343 Industries has added several things to the Halo series since taking over the reins from Bungie. One of the biggest things they've done is include the Prometheans as a villainous force. These strange creatures are an elite type of Forerunner warriors who debuted in Halo 4, then continued their destruction in the next game.
While they spend most of their time trying to kill you, they're not all bad. After all, by looting their corpses, you can get your hands on some unique pieces of weaponry. From long-range rifles to close-quarter firearms, these villains brought a full arsenal into the series. But which of them is the best? Note: non-usable ones or variants of other guns aren't included here.
9/9 Pulse Grenade, Weak Double Explosion
It's no surprise that the Pulse Grenades only appeared in one game, because they're not very effective. They explode into a giant sphere and, after a few seconds, detonate again.
If you catch people with it, it can do damage, but it's very easy to telegraph. This is because the glow it gives off is highly visible. While this isn't a problem for the first discharge, that alone isn't usually enough to kill people. These things are truly among the worst Halo weapons ever.
8/9 Splinter Turret, High Damage Yet Low Mobility
Ripping off turrets to use as handheld guns has been a staple of Halo for some time. And in Halo 5, the Prometheans provide you with a new turret to ruin. This one stands out because it fires projectiles that explode into smaller projectiles.
Unfortunately, though, it has the same weakness that similar weapons do: it lacks mobility. Walking around with the beast severely slows you down and leaves you wide open for enemy attacks. Still, at least it dishes out a lot of damage.
7/9 Suppressor, Excellent Fire Rate But Not Much Else
No one can deny that the Suppressor has an excellent fire rate. It even shoots faster than the UNSC Assault Rifle. Yet, it's only really useful in short-range, and in medium-ranged fights, it's likely to lose out to weapons of a similar ilk.
The Halo 4 version is the worst because it's fairly inaccurate. Halo 5 improves the gun by adding tracking bullets, which fixes the accuracy issue but doesn't raise the firearm out of mediocrity.
6/9 Boltshot, A Handcannon Transformed To A Burst Pistol
Even Prometheans need a sidearm, and they choose the Boltshot. In Halo 4, the firearm's standard shots are pretty weak. Yet, if you charge them up, they become extremely powerful. In fact, a charged shot is akin to a shotgun blast and can kill instantly.
However, Halo 5 removes this feature and makes it a burst fire pistol instead. The alteration isn't an upgrade as it's much less effective as a result. Although, the addition of tracking projectiles is welcome.
5/9 Scattershot, The Bouncing Shotgun
The UNSC shotgun is a classic Halo weapon that stands the test of time. However, humans aren't the only ones who can make a short-range gun. The Prometheans have done the same with the Scattershot. Although, this Forerunner alternative doesn't quite hold up to the original.
It can deal out serious damage, and the bouncing projectiles add a layer of unpredictability to the shotty. But it's not quite as deadly as the human version, mainly because you need to be even closer to get an instant kill with it. At least Halo 5 sped up its tedious reload.
4/9 Splinter Grenade, An Improved Promethean Explosive
Pulse Grenades didn't get the job done in Halo 4. Therefore, in the next game, 343 replaced them with Splinter Grenades, and it was certainly an upgrade.
These new ones explode on impact, once again. But this time, they release splinters which also blow up. And if anyone touches these little guys, they'll be in for some pain. It's so much more effective than a mostly useless sphere that does more to vehicles than it does to enemies
3/9 Light Rifle, Versatile Light-Based DMR
The Light Rifle is very different in Halo 4 than it is in Halo 5. During the fourth numbered game, the gun is unique as it has two firing modes. When shooting from the hip, it fires in three-round bursts. Then when you scope in, it becomes a more powerful semi-automatic rifle.
It makes the firearm very versatile, as you're basically carrying a Battle Rifle and DMR hybrid. However, Halo 5 ruined the fun by removing the three-burst mode.
2/9 Binary Rifle, One Hit Sniper
Few weapons in Halo history are as strong as this beast. It usually only takes a single shot to take down an adversary, even if it hits below the neck. This means it's an even more effective sniper than the UNSC one. Vehicles aren't safe from the sniper's power either, as most can't take more than a few hits.
The Binary Rifle isn't perfect, though. It only has two-shot rounds, plus the rifle is very visible from a distance, so enemies know to escape your line of sight. Halo 5 makes little alterations to the firearm, but not enough to ruin it.
1/9 Incineration Cannon, Risk And Reward
The Incineration Cannon is more than just a cool name. It's a heavy weapon that's a danger to everyone nearby. This is because it fires out multiple streams of explosives, which can cover a decent-sized area. And because of the insane damage it deals out, getting hit by part of the explosion is likely enough to kill you.
The user isn't safe either because if they fire too close to themselves, they're a goner too. It's the one downside to the cannon, but that's just what makes it so fun. Halo 5 adds a bit of variety to it by including a separate two-round burst firing mode. Thankfully, the thing is still very powerful after the changes.
