How to make maps for GTA Halo
This first image shows you an Original aerial view of Los Santos. The red lines mark out the boundaries of where the Halo content base must go. Everything above can cross over, over lap, go under ground its your imagination, however, just make sure you dont Block the roads. You can make tunnels, canyons over the roads but we dont actually want to block them. This is so that the original crash free main.scm can remain intact.
By following the instructions you can totally change the scene without messing up the roads
Original Sewers/Tunnels must also be left in tact. The photos below show you how I created my map around the sewers.
Now with my Halo touches I’ve turned it into a totally different scene.
