Sonic Robo Blast 2

It is a 3D fan‑made game that recreates the feel of the classic Sonic the Hedgehog titles using a modified Doom Legacy engine. The project provides a playable experience with many levels, enemies, and high‑speed platforming that mirrors the original Genesis games, though development is ongoing and the game is not yet feature‑complete.

The software targets players who enjoy Sonic‑style platformers and want an open‑source, community‑driven version that runs on macOS. It also appeals to developers and modders who wish to contribute to or extend a game built on a well‑known engine port.

Distinctively, the game leverages the Doom Legacy port to render 3D environments while preserving Sonic’s signature mechanics, and it maintains a public development roadmap with regular patch releases and community resources such as forums, Discord, and a master server.
