Night Warriors: Darkstalkers' Revenge (Arcade)

The sequel to Darkstalkers, Night Warriors made the previous game's two boss characters playable, added two new characters, refined the game's systems and added many new moves. Some materials that were used in the game's location test builds remain unused in the finished version, along with various other abandoned ideas.

Darkstalkers leftovers
A whole boatload of graphics from Darkstalkers such as select screen graphics go completely unused in Night Warriors, as per direct inheritance.

Blizzard Sword
In the location test versions of the game, Donovan's Blizzard Sword special was completely different from the version seen in the finished game. Rather than firing a snowflake projectile that traveled in a shallow arc, it caused Donovan's sword Dhylec to fall from the top of the screen, covered in ice. The sprites for this version still exist unused in the finished game. This version is also featured on the game's official flyer.

Kill Shred
Donovan's Kill Shred special sends his sword Dhylec spinning through the air at the opponent. However, in the location test version, it spun in a different orientation as compared to the finished game.

Furthermore, rather than staying at the center as in the finished game, this version's hitbox clung to the spinning edge of the sword, thus covering a much larger area and making the attack much more effective.

Final Guardian
bjTZ_IcQ4Lg Huitzil's Final Guardian move causes him to turn into a gun turret and fire several exploding shots. However, in the location test version of the game, the move caused Huitzil to summon a backup robot which would turn into the gun turret, which Huitzil would then fire. Video of this version of the move can be seen in the promotional video to the right at around 2:45. Sprites for this version still exist in the finished game.

The backup robot has a slightly different design from Hutzil, noticeable in the face and chest. So when the move was changed to have Huitzil himself turn into the turret, all of the sprites (except one) were modified accordingly. Both versions exist within the game's data. This frame originally intended for the support robot's arrival and departure is actually still used in the beginning of move's animation in the finished game despite not being redrawn. This Huitzil pose for operating the turret also still exists. Like the Blizzard Sword, this version also ended up on official flyers.

Ground Slam Hitspark
A hitspark seemingly intended for moves in which the opponent is slammed against the ground exists unused. Unlike the rest of the hitsparks drawn in this style which play two animation sequences in succession, this one flips between the two sequences on a frame-by-frame basis.

Angled Speed Lines
Many angles exist for the speed line sprites seen on dashing characters, although only the straight horizontal ones are actually used.

Alternate Speed Lines
Stored next to the normal speed line sprites is what appears to be a set of alternate, animated speed line sprites. They are also drawn in multiple angles.

Dhylec Surfboard
Donovan's spriteset contains an unused animation of his sword Dhylec becoming a surfboard. According to a developer interview in "All About Vampire Hunter", they floated the idea of having Donovan surf when confronted with Rikuo's Sea Rage (an EX move which launches a tidal wave at the opponent).

Pyron Alternate Dash
Pyron's spriteset contains an alternate unused dash animation. His normal dash animation uses the same flare-covered sun graphic as his jump.

Final Guardian Combiner Variant
Yet another alternate concept for Huitzil's Final Guardian move exists within the game's data. This animation also involves the support robot seen in the location test version, but here it combines with Huitzil to form add-on weaponry which is then fired.

Confusioner Muzzle Flash
A muzzle flash-like effect intended for two of the frames of Huitzil's Confusioner-firing animation exists in the data but goes unused.

Huitzil Breakfall
Despite having been redrawn, Huitzil's breakfall animation goes unused again. The first frame of this animation ended up being re-purposed into the startup of his Final Guardian attack in the Saturn port.

Tutankhamun Mask
This puzzling gigantic Tutankhamun mask exists within Anakaris's sprites.

Khaibit
This game marked the debut of Anakaris's helper, Khaibit. In the finished game, he only appears controlling the bottom half of Anakaris's Pharaoh Split, but it would appear that there was much more planned for him. Some of these graphics would go on to be used in the next game, but others were never used at all. Anakaris produces a spinning Khaibit. This would later be used for his Word of Truth guard cancel move in Vampire Savior, although whether they intended similar functionality here is unknown. It would seem that at some point it was intended for the opponent to be able to attack Khaibit, as his has several damage animations prepared, including: High and low standing hit reels... Knockdown animations... Electrocution and burn animations... Horizontal spin and trip animations... And even sliced in half animations.

Pharaoh Split
Anakaris's Pharaoh Split EX move temporarily separates the upper and lower halves of his body, allowing them to attack the opponent in tandem. Some animations related to this move go unused, hinting at functions that aren't featured in the finished game. Idle, forward dash, and back dash animations for the lower half. Normally the lower half automatically walks forward, and the player can only make it attack. The last few frames of the idle animation are actually used in the finished game as additional recovery time after attacks. Hit reel and blocking animations for the lower half. Normally it's completely invincible and cannot block or be hit by any attacks. A special hit reel for Anakaris's flying upper half. Normally when Anakaris's upper half is hit, he reacts as he normally would when hit in midair and the lower half disappears.

Text
A "Player Select" label that goes unused in the actual select screen. Guard type selections that are in a different font from the ones used, as well as worded differently ("manual" as opposed to "normal").

Unused Sounds
Felicia Screech A voice clip of Felicia screeching. This goes unused in this game, but would later be used for her EX Charge in Vampire Savior. Felicia: "Katta!" A voice clip of Felicia saying "Katta!" ("I won!"). Although the full clip goes unused, the "ta" was cropped and used for her ES Delta Kick.

Development Text
Some leftover development text, much of which seems to date back to the development of the previous game, exists in the ROM data near the text for the standard option and test menus. Since much of it is in romanized Japanese or heavily abbreviated, I have taken the liberty of adding some supplemental explanations in parentheses, those are not part of the original text.

Character Name Placeholders
It would seem that the characters' names were not decided until late in the development process, as these development labels simply refer to their species/type.

Animation Labels
Text labels for character animations, both general and character-specific exist, although the latter are in varying stages of completion.

Regional Differences
In the Japanese version, when you defeat the last boss, you get the character's ending and then you get a scrolling drawing of the character accompanied by an epilogue. In the non-Japanese releases, this epilogue was completely removed.

Voices
In non-Japanese versions of the game, most Japanese voices were removed except for grunts and cannot be enabled by normal means, and there does not seem to be a way to reinstate the voices via the test menu.

Revision Differences
In the 950302 build, Huitzil's jumping medium punch trips standing opponents on hit. In subsequent builds it causes standard hitstun.

In the 950302 and 950307 builds, opponents trapped in Rikuo's Water Jail bubble cannot be hit by certain attacks, including Sonic Wave, Poison Breath, Aqua Spread, and Sea Rage. In subsequent builds, these attacks can hit opponents while they are trapped in the bubble.
