This page details one or more prototype versions of Sonic the Hedgehog 4 - Episode II (Windows).

Beta 8 of Sonic the Hedgehog 4 - Episode II was a build of PC version accidentally leaked by Sega on April 21, 2012. The build was playable because of a security hole allowing people who pre-ordered the game on Steam to play it early. The bug was fixed the next day by adding a message stating the player should buy the game first, and was irreversible without using a cracked build.

Despite this, Sega didn't take down the accounts who played the game early as they stated the accounts downloaded the game legally, and it was their mistake.

Because of its release date, the build is very similar to the final, with only minor changes made.


  • Sylvania Castle Zone's textures often fail to load.
  • The game crashes upon switching windows if run in full-screen mode for some people.
  • Pressing 0 (LT using an X360 controller) will give the player 99 rings.
  • Playing the game in the higher resolutions will cause lighting effects to disappear.
