This is a Mod for the Sega Mega Drive/Genesis, released in 2009. It presents a collection of zones that were originally cut from the development of its parent game, Sonic the Hedgehog 2. The gameplay centers on navigating these previously unreleased stages, offering players the chance to experience environments that were conceptualized but never officially implemented in the original title.

The core experience involves the familiar 2D platforming mechanics of running and jumping through diverse environments. The primary appeal lies in exploring these "lost worlds," which have been recreated using a combination of elements from early prototypes and designs based on historical development information.

What is the core gameplay loop?

Players engage in fast-paced platforming challenges across a variety of stages. The gameplay loop involves moving through each zone, overcoming obstacles, and reaching the end, all within the context of environments that were not part of the original release. The focus is on delivering a complete playable adventure composed entirely of these cut content stages.

Exploring Cut Content

The most distinctive aspect of this game is its exclusive focus on zones that were removed during the development of its predecessor. These stages have been brought to life through different methods: some were adapted from the Sonic 2 Simon Wai prototype, while others were constructed based on magazine pictures and interviews with original development staff. This provides players with a unique opportunity to interact with content that was never officially released.

How were these lost worlds recreated?

The recreation process involved adapting existing prototype data for some zones, directly porting them from the Sonic 2 Simon Wai prototype. For other zones, new designs were created, drawing inspiration from magazine articles and interviews with individuals who worked on the original Sonic 2. This dual approach aimed to faithfully represent the intended designs of the cut content.
