Ok guys, lets all try to think of some new weapons for the new trilogy that don’t upset gameplay balance!
Explosive Crossbow:
Basically like a sticky grenade crossed with a sniper, aim, shoot, boom! 
1 ammo clip
EMP:
more like an assist weapon or a helpful weapon rather than a killer, aim at a vehicle and shoot, and it emps it and shuts it down a few seconds, or hit an enemy and it drops the shield. 1 ammo clip
Heavy machine gun:
like the normal AR but with 30% extra damage, and a much larger clip. would be a power weapon.
Machete:
Common! cos nobodies wanted to see the chief wielding a mechete when facing an army of flood or grunts.
Plasma Mine:
fire at a wall, wait for an unsespecting enemy to walk into it!
Hacker:
Fire at a weapon on the ground to make it jam and won’t work! or hit a weapon dead one in the enemy’s hands!
your turn people! lets come up with some really cool ideas!
Too simular to Call-Of-Duty.
I would like more original guns in a halo game.
LMG that has the same function as all LMGs and keeps the enemies head down

That is not halo haha,
I would like a human melee weapon, or to be able to use double energy sword, or that spear looking thing from the Halo Wars Concept art
EMP Trip Mine
Spartan Voltage Sword(made of forerunner alloy, enhanced by static auroa)
Gauss Rifle(like the DMR with scope, but shoots gauss projectile. Reticle is so small, scoping is pretty much required)
Gravity Grenade(blasts players and vehicles across the map)
GRAV NADE GRAV NADE GRAV NADE
woo!
A grenade launcher with a revolving chamber reloading system, allowing a few grenades to be shot in succession. I guess it’d be like the Brute Shot, now that I think about it.
Oh, and it’d be a UNSC weapon, of course.
Confetti Launcher:
A forge ecxclusive weapon, Charge up it fire harmless confetti at the enemy. Does zero damage, Fun to shoot, can be used as a flare gun
Brute bow
Looks like this
and shoots spiked arrows
-
Heavy Machine Gun.
Basically Jorges gun, only not acting like a turret…so it should be first person instead of third.
-
MA5K.
Shorter version of the MA5B AR, could replace the Silenced SMG. Light scoped automatic weapon with recoil.
Now for some more outlandish stuff.
Coming from someone who doesn’t believe ex-Covies will make a return in Halo 4, I’d still say this (in a scenario where they are included, or maybe just for multi).
-
Energy Cutlass
If Jackals make a return, give some of them this nasty little thing.
-
Impaler.
If Brutes make a return, give them some sort of mid-ranged “sniper”. Kind of like the DMR in terms of range, but make it semi-automatic and have it shoot single 30 cm long spikes that can impale people (nothing more “gruesome” than the Needler rounds being stuck into people…), with a bajonet on the top for close combat action.
-
Airstrike.
Forget about the MAC blast. The concept is nice and all, but a real MAC blast can never be shown properly during gameplay. Instead, remove the Target Locator with an extra set of grenades: flares (the Alan Wake style, red smokey flares). And then have a Longsword or similar aircraft performa a Carpet Bomb strike at that area.
