Old weapons

343 what about the old weapons like from ODST you the flamethrower and flame grenades?
Would be awesome catching enemy Spartans on fire …

We’ve been given the H2/3 BR, HCE Magnum and the SPNKR rocket launcher.
So I wouldn’t mind from:
Halo CE
MA5B, 60 round AR with ridiculous fire rate, if it was to have damage equivalent to H5s AR then it should have insane reticle bloom, and the lore states that it was prone to jamming so if that could be implemented in some form (every 25-140 rounds? randomly occurs within that limit)
M90 Shotgun, Featured in H2+3 as well, it’ll probably be just aesthetically different to H5s
Plasma Rifle, we know it’ll be coming back because of the Warzone Firefight trailer which showed the brute variant (if you don’t know about it then where have you been??) hoping it has the stun ability or something.
HCE needler, it did the most damage with individual needles than any other halo needler (when a needle shatters it deals decent damage)

Halo 2

M7/Caseless SMG
M6C magnum, give it reduced damage but higher fire rate
Halo 2/3 fuel rod, aeshetically different, higher fire rate, bullet drop
Brute shot
Brute plasma rifle, (again already been shown)
Sentinel beam

Halo 3/ODST
M6G magnum, it could kill in the same way the CE magnum could but with 4 shots instead of 3 and had a much slower fire rate and low accuracy
Missile pod, fired one rocket at a time, locked onto any vehicle
Plasma cannon, to me it seemed like it was more accurate than H5s when carrying it around.
Spiker, have increased melee damage like it did in this game.
Mauler, increase its range and max spare ammo, have it so it kills in one hit when at point blank range
Spike grenade and firebomb grenade
M6C/Silenced
M7 Silenced

Halo Reach
M392 DMR, will only aesthetically different to H5s
MA37 AR, aesthetically different
M45 shotgun, aesthetically different
Grenade launcher, personally I loved it
Needle rifle, blood of suban just isn’t the same, keep its fire rate and damage, reload speed etc. May need to reduce the number of needles to break the shield
Reach needler, H5s needler doesn’t have the climb in fire rate like almost all the others do (I think H2s needler is the only other that doesn’t) has the highest rate of fire of all needlers, among the best at homing and needs the shield down to supercombine, could put it in the same league as the SMG if balanced properly.
Plasma repeater, I prefer it over the storm rifle, plus you can vent it manually.
Concussion rifle, prefer this over the caster
Focus rifle, it wouldn’t need to be modified much because in the right hands its pretty lethal

Halo 4
Sticky det

sticky detonater
