Beam Rifle and Sentinel Beam
The Beam Rifle is a dedicated sniper weapon introduced as new to Halo Campaign Evolved, functioning as a reliable long-range tool. The Sentinel Beam, previously non-usable in original Halo CE, is now accessible after defeating Sentinels—though it does not drop from them in the original game.
How it works
- The Beam Rifle fires a high-damage, low-rate projectile ideal for precise long-range kills.
- The Sentinel Beam is obtained by killing Sentinels in Campaign Evolved, unlike in original CE where it was not dropped.
Source boundary: The Beam Rifle has limited ammo capacity and requires careful aiming; the Sentinel Beam is only available after eliminating Sentinels, limiting its early-game utility.

Needle Rifle and Fuel Rod Cannon
The Needle Rifle returns from Halo Reach, retaining its signature sound and behavior with minor functional differences from its original iteration. The Fuel Rod Cannon, usable in CE multiplayer on PC but not in original campaign, is now fully playable in Campaign Evolved, delivering heavy explosive damage.
How it works
- The Needle Rifle fires rapid, high-penetration needles that can pierce multiple targets in close quarters.
- The Fuel Rod Cannon launches a slow-moving, high-damage plasma sphere that explodes on impact or after a short delay.
Source boundary: The Needle Rifle’s range is short and accuracy drops significantly beyond medium distance; the Fuel Rod Cannon has a noticeable wind-up time and limited mobility while charging.

Brute Spiker and Brute Plasma Rifle
The Brute Spiker is a new addition to Halo CE, featuring an updated design since Halo 3/Reach with improved handling and visual fidelity. The Brute Plasma Rifle returns with a faster fire rate than the standard Plasma Rifle, though it overheats more quickly due to increased energy output.
How it works
- The Brute Spiker fires a single, high-impact bolt with a distinctive charge-up animation and recoil pattern.
- The Brute Plasma Rifle fires rapid plasma bolts at a higher rate than the standard version, but its heat buildup reduces sustained effectiveness.
Source boundary: The Brute Spiker has a slower reload and limited ammo per magazine; the Brute Plasma Rifle’s overheating may interrupt firefights if not managed with cooldown periods.
