Gameplay

Unlimited Energy Sword

From Halopedia, the Halo wiki

The Unlimited Energy Sword exploit is a weapon-related glitch in Halo 2 and Halo 3's Campaign. The glitch only works on single-player Campaign; Co-op will not work.

Walkthrough

All a player has to do is finish the first of any two connected levels with an empty Energy Sword and any other weapon. During the second level, the Energy Sword will still be empty and will appear to have no blade, but the player will be able to attack with it.

Note that when finishing the first of the two connected levels, the player's other weapon must have ammo; if the player finishes with two empty weapons, they will start the next level with default weapons. Also note that if a player switches the Energy Sword for another weapon, they will not be able to pick the sword back up.

Levels this glitch works on

Halo 2 (Still works on the MCC)

Halo 3

Does not work on the MCC edition anymore because 343 fixed it by not spawning any swords in the mission before. Kiling the Arbiter also doesnt spawn a sword as he did in the original Bungie games

Does work on the MCC edition partly because 343 fixed it. You can get a Sword in the mission before but you will auto equip your second weapon on arrival after the Cutscene and the sword despawns because its empty. So you start with only one weapon If you try this. But you can get the unlimited Sword after rescuing Cortana If you take her with the empty word in your hand and a carabine as secondary.

Trivia

  • When wielding an empty Energy Sword while using Active Camo, the sword's two blades can be seen.
  • When the player switches the "Unlimited Energy Sword" on, the hilt will flash.
  • This glitch will not work for Gravemind and High Charity, even if you hold onto an Energy Sword.
  • If the player gets in a Warthog passenger seat and equips the sword, the blades will be visible.
