This is by far, the best video game footage out there.
Not only is Marvel vs. Capcom 2 one of my favorite games ever, its also one of the most celebrated fighting games of all time.
In case you don't understand why and how the video above is so kick ass, here's why: Marvel vs Capcom 2 is a 3-on-3 fighting game meaning you use your three characters to KO the opponent's team also with three characters. At the start of this video, we see that one team is left only with one character. Now he has to fight a whole team of three characters and each of them has almost full life bars. To top it off, Magneto-Storm-Psylocke (known as MSP) is known to be one of the top tier teams in MvC2 and Cyclops is not really a top-tier character. Nevertheless, Cyclops managed to pull off a win.
This video is from Evo 2007. Its Justin Wong vs Yipes.
