(sega mega drive & genesis classics 42/58)

Like Gunstar Heroes on speed, and it's truly remarkable. There's absolutely no breathing room, and it throws bosses at you constantly, but the easier mode has a few things to make it more manageable such as a slowdown feature and unlimited continues. It's insanely fucking cool, but honest to god gave me sensory overload. If you want the most absurdly paced shit out there then this is for you.
