Xenogears

Xenogears is a well-known sci-fi RPG for PlayStation, which borrows heavily from various "giant robot" anime series, and was surrounded by a lot of controversy about its religious content back in the day. It also has a really, really weird storyline. And it's also very, very, very unfinished. Probably more so than SaGa Frontier, which speaks volumes.

Debug Room
Enter the following AR code based on your version: US Version: JP Version:

Now turn on your cheat device and start a new game, then turn it off.

Regurus
Elly's Omnigear, El-Regurus (or "El-Regrs", as it's called in the arena) is normally only seen in cutscenes, since Elly leaves the team permanently literally right before you'd get a chance to actually use it. Nevertheless, it still exists in the game in a fashion, and by using the Gameshark code, you can replace Fei's Gear with it. Unfortunately, the in-battle model and idle animation appears to be all that exists, as the game locks up immediately upon entering battle, and it has no out-battle model, causing the game to lock up if it's attempted to be displayed there, as well.

Other Gears
These Gears are not unused, but some text associated with them is.

The Deurmods used by Bart's generic soldiers have the internal name "BARTHOS". You can use the Gameshark code to replace Fei's Gear with one, but be aware that it has no out of battle model, and the game will crash in any situation in which it should be displayed, such as exiting battle.

The Yggdrasil-IV is used, alone, in a single battle early in disc 2, and never again. Its internal name is "YGGDRA", and can be given to Fei via the Gameshark code. Interestingly, it still towers over normal Gears, so it isn't merely a matter of "scale" in its fight against Ft. Hurricane. As with the Deurmods, the Yggdrasil-IV has no out of battle model, and will thus crash the game.

Unused Items
Enter in the AR code to add an item called Debug Item to your inventory.


 * Debug Item: Gives you every item in the game, including unused and debug items.
 * Debug Skill: Gives your chosen character all their deathblow skills, and puts every character in your party, including both versions of Citan and Emeralda. This will make the game crash in shops! Talk to Margie in the Debug Room to reassemble your party into something more stable.
 * Weak vs Wind: Makes character weak against wind?
 * Weak vs Earth: Same as above but with Earth.
 * Weak vs Fire: Same as above but with Fire
 * Weak vs Water: Same as above but with Water.
 * Stop!: Freezes character (just like 'stop' in FF games).
 * Sleep!:
 * Weakling:
 * Confusion: Confuses character
 * Armor loss:
 * EXP Ball:
 * Combo Ball 10: ?
 * Omni: Can be used in menu.
 * option:

Unused Equipment
There's a lot of unused equipment in the game, but the better majority of it does nothing, giving no stat boosts and having a sell price of 0G. There's also a glitch, in which if an item's name is thirteen characters long (including spaces), the last letter frequently gets overwritten by another random letter.

Weapons

 * ばるとよび ("Bart placeholder") - There are two of these. They can be equipped by Bart, and are, as the name suggests, just placeholders that were never filled.
 * したんよび ("Citan placeholder") - This is a katana that can be equipped by Citan. Another unused placeholder.
 * びりーよび ("Billy placeholder") - An unused placeholder gun which can be equipped by Billy, but no ammo works with it, so it can't actually be used.
 * ぶきよび ("Weapon placeholder") - Undefined placeholder weapons. Six of these exist, and they cannot be equipped by anyone.

Armor

 * Plain Clothes - There are four of these, all identical.
 * Ladies' Dress - Can only be worn by females, obviously.
 * LegendaryRobe - Despite its tantalizing name, this has no effect at all.
 * Slayer Robe - This male-only 108-defense piece of armor is not technically unused, but is virtually impossible to obtain, due to questionable design. It's dropped randomly (or always, if you have the Trader Card equipped) by Alpha Weltall... the problem is, the fight with Alpha Weltall is essentially rigged, as said opponent's attacks are prohibitively powerful, and if you had Citan in your current team, you'll only have two characters. Victory is technically possible, but very, very, very difficult, and even if you do win, the game assumes you lost, anyhow.

Headgear

 * PlainHeadwear - Useless.
 * Ladies'Bonnet - Can only be worn by females.
 * Stellar Cap - Can only be worn by females.
 * Men's Hat - Can only be worn by males.

Accessories

 * Coin of Fate - Doesn't appear to have any effect at all.

Gear Weapons

 * G-EthPistol - These are somewhat interesting. It appears that Billy's Gear, Renmazuo, was going to be able to use Ether Guns at one point. A full set of ammo for this also exists, with the same names as the standard human-size variety. Unfortunately, this cannot actually be equipped.
 * びりーよび ("Billy placeholder") - Another unused Gear gun for Billy which can't be equipped, this one just being an unfilled placeholder.
 * G-GatlingGun - The last unused Gear gun which, sadly, cannot be equipped.
 * ぶきよび ("Weapon placeholder") - Same deal as the human versions: Undefined weapons that can be used by exactly nobody. Again, there are six of them.

Gear Parts

 * F Circuit, G Circuit - A-E Circuits exist in-game, with various effects, but F and G were left unused and without any effects.
 * A Circuit+1, B Circuit+1, D Circuit+1, E Circuit+1, F Circuit+1, G Circuit+1 - Only the C Circuit has a "+1" version in-game. The rest of these exist, dummied out, and have no effect.
 * Customizer - Unknown. Doesn't seem to have any effect.
 * Hex - Unknown. Doesn't seem to have any effect.
 * Wind Stone - No effect, but this would probably have either raised defense against wind attacks, or gave the equipped Gear a wind-elemental attack.
 * Earth Stone - Same as above, except Earth-based.
 * Fire Stone - Same as above, except Fire-based.
 * Water Stone - Same as above, except Water-based.
 * (Blank Slot) - This item is somewhat interesting. It has a description ("Increase Guard's Restore") and an actual sell price (1,250G), but has no name. It's not known if it does anything, either.
 * Ar Guard - This one also has a description ("Prevents Armor Corrosion"), but the standard unused item 0G selling price. Again, it's not known if this works.

Unused Song


Famously, the OST features a beautiful lyrical rendition of the overworld theme called "Stars of Tears", which strangely, does not appear in the game anywhere. While it may have just been intended as a "bonus track", which is not uncommon on soundtracks, it is on the game disc(s), and can be heard in the debug room, where it accompanies a montage of the game's FMVs. It's unknown if or where it would have been used in the game proper, however.

Unused/Filler Face Portrait


A strange question mark graphic found with the face portraits. In all likelihood, this was intended to be used when an offscreen character spoke, but in the end, no graphic at all was used in these situations.
