Sonic Robo Blast 2 is a free, open-source three-dimensional platform game inspired by classic Sonic the Hedgehog titles. Built using a modified version of the Doom Legacy engine, it recreates the speed and platforming mechanics of traditional Sonic games in fully explorable 3D environments. Players can control Sonic, Tails, and Knuckles, each with distinct movement abilities. Its single-player campaign includes interconnected levels, collectibles, enemies, and boss encounters. The game also features cooperative play, competitive racing, and multiplayer battle modes. Players can unlock additional content, collect Chaos Emeralds, and compete for high scores. Extensive modding support allows the community to create custom levels, characters, and gameplay mechanics.
