Remember the fan-made Super Mario first-person shooter from developer Sean Noonan? Back then, it was just a mere technical concept that he shared for fun – until today!

To celebrate MAR10 Day, Noonan released his fan project (titled ‘The Super 1-1 Challenge’) for free to the public. As we reported previously, the game sees the whole of World 1-1 from Super Mario Bros. re-imagined as a 3D FPS game – where Mario uses a plunger gun to take out Goombas!

You can check out a new trailer for the fan project below, or try it out over here.
