How the hell a barrel charger works?
(It's a bigger barrel, when gunpower is enough, what actually augments bullet speed and damage. Since gunpowder deflagration energy is better focused on that projectile instead of dispersed after exiting a shorter barrel.)
Why an extended barrel reduce damage when improving accuracy?
(No way... As described above.)
What the shotgun stock have to do with buckshot not performing normally?
Why do a marine corps distribute pistol grip shotguns without even a foldable stock?
(Nah, the shotgun by the movie wasn't regular issue. It was a personal weapon of a specific character.
Of course many games copied this, but it's still nonsense.)
Why can't a "piccatiny rail or analogue" based attachment fit one gun, but not another?
(Yeah, I am all for dumb and stupid configurations many newbies would create like attaching red dots to flamethrowers, or silly stuff as having a shotgun with an underbarrel shotgun. Still I do thinf attachments should have a logical explanation for not fitting where size would be a factor.
But if a marine think placing a sniper rifle sized scope on a pistol is a good idea, let him do it.
Let him have the scope crash into his eye or something when firing.)
What the heck is a quickfire that fits on the upper rail? Or a burstfire fitting on the lower rail?
(Make those "firing mechanism replacements" or something on that line. There is no way something externally attached to a gun would change the way it fires. Even some "autofire gadgets" that do exist work over the trigger block.)
Why the muffler or silencer need to reduce damage? Why it work with regular ammo?
(No, it's not this way it work. This component can't "totally silence" a regular supersonic speed cartridge.
It will still be noisy. Causing the usual "cracking" into the air as the gun fires.
But it can silence a subsonic cartridge that haves less gunpowder on it and THIS specific type of ammo deals less damage.
Indeed, on this game, guns being silent IS a disvantage on most circumstances.)
And barrel attachments have specific calibers.
(You can't take out the silencer in your pistol and put it on a rifle of a different caliber.
I know it's "coding hell" to make all this stuff but...)
But marines need hard hitting weapon mods and....
- Give them some "+p+ ammo" that have more gunpowder, cause more damage and deals more recoil. Being totally unreliable if autofiring.
Rarelly hitting any round after the first one. But let them learn it by themselves.
- Also "explosive rounds" that deal a 1x1 explosion damage (only hitting the target), where effectiveness depends on it penetrating or not the armor, like the actual rifle explosive rounds from WW2. (Let them explode themselves on FF.)
- And why not some "training ammo", low damage rounds to be dispensed on firing range? (They seriously should have a decent training facility aboard. Particularly good for the newbies.)
That said, a bigger and heavyer gun IS a disvantage by itself.
Carrying one makes you slower.
Bigger barrel should cause drawing delays unless it's on your back.
Larger gun should'nt fit into an armor scabbard.
