All of these maps can be found in my bookmarks. My gamertag is Wally17. Enjoy!
This is a compilation video I put together showing all of the maps I discovered how to get out of and canvases on each for forging. Rather than make an individual video for each map, I decided to make this. Some maps, like Fathom and The Rig, I just threw down a floor or two, but the Forging space is quite large. While others, such as Truth and Eden, I maxed out floors and got as close as possible to kill barriers.
I made all of these canvases with the Halo community in mind, especially the one here at ForgeHub. There are some great forgers here and I'm excited to see what cool map creations they can come up with!
Edit: With the new release of Riptide, I have added that to the other out of map canvases in my bookmarks, and there is a videoon my YouTube channel.
UPDATE:
Part 2 of this compilation adds more maps. They are in my bookmarks. Enjoy!
