The Frontline is a major battlefield element in KARDS. The Frontline divides the two opposing players and lies between them on the battlefield.
How it works
The Frontline can be controlled only by one side at a time and can hold up to five units.
Units located in the Frontline are able to attack units in the enemy Support line, including the enemy Headquarters (HQ). Units in the Frontline are exposed to direct attack from units in the enemy Support line.
Moving to and from the Frontline
When your enemy doesn't control the Frontline and when it isn't already full with five units, you can move your own units into the Frontline. To do this, click on the unit in your Support line and drag it into the Frontline.
Units in the Frontline can generally not move back into the Support line. However, certain cards can Retreat units back into the Support line.
How to capture the Frontline
You take control of the Frontline by exclusively occupying the Frontline with at least one of your units. If enemy units are present in the Frontline, you first need to destroy those units before you can move your units to the Frontline.
