How to make Maps Game modes?

How do I make a game mode for a map?

So if i have a level how can I make multiple copies of that level but all with different game modes that you can play?

Example Team death match, Death match, Survival, Free roam, Racing ect.

Hi Brian,

following this documentation you can use ?game= suffix when loading a map to override the default GameMode to use like /Game/Maps/MyMap?game=MyGameMode.
