Unlike the plasma grenades used by the Covenant, human fragmentation grenades bounce, rather than stick, when they hit surfaces or targets. Like the plasma grenade, you can carry a maximum of four at a time.

Detonates after one half of a second after impact, and has a blast radius of 15-30 feet.

UPDATE: This weapon is expected to be in Halo 3. Exact designation and specifications are unknown. However, it is expected that due to the addition of Spike Grenades, the maximum number of frag grenades you can carry will be reduced from four to three.

UPDATE: In the Halo 3 Public Beta, the number of grenades per type that can be carried simultaneously is in fact two.

The human sniper rifle is changed slightly from the first game. It now has recoil, requiring the user to aim again between shots. When holding the weapon and not using the zoom scope, a "live" image is displayed on the scope.

The sniper rifle cannot be dual-wielded.

The scope provides 5x and 10x zoom. The rifle magazine holds 4 14.5mm armor-piercing, fin-stabilized, discarding-sabot rounds. It is generally only useful at medium or long range due to low capacity and long reload time.

The shotgun in Halo 1 was a short to medium range weapon with middling accuracy and real stopping power at short range, capable of one-shot kills for most unshielded targets. Reportedly this weapon is little changed from the first game.

The shotgun cannot be dual-wielded.

The shotgun holds 12 8-guage rounds and is most effective at close range.

The rocket launcher in Halo 2 has slower projectiles than the SPNKR from the original game, but if you get a lock on a target, the projectiles will seek. Especially good against vehicles. Damage radius is also reduced.

It cannot be dual-wielded.

The sub machine gunfires faster than Halo 1's Assault Rifle, and can be dual-wielded, but is not very powerful.

The SMG's magazine holds 60 5mm rounds and fires them in a fully automatic mode. Not accurate at long distance.

The Battle Rifle fires 3-shot bursts in normal mode and single shots while zoomed.

It is widely thought of by some as a combination between Halo 1's too-powerful pistol and too-weak Assault Rifle. The submachine gun, or SMG, is perhaps more comparable to the Assault Rifle.

The Battle Rifle cannot be dual wielded.

The BR55's magazine holds 36 rounds of 9.5mm ammunition. The Halo 2 manual refers to it as a "useful all-around infantry weapon."

The pistol in Halo 2 has no scope for zooming, unlike Halo 1's pistol, and it is less powerful. However, it can be dual-wielded.

It is magazine fed and uses 12.7 mm armor-piercing rounds. The magazine holds 12 rounds and fires in semiautomatic mode.
