NETHER is an abysmal mode in the BIT.TRIP series, first introduced in BIT.TRIP BEAT, along with HYPER and MEGA. In every level, NETHER is the worst mode and gives not points, any cutscenes, not any colour. When in this mode, the sound effect for any successful action is an old style beep. Regardless of the sounds, none are heard when you make an unsuccessful action. In CORE, the sound of the rhythm can be heard and when you collect rainbow BEATS, the sound of the transition phase can be heard on the Wii Remote.
HUD effects Edit
In BEAT, the HUD is black and white. “NETHER” is not shown in the background.
CORE's NETHER is similar to the one in BEAT, except the screen fades out when you fail to hit 16 BEATS.
VOID has a rather minimalist take on NETHER. The background is just a greyscale static TV screen; when passing a checkpoint, you lose 50,000 points.
RUNNER did not have NETHER mode, but the bonus level can be acted as NETHER.
The HUD here is grey and gun metal all around with a static backdrop added.
In FLUX, the HUD is white.
