Unteralterbach (often stylized as Unteralfterbach or mis-transcribed as Unteralbach) is a German adult adventure game known for its retro pixel art, dry humor, and non-linear exploration. The number "21" refers to a specific street address within the game’s world.

In the game's geography, Unteralterbach is a fictional small town in Bavaria. Unteralterbach 21 is typically one of the following (depending on which fan patch you are using):

On Day 5, a character asks you to spell "Unteralterbach" in Morse code. The correct sequence mimicking a keyboard is: Ü = U with diaeresis -> The game accepts UE as a substitute. Type UNTERALTERBACH in all caps. If you miss a single letter, you get the joke "Bad End."

Honestly? Yes. But only if you stop trying to "win."

Unteraltenbach 21 is a commentary on nostalgia as a trap. The ending (Ending E: The Return) is impossible to trigger unless you close the game during the credits sequence and delete the save file manually from your folder.

If you are looking for a guide because you are frustrated, my best advice is this: Stop trying to solve the puzzles and start listening to the silence.

And whatever you do, don't look up at the water tower on your 21st loop.
