A rumored interactive follow-up to the epic final third (or was it fourth, Salma?) chapter of Robert Rodriguez's El Mariachi action series. Rodriguez mentioned his intents to release a PSP game based on the film at a comic book convention - the game would be a side-story from the film series and would follow Johnny Depp's blinded, corrupt Agent Sands.
This game was unfortunately not known to have reached any level of development, and has not been spoken of since. Alas, this game is not expected to ever be released.
