Sonic 2 Retro Remix﻿ is a fan-made hack of Sonic Sonic the Hedgehog video game that incorporates exploration.
It means progressing from one level to the next by collecting and searching for Chaos Emeralds to unlock new levels.
Do boss battles, speed runs and score attacks.
You must learn each level?s ins and outs, instead of just finding the easiest way to the goal. Enjoy in Kiz10 !
