Sonic 2 – Emerald Safari

Sonic 2 – Emerald Safari is an action-platformer mod of Sonic the Hedgehog 2 that changes how Chaos Emeralds are earned and how they affect gameplay. Each emerald now grants unique abilities that stack, allowing players to gain new powers before unlocking Super Sonic. You can play Sonic 2 – Emerald Safari quickly and easily for free on kbhgames.com, right in your browser with no installation needed.

Unlike the original setup, emeralds in this version can be collected not only through special stages but also by earning a continue at the end of each act. Each emerald adds a new advantage that builds on the last. The first provides an extra hit point before losing rings, the second lets players stay underwater for a longer time, and the third boosts acceleration speed. The fourth rewards double rings in normal stages, while the fifth extends that bonus to both normal and special stages. The sixth increases jump height, and the seventh completes the full set of upgrades leading up to Super Sonic.
