Can't wait for the forge update to drop! As soon as it does i'm going to be forging invasion. Honestly can't wait for this. Decided I would live stream while I do it to try and build some hype around forge. Made a quick announcement video. https://www.reddit.com/r/halo/comments/3wgbp8/forging_invasion_on_halo_5_guardians/
As some of the other commenters already mentioned obviously we can't have a 100% faithful reproduction but I think with scripting and the amazing forge pallet we have many great things can easily be accomplished. Eager to see your work.
