Sentinel beam

The Sentinel Beam is a Forerunner Direct Energy weapon that is equipped on a Sentinel.

Introduction
The Sentinel Beam is a Forerunner weapon connected to Sentinels to control outbreaks of The Flood. It appears as an orange beam of energy that can cut through the Flood parasite. The blue Sentinel beam is a stronger, more efficient version of the common orange Sentinel Beam and overheats less. In Multiplayer, the Sentinel Beam appears by default in the bases on Backwash and on Desolation.

Combat Usage
The Sentinel Beam is not player-usable in Halo: Combat Evolved. However, it is play-usable in Halo 2.

The Sentinel Beam runs on an non-rechargeable battery with a maximum charge of 100%. Like the Covenant's plasma weapons, it can overheat and will do so if 23% of the battery is used in one continuous stream. It is effective against the Flood and Sentinels, and can deplete shields like plasma weapons.

A continuous hit from a Sentinel Beam can be devastating against any opponent.

The beam used by the sentinels at Onyx were evidently a golden color and, while they took significantly longer to charge, were thought at one point to be capable of destroying a fully shielded Spartan. It may be worth noting that there were some other differences between the sentinels on Onyx and the ones in the games, as was pointed out by the character Dr. Halsey.

In Halo 2 campaign, the Sentinel Beam is a fearsome, all around good weapon. It sports a high rate of fire, amazing accuracy, and great damage against both shielded and unshielded opponents. The Beams reticule is also reasonably centered, providing quick centering of targets. The melee attack is about as strong as that of a rocket launchers. Two variants of the Sentinel Beam are seen in the campaign: The usual grey colored one that fires a red laser, and a gold colored one that fires a blue laser. The blue colored one is more powerful, but rare.

It is unknown if the sentinel beam will appear in Halo 3, for now it can only be speculated. But Bungie did mention it for a Humpday in the latest Weekly Update.

Trivia

 * When you destroy a sentinel and it's beam is picked up it only has 89 energy. This shows that enemies do not actually use up ammo but come with weapons with a preset amount.
