In the Starcraft 2 map editor is it possible to control two different players?

Yes, in the Starcraft II map editor, you can control two different players by creating multiple player slots and assigning them to different teams. You can set up triggers to switch control between players, allowing you to manage both simultaneously during gameplay. However, this typically requires careful planning and scripting to ensure a smooth experience. Keep in mind that in multiplayer games, each player usually controls their own units, but for custom maps or scenariOS, this feature can be utilized effectively.
