Sega having trouble with Sonic? It’s been that way for years. A long time ago on console named after a planet in this galaxy, Sega was developing Sonic X-Treme which had a unique concept of rounded worlds. The result was a game that looks like a mix of Sonic 3D Blast and the PsOne game Pandemonium that we never got to play it since Sega canned Sonic X-Treme.
Most of the revealed Sonic X-Treme footage has shown Sonic jumping outdoors like a platformer. A new Sonic X-Treme video discovered by a LostLevels forum member has more of a Sonic feel to it. In this level Sonic rolls on windy tracks while the whole world spins around him. The effect is neat to watch and it may have been neat to play if Sonic X-Treme materialized.
