Pixel Force: Head 2 Head was a PC fighting fangame, set to contain 30 different characters from 10 games. It was created by Eric Ruth, an indie developer best known for making 8-bit demakes of games like Halo, DJ Hero, and Left 4 Dead.
On February 14, 2011, a single trailer for the game was posted under the "Machinima" YouTube account. It showcased a seemingly functional game engine and even a few characters, such as Ryu (Street Fighter), Wolverine (Marvel vs. Capcom), Captain Commando (Marvel vs. Capcom), Terry Bogard (Fatal Fury/King of Fighters), Scorpion (Mortal Kombat), Orchid (Killer Instinct), Charlotte (Samurai Shodown/Spirits), and Sol Badguy (Guilty Gear). Since the trailer's release, no new information has been surfaced on the game, and it isn't even listed on Eric Ruth's website.
According to Eric Ruth in a private skype chat, the game was never finished as "It was too buggy" and he "couldn't get online working properly." However, the soundtrack itself was finished and can be found at https://dl.dropboxusercontent.com/u/71895074/H2H_OST.zip
