Pixel Force: Head 2 Head (partially found fighting game; 2011)
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 (a remake of a game for an older platform) of games like Halo, DJ Hero, and Left 4 Dead.
On February 14th, 2011, a single trailer for the game was posted on 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 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.
