Play Jim Power – Mutant Planet (Beta) Online

Jim Power – Mutant Planet for the Sega Genesis was an unreleased beta, developed by Loriciel and intended for publication by Electro Brain. It arrived during a period when the Genesis was saturated with action platformers, many attempting to blend sci-fi themes with the run-and-gun mechanics popularized by more established franchises. This particular version never saw a commercial cartridge release, existing only as a prototype that circulated among collectors.

You control Jim Power, a space marine tasked with rescuing scientists across a hostile alien world. The game progresses screen by screen, requiring you to jump across precarious platforms while fending off waves of mutants with a rapid-fire blaster. A key mechanic involves collecting power-ups that change your weapon's firing pattern, from spread shots to lasers, which are essential for dealing with the game's large, screen-filling bosses. The pacing is relentless and the collision detection can be unforgiving, making even basic navigation a tense affair. It feels like a rough, unpolished challenge where every new area demands quick reflexes and a lot of patience.
