Please be advised that Forge Island , the new Forge mode usable environment of Halo 4 , is now available for download from Xbox Live; the content is free and takes up 154 MB on your media ( link Xbox.com ). Forge Island is a broader environment for creating user levels: consists of three different islands and comes to meet those that were hoping for a return of Forge World in the game. Here we propose a demonstration from the PAX in which had been shown the characteristics of the new expansion.
