Hello, I am planning a series of non-profit videos (one for each halo multiplayer maps) of me just walking through each map and looking at the design and weapons/placement etc. You can use them as references for creating your forge remakes without having to boot up the game yourself 
You will be able to find all the videos HERE as I upload them over the coming weeks.
Once again feel free to use these as references for your forge maps, I tried to look at every single nook and cranny of each map for accurate representation. This is not advertising as it is non-profit.
