This article pertains to the beta elements from Sonic & Knuckles.

The True Doomsday Act 2

The actual Act 2 of The Doomsday Zone is inaccessible by normal means unless a glitch is used. The level is empty, except for a few chunks off screen. Due to there being no Rings in this area, the player will die.

Tails

Tails in S&K

By hacking the game, a savestate can be found of a file for Tails and he can be enabled by using a PAR code of FFFF09:02. While he is playable, almost all his sprites are missing. The only sprites that are available are Tails running around the collapsing pillar at the end of Sky Sanctuary Zone, along with Lave Reef Zone with the same context, and his transformation sprite.

Super Insta-Shield

At one point in development, Super Sonic was supposed to have his own Insta-Shield which was superior to its predecessor. This Insta-Shield would be activated the same way as the Insta-Shield, except once activated, it would release a golden wave of energy instead of white that had a greater range and would last a whole second before having to recharge for about two seconds. This was removed because if it is used, the game will freeze for about three minutes and for some unknown reason, send Sonic to Hidden Palace Zone where the game would subsequently crash. (The move was found in the sprite files)
