For a regular slayer map you wouldn't change the spawns to a color unless it was a team slayer(it's also important to make initial spawn points)also spawn stuff in forge
you can allow your halo reach map to be playable to slayer and only one other game type, but you have to designate that game mode where it says "basic editing"just before you start the forge game. make the area however you want, then save it as a new map. quit and you should be able to play that map using the designated game type.
make sure they are really, really good, get noticed by BUNGIE, and if they like the map they will put it in the next update.
Go to forge and make a map and then you go to the menu and slecte add map in halo Reach
Play team slayer and get it as a map choice.
if you are saying how do you make your own world in halo reach, use forge mode to make a map.
Just make a normal forge map then seclet juggernaut
Slayer DMR's on Countdown or SWAT on Powerhouse it's the best maps and game types around.
you can't make a firefight map using forge, only mutiplayer
i am VERY sorry to inform you of this, but you cant. in halo 3, halo reach, and halo 3: complete multiplayer experience you can.
it depends like if you are just building a map forge world hands down but for somthing like infection maps go for the cage,or for slayer,a map I made called Frigate Deploy.And for an invasion map,go for island
You cannot make your own maps in Halo: ODST, it doesn't contain forge world. Halo 3, Halo: Reach and Halo 4 all contain forge world.
maybe
