BIT.TRIP FLUX is the final game in the original BIT.TRIP Hexalogy. The game is something of a bookend to the series, playing identically to that of BEAT, only on the opposite side of the screen. It has a light, gentle, and comforting tone, if slightly somber due to its overarching themes of death and finality.
CommanderVideo is dead. Before he can ascend to the afterlife, he must return home, looking at his life from beginning to end, learning to let go of the ones he held dear, and view his accomplishments as a whole picture. Only once he is able to open his eyes and see, will his, and by extension, the Player's BIT.TRIP truly be complete.
The title theme, Strange Comfort, was specially composed for this game by guest composter Bit Shifter
HUD[]
The HUD is like the BIT.TRIP BEAT HUD, but everything is reversed; as in, what was on the left is now on the right and vice versa.
MODES[]
As the final game in the original series, the highest MODE has been made available. Please note these are listed from highest to lowest.
This is the highest mode in the game. The HUD takes on a sharp red-and-white palette. The Paddle is a solid Red, and the progress bars fade from red to white, and back to red again in a large gradient. The text becomes monochromatic, and the specifics of its design depend on the stage. The Beats make sounds of the violin family. The score multiplier reaches a whopping x500. Achieving a MODE-Up will award a MULTI+ bonus multiplier, which will increase the current score multiplier by 1 each time it is achieved.

GIGA appears very similar to HYPER at face value, possessing a similar, but darker magenta hue. The text has a sliding gradient effect which gives the effect of tilting left and right in 3D space. Every Beat makes a gentle, echoing acoustic guitar tone. The multiplier hits x200 when you MODE-Up to it. Doing well here will allow you into the game's, and series' highest MODE, META.

EXTRA Mode is the mode up from ULTRA. The HUD gains a "neon" look to it, becoming clear with brightly colored borders. The borders themselves cycle through random pastel colors in time with the cascading effect the text has, similar to how EXTRA appeared in FATE. The Paddle mirrors this stile, gaining a somewhat chunkier appearance in this MODE. Every beat makes the sound of a note played on an electric piano. Your multiplier changes to 100x upon reaching this MODE. The next MODE-Up is GIGA.

ULTRA removes the gradient effect but keeps the soft scroll through rainbow colors. The colors themselves are a bit brighter than in SUPER as well. Additionally, the labels for the next and previous MODE scroll from left to right. Every note makes a soft, windy sound upon hitting the Paddle, like a flute, but with a lower pitch. They make a more natural flute-like sound upon returning. The multiplier upgrades to x50. EXTRA comes next.

In SUPER, the HUD is overcome by a scrolling gradient of darker, more saturated rainbow colors. The Beats now make a tinny, electronic string sound when hit, and a soft chirp-like beeping sound when they return. The multiplier changes to x20 here. MODE-Up to get to ULTRA, or Down to get to MEGA.

Play well enough in HYPER to MODE-Up to MEGA. The HUD changes to a randomized cycle of pale, pastel rainbow colors, Paddle included. The score multiplier is upgraded to x10 here. Every Beat makes a deep, echoing banjo sound upon hitting the Paddle, and a distinct, airy sound upon hitting the far wall after being rebounded. MODE-Up into SUPER or MODE-Down into HYPER.

This is the starting mode. The HUD is a bright magenta color, Paddle included. The text on-screen has a gentle gradient to a darker shade of magenta. The score multiplier is x1. Hitting a beat will make a softer, gentler chiptune noise in comparison to previous games' HYPER sounds. Perform well to MODE-Up to MEGA, or MODE-Down to NETHER if you play poorly.


The RESET visual seen when you MODE-Down in NETHER.
This is the last mode, giving you a chance to get back into HYPER. There is no musical audio in this MODE. The sound of hitting Beats is the same as in BEAT, though it's a fair bit softer and less sharp, additionally, Bonus Beats make a chirping sound, the very same that played upon collecting Golds in Runner's Retro Challenges. The interface is completely in black & white, though the backgrounds of the stages are still visible in monochrome. There is no score displayed, and the MODE has a multiplier of x0, meaning no points can be earned while in this MODE. Achieving a MODE-Up will return you to HYPER, but, in a first for the series, achieving a MODE-Down here does not restart the entire stage, but merely the current section, returning you to HYPER in the process. Your score at the start of the section is retained, you only lose your MODE and multipliers.

