10 Embarrassing Accidental Video Game Leaks
4. Ultimate Marvel Vs. Capcom 3
In 2011, Capcom officially announced during San Diego Comic Con that they would be releasing Ultimate Marvel vs. Capcom 3 in November that year. As is often the case with fighting games, only a few characters were announced, with the remainder of the roster planned to trickle through up until the game's release date to keep the fires of hype stoked.
Twelve characters were reported to feature in the game, however Capcom only released details on 4 of them - Hawkeye, Ghost Rider, Firebrand, and Strider. However, people noticed that the images linked to Capcom's server with the character's name in the extension, and figured out through a series of guesses that they could access the unreleased characters through their concept art.
The NeoGAF community managed to unearth evidence of Dr. Strange, Nova, Rocket Raccoon, Iron Fist, Phoenix Wright, Frank West, Nemesis, and Vergil, officially unveiling the entire roster.
Capcom acknowledged the authenticity, but decided to drip-feed us the unreleased characters anyway.
