Because of the recent addition to Forge in which we can add all REQ weapons and vehicles, the custom game options are lacking. Currently, you cannot select certain variations of weapons (like kinetic bolt AR or recon SMG) or golf clubs. Could it be possible this is updated in the future to where we can select specific variations and add the special types of weapons such as golf clubs?
On a side note, the addition to limit certain types of vehicles from spawning in the map could be added. Instead of all vehicles not spawning, maybe add the option to have land vehicles or air vehicles being limited from spawning. Maybe add the option to also limit the type of weapons being allowed to spawn as well- be it UNSC, Covenant, or even REQ or variations of weapons.
