Considering this game is stated to last 10 years, we will most likely be getting most if not all precision weapons found in prior Halo games so it only makes sense to think of ways to design them so they fit in the sandbox and are unique.
- Battle Rifle: not much to be said as it's the baseline 3 round burst weapon effective at medium range but capable in close and long if skilled enough. 2X zoom
- DMR: should be balanced so it does not receive RRR at close range, this would force it to be used at medium to long range where it should take 4-5 shots to kill with a slower fire rate than all other DMR's ( this way it won't be a death sentence for people running in the open but still very effective at range where it should be ) 5 or 6X zoom
- Magnum: assuming the magnum will come later it should probably follow the H2A and H4 model of being precise at close to medium range with low-medium damage and fire rate ( low damage high fire rate or medium damage but slow fire rate ) 2X zoom for slow fire rate magnum, no zoom or 1.25X zoom for rapid-fire magnum
- Carbine: in previous titles this weapon has largely been redundant thanks to being outclassed overall by other weapons, lets remedy this by giving the carbine the fastest TTK of all precision weapons but making the aim assist and bullet magnetism significantly lower than other weapons, rewarding skill and adding more options for combat ( and perhaps reducing it's RRR ) 1.5X zoom
- Lightrifle: Version A: H5 did a good job with this weapon as it had the fasted TTK, however for H:I it should probably find some other niche. So lets give it a slower TTK than the BR when unzoomed in but faster than the BR when zoomed, but making zoomed aim assist lower and unzoomed higher. Version B: Or a different approach to the lightrifle is making it slow firing 3-shot-kill weapon with low aim assist hip-fire and none when zoomed in ( or very little ) tell me which you prefer with version A or B. 3X zoom
- Boltshot: We'll follow the H4 version, turning this pistol into a medium firing hand cannon ( with short-medium RRR ) with an alt fire that burst-fires the weapon with high recoil ( and it won't insta-kill, maybe only drain shields ) and is limited by ammo consumption. No zoom
- Mangler: The demo showed this weapon as a medium-ish range revolver with high damage, perhaps it can be balanced to where it has very high headshot damage but low body shot damage. No Zoom
- Commando: Not sure how this weapon functions but we can probably assume it's a fast firing but low damage weapon requiring you to track your target for longer than other precision weapons but rewarded with quick headshots on unshielded targets. 2X zoom but could be reduced to 1.5X