CUTSCENES[]
CommanderVideo embarks his third and final mission of his BIT.TRIP, "TO RETURN"
LEVELS[]

EPIPHANY[]
The first level of the game unlocks Perception once it is beaten. The backgrounds of this level, represent FATE. The modes up to GIGA show a track that must be followed.
PERCEPTION[]

The second level of the game unlocks Catharsis once beaten, CommanderVideo is now able to see the world from the outside, he finally sees his Growth from the beginning, MODEING up will descend you in deeper and deeper layers of the cube, and in Meta, you see an egg cell dividing. (Not present in any ports)

CATHARSIS[]
With the last level of the game, CommanderVideo is finally returning home. He sees the first level of BEAT, Transition, from a new perspective.
BOSSES[]
BREAKOUT VS[]

The boss in Epiphany is like a mash-up of Breakout and Pong, except you are trying to break through the opponent's wall and hit the rectangle in the back of the wall to win, as you have your own. If your side gets hit, then it counts as missing a beat, and you may mode down. However, hitting the opponent's side acts vice-versa. If the opponent breaks your goal, then you instantly hit RESET Mode, and restart the boss in HYPER, losing all multipliers and combos.
- This boss represents the anger CommanderVideo had, which lead to his downfall. After beating the boss, it represents that CommanderVideo has moved on to continue his quest to enlightenment.
Worth noting is the fact that the Steam version of the game possesses a common bug that causes this boss to become impossible to complete, as the opponent paddle will never miss.
OBSTACLE COURSE[]

The boss in Perception is an obstacle course where you must dodge all of the circles that come your way. In the middle of the level, the opponent appears and increases size, hiding circles about to hit you. This happens a second time, just before the final wave. At the end, the opponent shrinks, and then flattens into nothing.
This boss represents his anger that drove him to his blindness. The only thing he can do at this point, is to trust his instincts.
EMPTY BREAKOUT[]

The final boss is the same paddle as the previous levels, but this time, it blocks the entire left side of the screen, mimicking the power-up "MULTIPLY". You must reflect the beat that comes to back you again and again to damage the opponent. At set intervals, the beat increases in speed. Once hit enough times, the opponent starts to fade away. After 15 (10 on PS4/Switch) consecutive hits, the boss dies. However, if you miss the beat, the boss heals to full health, and the process starts over. This boss could last forever, as the other bosses have a set objective to complete. Your score is still affected when fighting this boss, so it is possible to end up with a very high score once the level is completed.
- CommanderVideo has to break the wall anchoring him down to physical life.
Secrets and Easter Eggs[]
(SPOILERS AHEAD!!!)
Big Words[]
You can see semi-opaque words at the beginning of each Stage.
The words are shown in this order: Stage 8 to Stage 1.
- Epiphany: IS, NO, AFTER, ALL, IS, IN, FLUX, SIMPLY.
- Perception: IS, NO, DEATH, THERE, IS, NO, BEFORE, THERE.
- Catharsis: A, LESSON, IS, LEARNED, LIFE, IS, SIMPLY, THERE.
Once you put all these words together, it gives you the following text:
A lesson is learned. Life is simply. There is no death. There is no before. There is no after. All is in flux. Simply.
Level names[]
You can see that in those three levels the level names of the other games scroll by quickly and semi-opaque in reverse order; starting with Catharsis from Flux and ending with Transition from BEAT (Runner 2 & 3 & RERUNNER not included and only the names of the zones in RUNNER).
Binary, Morse and Braille code[]
There are binary digits that appear in the background in each level. 21 through Epiphany, Perception and Catharsis, accompanied by stretching beats, and 9 in Home which are seen at the start
- Epiphany: 101000101011001011110
- Perception: 010000100100000010010
- Catharsis: 110010100000100000010
- Home: 010010010
If you take the binary, reverse it, and translate it, you end up with the result "I AM HOME"
In the MULTIPLY part of Catharsis, there's morse code. If you read this in the order it hits the paddle, you get "..- ....- ----. ....- ----- ---.. .---- ....-". Once reversed, you get "-.... ----. ..--- ----- -.... .---- -.... -..", which can be decoded into 6920616D, which can be further decoded from hexadecimal to get the words "I AM"
At the end of Catharsis is a sequence of beats which resemble braille. It currently remains untranslated.
These codes were placed into the game by Danny Johnson, who is the only person to know what the as of yet untranslated codes mean
Others[]
- In HOME, if the player keeps moving the controller long enough past the white screen an assortment of beats can be heard[1]
- In Catharsis, you can see some sort of lantern asteroid lighting up an invisible remixed arecibo message (e.g., instead of a man, there is a CommanderVideo silhouette with a larger head). It also happens to appear colored in Transition.
- In the ending level, the constellations appearing represent the star signs, like Taurus, Sagittarius, etc. but sometimes cut or realigned at some points.
- In Epiphany, if you're in the Super Mode, the sides of the BEAT in the background resemble the striped squares shot out of the VOID in Ultra Mode.
- In Ultra, the sides of the line show a double-helix pattern, which could represent CommanderVideo's genetic information.
- In Perception, a Beat pattern appears regularly that strangely resembles the Coda of Wolfang Amadeus Mozart's Piano Sonata No. 7 in C major, more specifically, the sixteenth notes of the third and fourth measure. In fact, only one note represented by a Beat is pitched a musical second higher than the patterns in the Coda, every note pitch and spacing matches perfectly otherwise, though this might only be a coincidence.
Trivia[]
- When you complete a level, the background of the menu changes to the HYPER background of the unlocked level.
- However, after completing Catharsis, the background changes to the planet from the ending level.
- The Steam version is currently delisted[2], the only way PC players can officially play FLUX is either purchase the game on GOG[3] or the The BIT.TRIP Collection.
- unofficially you can play FLUX via emulation.
