Sonic the Hedgehog CD (Jun 21, 1993 prototype)

What is Sonic the Hedgehog CD (Jun 21, 1993 prototype)?

Sonic the Hedgehog CD (Jun 21, 1993 prototype) is an early developmental version of the iconic Sega CD platformer, predating the final 1993 release. This prototype showcases unfinished mechanics, placeholder graphics, and experimental design choices, offering a glimpse into the game's evolution. Notable differences include simplified level layouts, unused music tracks, and unpolished time-travel mechanics that would later define the final version. Discovered in hidden archives, this build highlights Sega's iterative development process during the 16-bit era.

Game Features

• Time-Travel Mechanics: Early implementation of shifting between past and future versions of levels, though less refined than the final game.
• Retro-Futuristic Level Design: Features placeholder art assets and simplified versions of iconic zones like Palmtree Panic and Stardust Speedway.
• Proto-Soundtrack: Includes unfinished MIDI tracks and sound effects, some of which were reworked for the final release.
• Hidden Content: Early versions of the game's "Little Planet" hub world and unreleased boss encounters.
• Sega CD Optimization: Demonstrates early experiments with the console's CD-ROM capabilities, including streaming audio and animated cutscenes.

How to Play Sonic the Hedgehog CD (Jun 21, 1993 prototype)?

As a Sega CD platformer, controls are optimized for arcade-style precision:

1. Movement: Use arrow keys or WASD to run, jump, and navigate levels.
2. Jump/Spin Attack: Press Space or Z to jump; hold the key to perform a spindash in midair.
3. Action/Confirm: Use X or C to interact with objects, activate switches, or confirm menu selections.
4. Time Travel: Early mechanics require collecting two monitors to trigger past/future transitions (interface and execution differ from the final game).
5. Camera Control: Tilt the virtual camera using Shift + Arrow Keys to reveal hidden paths (a feature later automated in the final version).

No. Only early versions of Palmtree Panic, Stardust Speedway, and a proto-form of the Little Planet exist, with simplified layouts and placeholder textures.

Can you access the Time Eater boss in this prototype?
The Time Eater appears in a rudimentary form during testing, but its attack patterns and visual design are incomplete compared to the final game.
