It's the same post-apocalyptic world and Chris, the mysterious bounty hunter better known as Iron Girl, is still the deadliest fighter on the planet. Unfortunately, she also still has no memory of who she is or where she came from, and, in a land where knowledge is power, that means her days could be numbered. Everything may be about to change, however, if she can acquire a priceless memory-retrieving device called The Storage. But to get it, Iron Girl will have to save a colony and take on both an army of assassins and a renegade group of bandit militia called Sparti United. It's a sequel that's far more than an equal, with more daring stunts, more explosions and more Iron Girl action than ever before as fist, feet, and other body parts go flying in IRON GIRL: ULTIMATE WEAPON!
