Edge Of Elysium

I've tried this a thousand different ways but to no avail. I understand this is HOW it's suppose to be done, but you cannot do it this way. I REALLY need SOMEONE to boot up Halo 2 Anniversary and ACTUALLY create a territories gametype on Skyward This HAS to be a glitch because you CANNOT create a custom game for ANYTHING other than Slayer, Juggernaut, or Infection...

This doesn't seem to be working. There are no "Save This Gametype" options both after selecting territories in Forge Editor nor during the build. Now if you go to a different map you can choose to save a tweaked gametype there however there doesn't seem to be anyway to create a Territories Gametype in Skyward.....can someone please confirm this or try a different route?

Is there a way to create a custom Territories game to be used in Skyward? It only allows Slayer, Juggernaut, and Infection????

Is it possible to spawn/despawn respawn points like a checkpoint system? I would like to start with a singular spawn point, and at a specific area with an on-enter trigger, despawn the intial point and spawn a new respawn point there....anyone know how to do this? The triggering doesn't seem to be affecting the spawn points, only objects....
