Hi everyone thanks for reading this article and I hope you enjoy it 
- Silenced Sniper. [UNSC]
The silenced Sniper is a lot like the regular sniper rifle but it will not leave a big smokes trail behind it. It has five shots and fire a tiny bit faster than the original sniper Rifle. However with the up sides comes the downsides. The silenced sniper is reasonably hard to aim and in terms of damage it takes two shots to the head to kill and three to the body. - Blast grenades. [Forerunner]
Blast grenades are not very powerful however have one cool feature that might get players interested. It has a lot of force, about the same as two concussion rifle shots combine sending vehicles in major spinning confusion. - Smoke grenades [UNSC/Covenant]
(Self explanatory)
4.Zealot blades. [Covenant]
Zealot blades are a forced duel wield weapon that is also used for stealthy engagements. It takes two hits to kill and has a slightly faster slice rate than the energy sword. However when faced against a guy with the energy sword the guy with the energy sword will most likely win due to lunge and two special effects. 1. It drains the ammo at double it rate when clashing with Zealot blades 2. The force of the sword against blades will send you opponent flying backward leaving him stunned of falling to his death. - Disintegrator [Forerunner]
This Forerunner heavy weapon is like the focus rifle from halo reach but with a twist. The longer it is firing for, the more damage it can deal out and when it drops below 25% of charge it goes into overdrive making twice fast to hit the max damage. It can overheat and the ammo in it runs out quite quickly. A little bit like the saw. - Stalker [Brutes]
The Stalker (inspired by the spiker) is the main assault rifle of the brutes. It has a slower rate of fire than the assault rifle but can hold up to a good amount of ammo (btw I have my own drawings and concepts of this weapon and it looks beast!) - Fusion rifle (Forerunner)
The fusion is like the Spartan laser but with a twist. Its lasers fuse together! The gun has five lasers. The middle one in phase one does no damage and Top left, Top right, Bottom left and Bottom right do a minor amount of damage. In phase two the gun has two options. 1. Fires three lasers in a row. 2. If the power is kept in for too long it turn into a massive pulse grenade of death killing almost everything (Does a lot of damage) so it must be fired. The pulse grenade explosion takes about 7.5 seconds to detonate and the person can be used as a kamikaze to wipe out a massive enemy force or block a big passageway. It can only be used three times and the 1st attack takes 5s to charge up.
If you want more let me know I have a bunch of other ideas
