How to switch targets by changing the direction units face
Introduction
Use the Mobile Beacon to order a unit in the direction you want it to face.
Now cancel the Mobile Beacon and the unit will continue facing the desired direction.
You can repeat this process for other units. At the start of every deployment phase, units will reset and face the nearest enemy units and structures.
Why Change Direction?
Examples
In this scenario the Melting Point must first destroy the Level 2 Fortress to survive, but the Melting point faces the Level 1 Fortress by default because they are nearer to each other.
In order to switch targets, change the direction the Melting Point faces (as explained above) to the Level 2 Fortress.
Now the Melting Point will attack the Level 2 Fortress first, even though it’s farther away, because attacking the Level 1 Fortress would take more time due to the Melting Point’s slow turn rate.
In 2V2 matches, this trick can be used to attack the opponent on your teammate’s side.
