The question shouldn’t be, “what would you do if you had superpowers,” it should be, “what would you do if EVERYBODY had superpowers?” In the late 1800’s electricity began to revolutionize our world. Lights, motors, generators, appliances, things that those who originally brough us electricity couldn’t even have concieved of. In one alternate world, though, the high-voltage lines brought us another kind of power entirely. The year is 2004, and everyone in the world has superpowers. And while our world has not fallen apart, things are certainly... different. From housewives with super-strength to flying businessmen, from magnetically-powered cops to titanium-skinned criminals, the world is a bigger and more aweinspiring place than ever. Come take a look at how it happened, and what parts you can play in this larger-than-life setting. From pedestrian-level adventures to cosmic sieges of reality, there’s always something interesting going on. Mutatis Mutandis is an M&M Superlink supplement which introduces a whole campaign setting for superhero roleplaying, a few new feats and powers, NPCs to help you flesh out the world, and of course, adventure ideas for when your players ask, "Everyone has powers? What the heck do we do?"
