Pistol
Your first weapon, issued to you by Captain Keyes on the Pillar of Autumn. This is a fairly powerful weapon with a decent clip size, average ammo availability, and the ability to zoom. You'll want to keep this one on you at all times unless you need the weapon slot for something else (like the rocket launcher).
- Clip Size: 12 rounds
- Max Ammo: 120 rounds
- Zoom: 2x
- Reload Time: ~1.8 seconds
Assault Rifle
Your other first weapon, a rapid-firing carbine that holds 60 bullets, is not terribly accurate, and isn't too powerful either. Really only useful in the later levels or against smaller enemies like Grunts.
- Clip Size: 60 rounds
- Max Ammo: 600 rounds
- Zoom: None
- Reload Time: ~2.7 seconds
Shotgun
You only get this in the later levels, but it's a great weapon capable of taking many enemies down with one well-placed shot. It doesn't work too well over a distance, but the ability to eliminate Covenant Elites with a point-blank shot to the head is much welcomed.
- Clip Size: 12 rounds
- Max Ammo: ?? rounds
- Zoom: None
- Reload Time: Varies
Rocket Launcher
This one's great for taking down heavy artillery (like Covenant tanks) or large groups of enemies. It also zooms.
- Clip Size: 2 rounds
- Max Ammo: 8 rounds
- Zoom: 2x
- Reload Time: ~3 seconds
Sniper Rifle
A very powerful weapon for skilled sharpshooters. Quite nice for dealing with Elites, but only over a distance. Don't even bother trying to use it in close quarters, as the reload times will probably kill you. It also has a night-vision scope, which you can enable by turning on your flashlight while zoomed.
- Clip Size: 4 rounds
- Max Ammo: 40 rounds
- Zoom: 10x
- Reload Time: ~2.5 seconds (slightly more if empty)
Flamethrower
Good for clearing out trenches, around corners, or indoors. This weapon is only available in the PC/Macintosh versions of the game, and only appears in multiplayer.
- Clip Size: 100 units
- Max Ammo: ?? units
- Zoom: None
- Reload Time: ??
- Can overheat
Plasma Pistol
The most common Covenant weapon, very handy in a pinch, and excellent for taking out shielded foes (especially Elites). Holding the fire button will charge the weapon and deliver a very powerful homing shot.
- Max Ammo: 100 cells
- Zoom: None
- Reload: None
- Can overheat
Plasma Rifle
Another common Covenant weapon. You'll usually find this on Elites, sometimes on Grunts. It's not quite as good as the Plasma Pistol, in that it fires slower and cannot be charged.
- Max Ammo: 100 cells
- Zoom: None
- Reload: None
- Can overheat
Needler
The last common Covenant weapon and the only one that needs reloading. This weapon shoots slow homing "needles" that will explode after a short while of being stuck in something (or someone). It's not terribly useful and you'll probably only want it if you're out of ammo for everything you've got. The melee attack is the slowest in the game.
- Clip Size: 20 rounds
- Max Ammo: 80 rounds
- Reload: ~1.5 seconds
- Zoom: None
Fuel Rod Cannon
A battery-powered mortar launcher that is great for taking out players in vehicles, or shooting over obstacles. This weapon is only available in the PC/Macintosh version of the game, and only appears in multiplayer.
- Max Ammo: 100 cells
- Reload: None
- Zoom: None
- Can overheat
Frag Grenades
One of two types of grenades you can find. These will bounce around corners and explode in a fairly large radius, killing whatever happens to be near.
- Max Ammo: 4 grenades
- Detonation Radius: ~8 meters
- Timer: 2 seconds (starts on first bounce)
Plasma Grenades
The Covenant's answer to frag grenades. These are about as powerful as Frags, but they don't bounce as much and will stick quite easily to enemies and friends alike if hit directly with them.
- Max Ammo: 4 grenades
- Detonation Radius: ~8 meters
- Timer: 3 seconds (starts on throw)
