It is a well known fact within the Halo community that Halo 2 was rushed to release, and although the finished product is a great game, it wasn’t as polished as the developers would have liked, particularly in some areas of the campaign. This is great news for players, who in the time since the game’s release have found a multitude of ways of exploiting glitches in the game’s physics engine to explore outside the levels in the campaign, which the developers actually filled with Easter Eggs knowing that this would happen. Some of the glitches in Halo 2, however, are less to do with the lack of level boundaries and quirks with the physics engine and more to do with specific objects or enemies in particular levels that, to the uninitiated, may come across more like Easter Eggs – and for all intents and purposes they are, albeit unintentional ones.

10 – Needler Sentinel – Quarantine Zone

The origins of this particular glitch are somewhat unclear – either Bungie originally intended for Sentinels to carry and use weapons other than their usual energy beams, or it was simply a one-off error with the coding of this particular Sentinel – but either way, in a particular room on the game’s eleventh level, the player encounters a massive firefight between Sentinels and Flood combat forms that can get pretty hectic. In the chaos, it can be hard to miss this one particular Sentinel that fires Covenant Needler rounds instead of the Sentinel Beam, and when it is destroyed, it drops a Needler. Interestingly, the Sentinel Enforcers do use a weapon similar to the Covenant Needler, but that weapon fires red shards instead of purple, and Sentinels are never seen wielding that weapon either. Bungie employees have given varying explanations for this, from an accidental ‘slip-of-the-mouse’ when the level was being coded to an entirely cut feature in which Sentinels would use their own version of the Needler on occasion – regardless, it is an interesting glitch.

9 – Sergeant Johnson Drops Dead/Four Sergeant Johnsons – The Great Journey

This glitch is actually two (or perhaps even three) glitches at once, all in the same place on the same level, but they essentially amount to the same result. If the player can manage to maneuver a Covenant Spectre into the final room of the final level of Halo 2 – no small feat – one can actually use the vehicle in the final boss against the Brute Chieftain Tartarus, and can even convince Sergeant Johnson to climb aboard. As Halo 2 veterans will known, Johnson is crucial in the final fight against the Chieftain as he uses a Covenant sniper rifle to lower the Brute’s shields, thereby allowing the player to deal the fatal blow. Due to a strange glitch in the design of the three-tiered arena, however, crouching on the lowest level will cause the player or any other character to drop dead instantly, because you technically intersect with the death barrier that prevents you from falling beneath the floating structure. If one can maneuver Johnson in the Spectre onto the bottom level and cause him to climb out, and because Johnson always crouches after exiting a vehicle, the normally invincible Sergeant will drop dead, allowing you to loot his weapon.

Also, using the same method of getting Johnson in the Spectre, the player can amass a small army of Johnsons since the game automatically spawns a new Johnson when the old one moves too far away from his sniping spot – undoubtedly to keep the battle fair in case Johnson somehow falls. With one Johnson on the powerful plasma turret and two Johnsons riding shotgun, plus another Johnson occupying the sniping spot, this glitch can seriously tip the balance of the boss fight in the player’s favor.

8 – Bullying the Heretic Leader – The Arbiter

For those who played the first two Arbiter levels and thought “How is the Heretic Leader always one step ahead?” and aren’t quite satisfied with finally killing him at the conclusion of the level The Oracle, on the original version of Halo 2 for the Xbox it is actually possible to reach him early and essentially beat him up – you can toss grenades at him, throw him into a chasm, or even drop a Banshee on him, and yet he will simply refuse to die. For this to happen, you must equip an Energy Sword in the scene in which the Heretic Leader is visible through a window giving orders to his men and then climbing aboard a Banshee to escape your wrath once again. If you time it right, it is actually possible to use the sword’s lunge attack to clip straight through the window and hit the Heretic Leader directly. Now simply use a grenade to render his Banshee inoperable and he will just stand there, as if accepting his fate. It should be noted that doing this makes the level impossible to complete, and as previously mentioned this only works on the original Xbox version of Halo 2, so it might be more trouble than it is worth at this point. Still, a fun time-wasting glitch that is actually one of the few glitches in the game to be patched in later re-releases.

