Originally, a news van and a storm chaser served the purpose of following the tornado around and alerting the people within area to seek shelter or evacuate from their homes entirely.
Enabling free cam will reveal that a duplicate model of Zephyr is placed in the level's default position, which varies depending on the level.
An unfinished test animation for Zephyr and the Wind Warrior exists within the game files; the animation is named "surf"
Within the Xbox 360 and PlayStation 3's map files, there is a partially unused texture containing an early design for Nimbus.
Originally, instead of controlling a Wind Warrior in co-op mode, the player would have taken control of Nimbus. A partially unused transformation animation (which was re-purposed into a flying transition animation for the final game) and a stunned animation for Nimbus can be found in the game's files.
An unused idle animation for Nimbus exists in the game files. The animation is just called small_idle and has Nimbus' model shrunken down.
When it comes to emulation, the Nintendo Wii port of the game struggles to maintain 30 FPS on a handful of levels due to the large amount of objects being rendered on-screen.
Looking at the right side of the unlockable concept art for Showdown with Omegaton will reveal a gigantic dinosaur hiding in the water. Considering that this level takes place in Tokyo, it is most likely a reference to Godzilla.
The achievement/trophy Green Eggs and.... is a reference to the 1960 Dr. Seuss book, Green Eggs and Ham.

Enabling No-clipping mode in Chicken Con Carnage and heading back to the starting point of the map will reveal an unused spawn point for the L.O.A.D. STARR. Presumably, the level was intended to have two different zones.
An unused audio clip from the level Showdown with Omegaton suggests that Nimbus was originally going to tell Zephyr to pummel Omegaton's gigantic kidneys.
In numerous lines of the game's scripts, the vortex race is referred to as tpot. Player one, Zephyr is referred to as driver while player two, Wind Warrior is referred to as gunner.
Decompressing the tornadoalley.bsu file will reveal some hidden developer-related comments left by Scott Bilas, a programmer and audio engineer at Loose Cannon Studios
Within the data for every version of the game is a semi-functionable no-clipping mode that allows the player to freely explore maps without being stunned by the sunlight. The mode can be enabled by changing the value from "weatherphase1" to "weatherphase0". No-clipping mode doesn't work on Roadside Destruction, the tutorial portion of Chicken Con Carnage, and Showdown with Omegaton. Additionally, the player won't be able to destroy objects that are within the sunlight.
The Wii version of the game doesn't support widescreen. As a result, when the aspect ratio is set to widescreen, it will result in the display being stretched out.
The Stone Stomper has two unused pouncing animations that were intended to play during the Stone Stomp tutorial segment in Carnival Carnival. The first one, being a regular pouncing animation and the second one being a cannonball pounce.
The map Ringling Village features a statue of American writer Edgar Allan Poe. The crow standing on the statue is most likely a reference to The Raven, an 1845 poem written by Poe.
It is possible to grab and throw Nimbus with the tornado via modding. Since he doesn't have a death animation, his model will be stuck in an A-pose.
The ability to strip the clothing of certain humans was originally intended to be used for a side mission for Military Mayhem. The side mission in particular would've involved Zephyr pantsing the wandering soldiers in the first zone of the level.
Some of the tornado's sound effects were created by altering the sound effect of a tiger's roar.
As the game was originally intended to be a Wii exclusive, the colors for the tornado were colored coded after the colors of the Wii Remote's cursor. Player one, having a blue tornado while the second player having a red tornado.

The location for Ringling Village is loosely based off of Wiltshire, a country from South West England.
The player can unlock an piece of concept art of what is assumed to be the inspiration for Tornado Outbreak; a poorly modeled tornado with a high polygonal model of a cow.
A sprite for the Wii Nunchuk exists within the game's files. The purpose of this sprite remains unknown, but it can be assumed that it was intended to be used during the Totem battle segments. The player would've rapidly shake the Nunchuk until the Totem's arm was destroyed.
Two early names considered for the game during development were Tornado Alley, and Zephyr: Rise of the Elementals.
In both the regular and alternate ending to Showdown With Omegaton, a Wind Warrior can be seen holding his helmet.
The game runs on a modified version of the Granny 3D engine, a game engine developed by RAD Game Tools. Unlike most games that run on the engine, models, animations, maps and textures are compressed in a ZLIB archive.
