The way the Halo sandbox has almost always worked is that the UNSC and Covenant have always had a counterpart of eachother’s weapons. Now the weapon sandbox has been mixed up a bit. Since the game is more focused on a selection of your own weapon, it’d only make sense for the game to have more variety anyway.
UNSC - Covenant
BR - Carbine
DMR - ((Possibly Needle Rifle?))
AR - Storm Rifle
Sticky Detonator - ((Possibly altered plasma launcher type weapon?))
SAW - ((Concussion Rifle? Could it in fact be the Needler?))
Snipe - Beam Rifle
Rocket Launcher - Fuel Rod Cannon
Magnum - Plasma Pistol
Spartan Laser - ((Plasma Launcher?))
Rail Gun - ((???))
Shotgun - Sword
That’s 5 weapons the UNSC has that the Covenant doesn’t!
Although that’s not even factoring in the Promethean weapons.
From what we know the Prometheans have a boltshot which the pistol counterpart, the light rifle which could be the DMR/BR/Carbine counterpart, the surpressor which could easily be the AR/SR counterpart, the promethan sniper which is obvious, the scattershot which the shotgun/sword counterpart, and another unknown weapon we have yet to see confirmed what it can do, if we factor those in…
UNSC - Covenant - Prometheans
BR - Carbine - Light Rifle
DMR
AR - Storm Rifle - Surpressor
Sticky Detonator
SAW
Snipe - Beam Rifle - Promethean Sniper
Rocket Launcher - Fuel Rod Cannon
Magnum - Plasma Pistol - Boltshot
Spartan Laser
Rail Gun
Shotgun - Sword - Scattershot
Do you see the gaps here!? The UNSC seems to be having all the weapons but their faction counterparts don’t seem to have any. I sure hope there are plenty of weapons we have yet to see.
