This page details one or more prototype versions of Sonic the Hedgehog 4 - Episode I.

Sonic the Hedgehog 4 - Episode I had... an interesting development cycle, to say the least. Three prototypes are known to exist (although one, a PS3 "Sony QA" build, is yet to be released publicly), all seemingly coming from the same timeframe.

 PartnerNET Prototype
Xbox 360 build dated February 9, 2010, notable for causing such extreme fan backlash that the game's release was delayed to fix the cited issues.

 Japanese WiiWare Prototype
Wii build also dated February 9, 2010, which had accidentally been published on the game's release date.

General

  • All three prototypes bear strong resemblances to the iOS/Android version. They contain the two controversial "gimmick" levels, less-polished physics, and simpler Stage Select screen that were replaced in most releases.
