Q: What is ElDewrito?
A: Two days after the initial announcement of Halo Online, an early build of Halo Online was leaked from the official website. This build differs from the official game in that it contains Forge mode, Halo 3's menus, and various Halo 3 assets (though not Campaign or Theater). ElDewrito is a mod which makes Halo Online playable for all, and includes changes and additions such as English menus and HUD, support for medal/announcer packs, a server browser, and more. Its name is a play on the name of Halo Online's original executable, eldorado.exe.
