MC6Pistol

Effectiveness: Low.

Assault Rifle

Effectiveness: Medium. Very common and popular weapon. Finding ammo for it should not give you any difficulties.

Battle Rifle

Effectiveness: High. This gun is one of the most effective in the whole game and it has more firepower than in Halo 2. Use zoom and aim at Brutes' head.

Sub Machine Gun (SMG)

Effectiveness: Medium. SMG ammo is relatively easy to find (especially in levels where you are fighting the Flood). It's not very accurate but can be useful against Drones.

Shotgun

Effectiveness: Medium, but only at short range. It's not as commonly used as in Halo 2, since many other weapons you have at your disposals are more effective against the Flood.

Sniper Rifle

Effectiveness: Very high, but you don't get too many occasions to find the weapon.

Rocket Launcher

Effectiveness: High, but only at a distance. Used mostly against vehicles or large enemy groups. Rare weapon.

Spartan Laser

Effectiveness: Very rare weapon used mostly against vehicles.

Grenades

Effectiveness: Very high. There are three types: common frag grenades; plasma grenades and incendiary grenades (Molotov Cocktail type).

Flamethrower

Effectiveness: Medium. Very rare weapon. It could be useful against the Flood but it has very short range.

Machine gun/Plasma turret

Effectiveness: Very high. In Halo 3 you can take turrets with you, so do it when you get the chance.
