Play Portal Gun in Sonic 2 Online

Summary

Portal Gun in Sonic 2 is a fan‑made modification that drops the iconic Portal gun straight into the classic Sonic the Hedgehog 2 world. The tweak reshapes Sonic’s sprites just enough to make the gun feel at home while keeping the original speed‑centric feel. When you fire, paired portals appear and instantly transport you to the matching exit, turning loops and gaps into quick shortcuts. The portals aren’t just for travel – they also snag enemies and even bosses, letting you reposition threats or set up chain reactions. It’s a quirky mash‑up that lets the fast‑paced platforming meet the mind‑bending mechanics of Portal, all on the Sega Genesis engine.
