What is your favorite weapon? Mine is Spartan Laser.

Assault Rifle
Assault Rifle The Assault Rifle has been brought back from the first installment in the Halo series with a few modifications like greater accuracy, more range, and more damage per hit. Accuracy is high when fired in bursts, and the overall accuracy of this weapon is good at medium ranges (even higher at close). This is a very good all round weapon that can be effective in almost all situations if used correctly, and is an even better weapon with grenades, and melee attacks (this goes with any weapon).

Battle Rifle
Battle Rifle The Battle Rifle was one of the most popular weapons in Halo 2 for players with good aiming. In Halo 3, Bungie has balanced the weapons in a way that doesn't overshadow other weapons, yet not underpowered. With reduced aim assist, this weapon takes even more effort to be used effectively. And the new, heavier, sound is so rewarding. You're in a battle. Bring your Battle Rifle.

Beam Rifle
Beam Rifle The Covenant beam rifle appears to be the Covenant forces' answer to the Sniper Rifle. Very little information has been confirmed about this weapon or its potential capabilities. This weapon does not use ammunition and will overheat when fired too quickly for too long, keeping the Beam Rifle on par with the human Sniper Rifle.

Brute Shot
Brute Shot The Brute Shot has been changed, going from a hard-to-find but effective weapon to a mainstay of campaign and a solid choice in multiplayer. It fires grenades which explode on contact, doing serious damage, especially in confined spaces.

Covenant Carbine
Covenant Carbine Unlike the Battle Rifle, the Carbine has seen few changes since Halo 2. It remains a powerful, accurate semiautomatic weapon with a moderately-sized clip. Because of the changes made to the Battle Rifle, however, the Carbine is now far more accurate than its human counterpart, and is rapidly overcoming the second-class status it had in Halo 2.

Energy Sword
Energy Sword The Energy Sword (also known as the Plasma Sword) returns, with a battery and a reduced lunge to bring it into the overall balance. It also has specific medals attributed to it.

Flamethrower
Flamethrower The flamethrower is a support weapon, strong against both vehicles and ground units, but balanced by a relatively short range and limited ammunition.

Fuel Rod Gun
Fuel Rod Gun A heavy Covenant weapon that is a counter to the Rocket Launcher. Before Halo 3 it was only available for multiplayer use in Halo PC.

Gravity Hammer
Gravity Hammer A weapon similar to that of Tartarus' in Halo 2. A melee weapon that has a lunge shorter than the energy sword but has the power to knock back projectiles or vehicles out of the way.

Machine Gun Turret
Machine Gun Turret Remember being sniped in Halo 2 when you were using the turret? This time round you can pick up the turret and move position! So no more easy target for snipers. Not only can you walk with this thing but its more powerful and the aim too has improved. Go take out their whole team or that one annoying Mongoose!

Magnum
Magnum The M6G Magnum is a dual-wieldable semiautomatic pistol that does great damage to shields and flesh, has a headshot bonus, and is accurate out to medium range. It resembles Halo's M6D Magnum, but lacks a scope and does slightly less damage.

Mauler
Mauler A dual wieldable Brute shotgun that has less power than the human varient when single wielded, but can be more powerful when two are wielded.

Missile Pod
Missile Pod One of the new support weapons introduced in Halo 3. Like all support weapons, it slows the player and forces a third-person perspective. The missile pod can be thought of as a rebalanced answer to Halo 2's tracking rockets: it has a larger ammunition capacity than the rocket launcher and is capable of tracking vehicles, but each missile does less direct and splash damage than a rocket.

Needler
Needler he Needler is back and more powerful than ever! However, it is now only single wieldable. But can seriously pack a punch at mid-close range.

Plasma Cannon
Plasma Cannon he Plasma Cannon, like it's Human counterpart, the Machine Gun, is a 3rd person Support Weapon that can be pulled off from the covenant turrets on a level.

Plasma Pistol
Plasma Pistol The Plasma Pistol is the most basic of the Covenant weapons. The non-charged shot has little use. However, the overcharge can completely deplete enemy Shields allowing an easier kill with other weapons or it can overheat a vehicles engine, not allowing it to move for a few seconds. Pistol Whips! However it still allows the turret on the Warthog to fire.

Plasma Rifle
Plasma Rifle A rifle of Covenant origins that fires plasma bolts at the enemy. Like most Covenant weapons that fire plasma it helps to deplete shields faster than Human weaponry.

Rocket Launcher
Rocket Launcher The rocket launcher oncemore has no vehicle lock-on. That attribute was lost to the Missile Pod. In the Beta, the rocket had slight auto aim, it would bend course very slightly towards a player.

Sentinel Beam
Sentinel Beam A laser or Forerunner origin. The weapons of the sentinels. The Sentinel Beam is a battery powered laser.

Shotgun
Shotgun The shotgun now sees a slight reduced clip. But is still devastating at close range.

SMG
SMG No longer the default starting weapon as it was in Halo 2. This weapon is still dual wieldable. It works well at close, to medium ranges and is considered to be similar to the Spiker. The SMG has increased accuracy and range, making it much more effective than it was in Halo 2. The SMG also has a faster rate of fire.

Sniper Rifle
Sniper Rifle Long Range Sniper rifle with 5-10x scope. The Sniper Rifle can kill faster than Any other weapon in the game, due to its Single head-shot kill ability. It is the most inferentially accurate weapon in the Halo series. It's Covenant counterpart is the Beam Rifle. It is rare to find multiple Sniper Rifles on maps. It is favorite to most long-range shooters. It is a VERY powerful weapon (boasting single head-shot kills and two shot kills on the rest of the body) It now has a Night-vision scope (on the scope display when not scoped-in). The Sniper Rifle is VERY effective at long ranges, but can also be effective at Medium ranges, or Close ranges if used correctly.

Spartan Laser
Spartan Laser Portable Power! The Halo 3 Spartan Laser is one of the new members of the Halo armory. It is designed for anti-vehicle use, but is also very effective as an anti-personnel weapon. The directed energy mechanism fires a highly charged laser beam that, if it hits, totally destroys the target. A brief charge time before firing and a small laser "pointer" coupled with humming noise makes surprise attack with this weapon somewhat tricky, but players caught out in the open against the Spartan Laser are usually left counting down to their respawn.

Spiker
Spiker What some people call it the brutes SMG. It shoots out the spikes like the Spike Grenade.

my favprite is flamethrower but i hate the way it goes so slow and short range. but its still my favorite weapon!

laser are really cool to i would say flamethrower is my 2nd or 3rd favorite weapon
