Playable Halo 2 E3 2003 demo released In a joint effort with Halo Studios and marking Halo 2's 20th anniversary, Digsite has released a playable restoration of the game's E3 2003 demo, for MCC PC. Not sure how off-script you can go to tackle things in different ways, but multiple playthroughs are already up on YouTube, such as the one below, and the mod includes a 'Playground' version of the level which allows free roaming of the city. There's also co-op support. All in all, seems like an impressive job and a must-have for any Halo 2 fan! Thanks, MangoOfDoom.