7 – Exploring ‘Lake Regret’ – Delta Halo/Regret

Who doesn’t love exploring outside level boundaries? This particular glitch can allow players to not only explore outside the usual confines of the levels Delta Halo and Regret, but it also demonstrates the Master Chief’s less-well known ability to breathe underwater indefinitely, something that comes in very handy when walking across the bottom of a deep lake Pirates of the Caribbean-style. To accomplish this, one has to simply use a grenade to propel the player onto the hills around the final part of Delta Halo or the first part of Regret, and then simply walk around the lake to find a point in which it is possible to walk into the water. Falling into the lake is not a good idea, since fall damage will usually kill the player on contact, but another method that involves using a Ghost to climb the grassy verges around the level can speed things up a bit. (This is easier with the Sputnik Skull enabled that allows the player to propel themselves further with explosives). Once in the lake, the player is free to wander around, study the architecture of Regret’s temple that seems to float on the lake with the supports cutting off about 3 feet beneath the water’s surface, listen for the sound of invisible Whales, and find a large and ominous hole in the floor that seems to serve no real purpose whatsoever.

It should be noted that, although not included here, the well-known ‘Vacations’ that can be taken on almost every Halo 2 level (using similar methods to exploring Lake Regret) constitute their own ‘sub-category’ of fun and interesting glitches. In fact, that might be the subject of another article later down the line…

6 – Knock the Prophet out of his Throne – Regret

Speaking of the Prophet of Regret, another fun glitch allows the player to temporarily remove the shriveled Covenant hierarch from the safety of his Gravity Throne. During the boss fight with him at the end of the level Regret, the throne must be boarded in order to injure the Prophet as his shields absorb anything the player can throw at him from overcharged Plasma-Pistol shots to both barrels of a Rocket Launcher. However, since Regret’s throne is treated like any other vehicle in order for the boarding mechanic to work, with enough explosive force the player can flip the throne over and, like all occupants of a flipped vehicle in Halo, Regret will be forcibly ejected. Interestingly, the Prophet will simply sit on the floor in the same position as if he were occupying his throne and then attack the player with a Plasma Pistol of all things. This alludes to the fact that in the Halo novels he and most other Prophets are depicted carrying at least one Plasma weapon as a sidearm, and the Prophet will actually drop this pistol upon death whether he is in or out of his throne. This glitch is tricky to pull off, and it is recommended that either the Scarab Skull or weapons like the Fuel Rod Gun or Needler are used since only these can create enough inertia to bounce Regret out of his seat.

5 -Miranda in Space – Cairo Station

For those who are not convinced that Miranda Keyes is an unmitigated badass, this glitch confirms that Miranda Keyes can actually breathe in space. Using an Energy Sword on the level Cairo Station, it is possible to push Keyes (or Johnson, for that matter) past the point in the level in which they would usually leave the Chief and through an airlock, and as they are programmed to be invincible the repeated strikes will not kill them. By eventually pushing them into a section of the level that they are never supposed to enter, the player can actually push the naval officers into space, as the next section of the mission requires Chief to exit the station and fight Covenant EVA troopers. Though they need the player’s help to get through the level, Keyes and Johnson will attack enemies that are nearby and speak to the Chief, despite the fact that they are in a near-vacuum without any protection whatsoever. Oddly, they will de-spawn if the player attempts to push them back into the station later in the level, and nudging them off the station and into the vast abyss of space will cause them to drop like a rock, still adopting a combat-ready pose as they plummet into the Earth’s atmosphere.

4 – Plasma Grenade Fountain – The Oracle

This is another glitch that exploits the Heretic Leader, specifically one of his holo-drones. At the start of the game’s seventh level, the player encounters a hologram of the Heretic Leader that taunts you and your allies before disappearing. However, in the game’s code, this hologram is treated as an enemy – and if you melee it with the Piñata Skull on in Halo 2: Anniversary, it will drop Plasma Grenades in abundance. Using the faster swing of the Energy Sword means that in the brief time the hologram is present the player can spawn dozens of grenades, and this can cause a massive explosion if they are all detonated at once.

