Sonic ERaZor 8 – Unterhub Place

The full Unterhub Place saga from Sonic ERaZor 8, featuring the sneaky Rollerbot stealing my freaking spike trophy. He's gonna pay!

This entire sequence is a visualization of what Spring Yard Zone and ESPECIALLY the Egg Stinger boss in act 3 felt like when I was seven years old. The trauma caused from that boss doesn't get talked about enough, in my humble opinion. And it was also an excuse to get revenge against the most annoying badnik in all of Sonic 1!

What is Sonic ERaZor?

Sonic ERaZor is a completed ROM hack of Sonic the Hedgehog created by Selbi (me), with extensive technical assistance by vladikcomper. This hack is unlike many others, featuring a (bizarre) in-game story line and ridiculous challenges/mechanics, as well a ton of cutscenes, story screens, and easter eggs. Furthermore, while not originally intended as such, the hack is often summarized as "What if Michael Bay directed Sonic 1?" due to its rampant use of explosions and focus on action.

The name ERaZor, with its upper- and lowercase letters, is a mix of the word eraser and the German word Scherz (meaning "joke" in English). Despite the naming similarities, it has nothing to do with Erazor Djinn or Sonic Eraser.

When first released back in early 2010, this hack had no goal whatsoever, and any ideas just went in. Today's releases have a lot more structure and thought-out gameplay elements. The difficulty has been steadily balanced with each new release, mostly due to negative feedback regarding the frustrating game design of the earlier ones. However, it deliberately remains tough and has never abandoned its roots as a difficult game.

In 2024, the hack received its first update in over eight years with the release of the Seventh Public Release, which introduced Casual/Frantic Mode (a unique difficulty selection specifically built around ERaZor's identity). Four months later, in early 2025, a huge patch in the form of the eighth public release followed, introducing 16:9 widescreen support (for RetroArch with the Genesis Plus GX Wide core).
