggestion, but if they don't want to change the HUD ultimately, fine. I still love the game based off my ALPHA and currently BETA experience, and I'm happy owning this game that supports an indie studio doing something AAA FPS games don't do. Besides, we both don't know for sure that if other INS mod veterans have the same idea like yours. Maybe they'll see the addition of a mag count from INS is a crutch, and see INS:S as NWI's take towards COD, and that's ridiculous to me.
I'll be honest that I didn't know there was a way to turn off the HUD through steam commands so I thought NWI would add an option in the settings to turn on, off, or modify elements of the HUD including fade time, size, and opacity. Could be in a later update if they want to. The developers, if they consider this opinion, would interpret this post to add options to modify the HUD, and that's fine with me.
