Sentinel beam

Summary
The Sentinel Beam is a Forerunner weapon connected to Sentinels to control outbreaks of The Flood. It appears as a red beam of energy that can cut through most forms of the Flood parasite. The blue Sentinel beam is a stronger, more efficient version of the common orange Sentinel Beam and overheats less. Some think that the Sentinels use their beams to cut things like grass. That might explain why the plants in Halo: Combat Evolved were not growing on the buildings (of course, it could also just be a lack of detail in the game's design).

In Multiplayer, the Sentinel Beam will only appear in the bases on Backwash.

Like many weapons, it cannot be used in Halo: Combat Evolved.

Combat Usage
The Sentinel Beam is not player-usable in Halo: Combat Evolved. However, it can be used 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 most kinds of 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, and even a fully shielded Covenant destroyer, in one blast. 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.