The Xbox 360 port of the game is the only version that natively supports 60 FPS. The framerate on actual Xbox 360 hardware is capped to 30 but can drop down to 9 FPS, because of the render distance and additional lighting. When emulated, the game maintains a steady 30/60 FPS depending on what's going on. Cutscenes, subtitles and loading screens move too quickly, and there is major slowdown when the game is running in 60 FPS. This is noticeable in the sixth level Ringling Village and the final level Showdown With Omegaton.
In 2009, audio engineer and programmer Scott Bilas released the Wwise project file for the game. While the project itself doesn't include the original .wav files, it's possible to reimport them within Wwise.
By swapping map files, it is possible to play the first two single-player exclusive levels in co-op mode. The first level, Roadside Destruction, plays like a regular co-op level while the second level, Chicken Con Carnage, requires player one to take control of the tornado while the second player grabs the Fire Flyers. This mechanic was eventually reused during the Vortex Race and Totem Battle segments after completing all zones.
By modding the game, it is possible to completely disable the blue screen of death glitch. The outcome varies depending on the level, and in most cases the game either crashes or becomes softlocked, but some unusual results can still come out of disabling it. In the final zone of Chicken Con Carnage, restarting the level with the dialogue popup on screen will result in Nimbus sliding away from the camera while idling.
The player can unlock concept art for a completely removed level known as Drive-In, an early version of the map Roadside Destruction. While the map was entirely scrapped, music for the level was reused in Roadside Destruction and the Training Campground segment in Chicken Con Carnage.
An E3 2009 developer walkthrough revealed that the game had a removed mechanic called advance chain collecting, which completely removes the smoke, sparks, and sizzling sounds emitted from objects containing Fire Flyers. As a result, this changes the game's difficulty. It is possible to enable this mode in the Wii version of the game via modding.
Judging by the Tokyo Metropolitan Government Building featured in Showdown With Omegaton, it's assumed that the level's location takes place in the center of Shinjuku City.
Despite having an idle animation in-game, Nimbus' talking animation is used for both an idle animation and a talking animation. His actual idle animation is partially unused since its only used properly in the final level, Showdown With Omegaton.
The Wii version features two unused bonus cutscenes for the level Chicken Con Carnage. The first cutscene revolves around a news reporter by the name of Chuck Gavel reporting the strange animal behavior caused by the Fire Flyers possessing them. The second cutscene introduces a removed character named Wind Boy.
One early concept for the game revolved around the player constantly growing the tornado. If the player stopped controlling the tornado, it would simply shrink and dissipate.
The game has a game-breaking glitch that triggers a blue screen of death. This glitch possibly stems from a poorly-implemented anti-cheat feature as it can be caused in multiple scenarios, with two known examples being when two different dialogue pop-ups try to appear at once, and if you grab 100 Fire Flyers at once during the final zone of Chicken Con Carnage.
Completing the game with all the rock and water elementals collected will unlock an alternate ending that involves Zephyr, Nimbus, and the army of Wind Warriors returning to their homeworld.
By earning a gold medal in a handful of levels in the game, a blooper reel showing botched takes of cutscenes throughout the game is unlocked to view during the end credits.
The Xbox 360 and PlayStation 3 ports of the game feature a group of wandering Elvis impersonators in the map High Roller Blowout.
Despite not having a physical model, unused animations for the size 33 tornado exists within the game's files. Since no physical model is present for the size 33 tornado, the only way to properly display the unused animations is by swapping the tornado animations.
The game's cutscenes were animated using Adobe Flash and compressed through Bink Video.
Zephyr has an unused fumble animation that was intended to play right after the player stopped controlling the tornado.
Zephyr, the main character, has an unused animation that consists of him wiping both of his shoulders.
Setting the aspect ratio to 4:3 and replaying the credit segments will display both the Wind Warriors and Fire Flyers thanking the player for purchasing and completing the game.
The face of Derek McCaughan, a developer at Loose Cannon Studios makes an appearance on the tiny Tokyo citizens in the level Showdown With Omegaton.
In 2019, a tutorial video was recovered from a deleted hard drive. The tutorial video included a powerup known as the Fujita Frenzy that allows the tornado to instantly grow in size and destroy larger buildings.
Within the Wii's movie directory, there exists an unused two minute E3 2009 attract trailer that showcases an early build of the game.
The maximum size for the tornado is 33.
A side mission mode was planned but cancelled in the later stages of development.
In earlier builds of the game, the player was scored by both the amount of Fire Flyers collected and the amount of property damage caused.
