Just use king of the hill and set the hills as the checkpoint then make it so it won't dissappear after a player grabs it but until, all do.
In Halo 4 I've found that the gametype "Flood" gives a pretty good amount of credits (Somewhere around 2k) per game. I believe the "Grifball" gametype gives 3k.
because your probably on basic editing change the gametype to whater gametype the map is for then all the laybls will be there
go to match making pick a gametype and start
on the halo 3 main menu go on matchmaking pick a gametype and select start match making
Maybe in the future, but not yet.

On the custom games menu, highlight the game type and press X to edit You can customize all game type
In the gametype editor, go to player/spartan traits, loadouts, and in the weapons section select bottomless clip for unlimited ammo.
You have to download the modded custom gametype known as carbine. Due to it being modded, this is the only available substitute.
Head into custom games and select the gametype you would like to use. Then go into game options and edit the game the way you would like it. Once you are finished, press X to save and name your gamemode.
