About this game

Eggman's off on vacation, Ring Racing, so Tenna came out of Eggman's TV and took everything while he was gone.

Blast through Sonic 3 with a Deltarune twist! With over 18 completely new bosses to fight, 6 new gameplay gimmicks to endure, and a modified story, Sonic 3 & Tenna completely transforms the game into a new, yet familiar experience! Not a Undertale, Deltarune or UTDR fan-content fan? That's okay! The bosses have been designed with Sonic gameplay philosophy in mind, and the entire experience itself is stand-out enough to not require any prior UTDR knowledge.
