Sonic the Hedgehog 3D(Sonic 3D) is a 3D platformer and reboot of the Sonic the Hedgehog series. The game notably excludes all other Sonic character mainstays besides Sonic the Hedgehog and Doctor Ivo Robotnik, featuring gameplay similar to the Sonic and Shadow levels of Sonic Adventure 2. The game was released for the Wii U in 2014 and was developed by Unversed Entertainment rather than Sonic Team.


Sonic 3D is a 3D platformer using physics and speed together to create a unique and fun experience. Players jump around and use various abilities to make it through levels. Spin-Dashes go fast and destroy those in their way, but are uncontrollable, grinding will allow you to go on rails, Sonic can also push things to solve puzzles, and jump onto switches. Sonic will also find various items to give him new powers across the game to allow him to do different missions. Players clear 3 act zones and then fight a boss battle, as well as missions and minigames that are optional. Completing these earn Red Rings, and when enough Red Rings are collected from stages and missions, Chaos Emeralds are unlocked. When all 7 are earned, the final zone is unlocked and after collecting 50 rings, Sonic can transform in levels. Players access Zones and Missions through a network of caves in South Island in 2D.


The story is a simple one. On South Island, animals have been stolen from their home and used by Doctor Ivo Robotnik as an army of robots to take over the world. Sonic the Hedgehog, a hero always on the move hears of this and heads out to stop Robotnik.
