Imagine the original NES Super Mario Bros.
Now imagine that you can play that game with Mega Man, Samus (Metroid), Simon (Castlevania), Ryu (Ninja Gaiden), Link (Zelda), Bill (Contra) or Mario… if you’re boring like that.
Imagine no more.
This is Super Mario Bros. Crossover, a free Flash game played in your web browser.
The game plays exactly like the original Mario. Same layout, enemies, and graphics, and a more interesting character selection.
They will be adding SOPHIA THE 3RD, the tank from Blaster Master sometime this month.
You’re going to want to set up a game pad for this one.
