This page details one or more prototype versions of Guitar Hero.
The September 3, 2005 prototype build of Guitar Hero was leaked as part of Project Deluge, released through Hidden Palace's website and archive.org on March 20, 2021. Nothing was known about this build prior to its release, although other beta versions of this game had been seen in marketing material before.
- The HOPO threshold in this version of the game is stricter than retail; 159 ticks (1 tick less than a 12th note), vs 170 in retail. Charts where this adjustment is particularly easy to spot are You Got Another Thing Comin and Texas Flood on Expert.
- Notes that follow a chord and have the same color as the chord's lower fret can be HOPOs in this build, unlike retail where they are always strums. A good example of this is Heart Full Of Black on Expert's orange strumming section.
- Whammy rate is different in proto build, gives you less Star Power.
- The bug in retail where the 2nd note of the song always appears as a strum, even if it is a HOPO, is NOT in the prototype.
The setlist in the prototype is almost the same as in the final game, with one ordering difference and a few naming differences.
