Play Chip McCallahan in Sonic the Hedgehog 2 Online

Chip McCallahan in Sonic the Hedgehog 2 is a ROM hack for the Sega Genesis, released unofficially by fans. It takes the original Sonic 2 engine and replaces Sonic with a custom character, offering a fresh but familiar experience within the 16-bit platforming era.

You control Chip McCallahan, navigating through modified versions of Sonic 2's zones. The main goal remains to reach the end of each act and defeat Robotnik, but Chip handles differently; he slides with low traction and has a unique, floaty jump arc. You still collect rings, break monitors, and avoid enemies, though the altered physics demand adjusted timing for platforming and boss patterns. The pacing feels slightly off at first, especially if you're used to Sonic's responsiveness, but adapting to Chip's movement becomes part of the challenge. It's an odd but deliberate twist on a classic formula.