3 – Permanent Invisibility – Chief Levels

In the original Halo 2 for the Xbox, Skulls had to be found and activated in levels on Legendary, and the effects of the skulls only lasted until the console was switched off. This was done because, at the time, there was no menu option to activate and deactivate Skulls, they were merely included by the developers as wacky Easter Eggs. As a result of this, acquiring the Envy Skull in the original Halo 2 and using it just as a checkpoint passes, saving and exiting, and then restarting the Xbox and loading up the level will cause the Chief to be permanently invisible. This works because the Envy Skull trades Chief’s flashlight for Arbiter’s active camouflage, a feature that he can never acquire in regular gameplay, but only for the time in which the Envy Skull is activated. Because switching off the Xbox deactivates the Skull, saving and exiting a level while Chief is still invisible means that, after the Skull is deactivated, the game cannot revert him back to normal visibility and the player will be able to sneak up on unsuspecting enemies and eliminate them at their leisure. This glitch is most useful on Legendary, but it can only be used in levels in which Chief is the playable character.

2 – Cortana’s Scary Face – The Great Journey

This glitch is a result of the feature in Halo 2: Anniversary that allows players to switch back and forth between the classic graphics and the updated, remastered graphics created by 343 Industries and Blur Studios. At the conclusion of the final cutscene of Halo 2 when Cortana accepts Gravemind’s offer of answering his many questions about Humankind and the Covenant, switching from new graphics to classic graphics at the last second of the cutscene after it cuts to black will present the player with this abomination – clearly Cortana’s rampancy is taking its toll. This is caused in part by the fact that the remastered cutscene is longer than the classic cutscene was, and so switching back shows the player the models after the cutscene has technically already finished, and is also due to the fact that the camera has panned inside Cortana’s head, leaving only her eye visible. Hilariously, this glitch is also accompanied by the spooky final few notes of the Halo 2 Soundtrack’s Epilogue.

Honorable Mention – The ‘Ghosts’ of Halo

This phenomenon caused quite a stir when it was first discovered in the early days of Halo 2 on Xbox Live. According to legend, players on maps such as Lockout on Xbox Live began reporting sightings of strange characters that resembled other players but lacked a gamertag, movement animations or a place on the scoreboard – these ‘Ghosts’ would reportedly kill players by sliding around the map and tossing grenades in all directions, and in certain cases they were apparently un-killable. Various explanations for this odd occurrence were suggested throughout the fanbase such as the ‘Ghosts’ being a result of a glitchy network connection, but other more ludicrous theories sprung up such as the idea that Bungie employees had programmed bots into the game, that Microsoft were spying on players or that the maps were legitimately haunted. Ultimately, confirmed sightings of the so-called ‘Ghosts’ that haunt various multiplayer maps of Halo have been scarce since Xbox Live has improved, which would suggest that the phenomenon was a result of little more than a bug in Xbox Live or a dodgy network connection, or that the entire thing was a hoax. Either way, the ‘Ghosts’ of Halo are still regarded among the game’s most infamous glitches.

1 – The Honour Guard Councilor – Gravemind

Halo 2 had numerous boss battles in the game, ranging from our old friend the Heretic Leader to the Brute Chieftain Tartarus, but one boss fight in the game was actually created by accident as a result of a glitch in the game’s code. The final enemy of the mission Gravemind is an Elite with a unique set of armour that changes each time the level is played – sometimes the Elite will have an Honour Guard helmet, a Councilor helmet, or even no helmet at all – but the armour will always be white with the gold and black spurs of the Honour Guard. This mini-boss with unique randomised armour is actually the result of the game trying to spawn an Elite Zealot that was coded with the wrong tags, causing the Elite to spawn with widely varying armour and much higher shield strength. Strangely, the Elite can sometimes spawn with the face of Rtas ‘Vadum, an ally to the Arbiter throughout the Halo 2 and Halo 3 campaigns, and sometimes the Elite spawns with a strange and unique helmet that was coded into the game but never allocated to any characters. This visually unique accidental mini-boss is arguably the best example of how good some of the glitches in Halo 2 actually are – although the game is riddled with bugs like these, it doesn’t negatively impact the gameplay, and instead serves to make the game that bit more interesting.
