Halo: Campaign Evolved adds nine weapons beyond the full weapon selection in the original Halo: Combat Evolved.
The expanded arsenal brings weapons from later Halo games into the recreated campaign. Named additions include the Covenant energy sword, Battle Rifle, Fuel Rod Cannon, Sentinel Beam, and Needle Rifle, alongside other weapons such as the SMG, Brute Spiker, and Brute Plasma Rifle.
This is an addition to Combat Evolved’s original selection, not a statement that the remake contains only nine weapons overall. The original game’s familiar pistol, assault rifle, shotgun, sniper rifle, rocket launcher, plasma weapons, and other equipment remain part of the baseline comparison.
The change reflects Campaign Evolved’s broader remake philosophy: preserve the original campaign while modernizing its sandbox with later-era weapons, new missions, vehicles, enemies, and Skull modifiers. Consequently, a player counting every weapon in the remake would get a different number from the nine-item increase.
