Sonic Ancient Isles

Sonic Ancient Isles

What if the events of Sonic 1 happened on a different island entirely? This hack has entirely new levels, sprites, and music for you to enjoy.
Sonic Streets Of Rage 3

Sonic Streets Of Rage 3

An excellent beat 'em up from the heyday of side scrolling is Sonic Streets of Rage 3. Axel and Blaze, two longtime Streets of Rage favorites, are among the four characters you can select. The main treat, though, is getting to play as Sonic in this fantastic game. Be aware that you can perform a wide variety of attack combos. For instance, the moves made by B + down, B and right, right, B differ from one another.

An epic classic from the heyday of SNES retro gaming. A title with no introduction necessary.

Shadow Xs

Shadow must climb vertically to find the exit door at the top of the level. Grab rings along the way to score points.
Sonic Advance 2
