Mario entering Contra World
July 4th, 2009 
Yes, you will see Mario entering the Contra world in the video. It is from a big crossover fangame called Mushroom Kingdom Fusion, which pits Mario, Luigi, Sonic, and other characters in different game worlds. It shows off a Contra-themed level in a future version of the game called The Energy Zone. It is made by MKF development team member Obreck2. Video after the break.

Whoa! Very classic indeed, the game we all grew up with except for this version or it’s just me who saw it the first time?
I like the fact that Mario can jump over an opponent while striking the others, cool! Oh well, it’s not as spectacular as the current online games like World of Warcraft but back then, Mario rules the gaming industry.
