Level select

Level select, also known as "Zone Select" for Sonic games since the levels aren't called levels, but zones, is a menu from which you are able to access any level in the game, as well as:

• Special stages
• Bonus stage (in Sonic 3 & Knuckles only)
• 2-player levels (in Sonic 3 only)
• Sound test

Games which feature a Level Select menu

• Sonic the Hedgehog
• Sonic the Hedgehog 2
• Sonic the Hedgehog 3
• Sonic & Knuckles
• Sonic the Hedgehog 2 (Game Gear)
• Sonic Chaos
• Sonic Triple Trouble
• Knuckles' Chaotix (accessible through modifying colour bars in the 'colour test' screen)

This option allows you to search through (usually) a menu with a listing of different levels in a game then lets you choose whichever level you wish to play. Another very useful feature for debugging/development.

In Sonic 3, entering a level from the level select screen will enable the reset/slow-motion/frame advance cheat. This will not, however, enable object placement or gravity reversal which require debug mode to be activated.
