This is the coolest thing ever!!
I first saw a youtube video called Super Mario Bros. Crossover Trailer and didn’t reflect upon it actually being a game, just thought it was a cool video somebody put together. But NO! It’s actually a game! Where you can play as several famous 8-bit characters (such as Samus Aran, Mega Man, Link, etc) in the Super Mario Bros world!
Now go play Super Mario Bros. Crossover 2.0 here!
