Copy and pasted from my post to Reddit.
I'd like to start out by saying this map was one of my favorites from Halo 3 and holds a special place in my heart. That is why when forge become available I immediately went to work on this classic map. I spent over 40 hours on this work (longer than I'd like to admit) and spent hours tirelessly measuring and scaling everything properly to work with Halo 5 mechanics. I poured over all the little details from the original, bringing this map back to Halo 5 with new aesthetics (as well as old ones) and really tried to push what the new Halo 5 forge engine was capable of doing.
EDIT: Added version 1.1 (included support for Flag and Strongholds)
EDIT 2: Added version 1.2 (includes updates to invisible blockers so you cant get out of the map. Credit to TCbite. Also included windows in sword room. Added fusion coils and pylons to map by green hall. Added crate in front of S1
EDIT 3: Added version 1.3 Added more invisible blocks to prevent people getting out of the map and some blocks were z fighting each other so i fixed those as well. Also added some sound effects to shotgun area and green hall
EDIT 4: Added version 1.4 Thanks to yoElements crazy jumping skills I managed to fix even more jumps to get out of the map.
