If I was to introduce this feature, the zoom function would zoom in or switch the modes of fire (or both) depending on the weapon. Now I know you have to be careful with this kind of thing because usually at best you’ll increase overlap and at worst make a weapon act like a completely different one based on the mode of fire. But I think there are some ways that 343 could do this that would “streamline” the weapons sandbox (although they might have to “merge” some weapons). Here’s some examples:
UNSC:
-Assault Rifle (SAW)
Give it a total of 48 rounds per clip.
1st mode of fire: Automatic (480 rpm)
2nd mode of fire: Automatic (720 rpm)
–In the low rate of fire there will be s very small reticle bloom (with less bloom per shot) and in the rapid fire mode there will be a much greater reticle bloom so it’s still an automatic weapon but between the modes of fire, you’re trading firepower and accuracy.
-Battle Rifle (DMR)
Give it 24 rounds
1st mode: 3 round burst
2nd mode: Semi (2x scope).
-Shotgun:
Give it 10 rounds
1st mode: pump
2nd mode: double tap.
–If you press the zoom button, you’ll pump the gun chambering a second round and when you pull the trigger, one round discharges and when you release it, a second round fires. If you want to double tap again after shooting one, you’ll have to press the zoom button again.
-Sniper rifle:
1st mode: Semi
2nd mode: Semi (10-5x zoom)
there’s no alternate mode of fire, you just zoom in.
-Rocket launcher:
1st mode: Semi
2nd mode: Lock (2x zoom)
–When you scope in, you have to lock on to a target to fire.
-Magnum:
1st mode: Semi
2nd mode: Silenced
–A silencer is placed on that allows you to shoot without alerting enemies but there’s a damage and accuracy cost.
-Spartan laser (Railgun)
1st mode: Quick charge
2nd mode: Power charge (2x zoom)
–When you’re scoped out the spartan laser will have the same charge and hold time as the railgun (but if you don’t fire by the end of the hold time it will “vent” so you don’t waste the shot) and use 5% of the battery per shot and when you zoom in, it will act like the spartan laser using 25% of the battery per shot. This would make sense because when the spartan laser shoots it fires 5 lasers in rapid succession so here it would fire them individually when you scope out.
Covenant Weapons:
-Plasma pistol
1st mode: Semi
2nd mode: Overcharged EMP
–Basically it would function the same as it does now but if you charge it up but your target moves out of site, if you press the zoom button, it will vent the gun so you don’t waste the shot
-Plasma rifle (Storm rifle)
1st mode: Automatic (high damage)
2nd mode: Automatic (high velocity)
–In the first mode of fire, the plasma bolts move as fast as the plasma rifles’ but when you switch to the 2nd, the bolts move as fast as the storm rifles’ but do less damage (and neither would have a reticle bloom which would make them more balanced with the hit-scan assault rifle).
-Needler:
1st mode: Seeker
2nd mode: High velocity
–In the second mode, the needles move faster but don’t track targets.
Fuel rod gun:
1st mode: Semi
2nd mode: Charged high velocity
–If you hold the trigger down to charge the shot, it will increase the velocity of the projectile and if you loose your target while charging, you can press the zoom button to vent the charge so the round isn’t discharged.
