From the campaign:
RESISTOR_ is a fast and intense two-player competitive card game that relies on hidden information and tactical decision-making. Through the manipulation of double-sided cards on the table and in your hand, you create a connected line of your color that goes across the board into your enemy's base to score a point, increasing their DEFCON level. Score four times to push the enemy past DEFCON 4 to successfully launch your nukes without a counterstrike.
Each turn, you have three different actions to change the state of the board. You must take all three before you can score a point. This means even if you have a connected line at the beginning of your turn, you must figure out how to keep it while still performing the actions.
But even when it's not your turn, you must pay attention. When your opponent performs their actions, you will learn more about the cards in play, which is information that can be used when your turn comes around again.
On top of that, there is the Resistor card, which can be used to chaotically change the entire face of the board, or to strategically heal yourself while undermining your opponent's plans. Beware, though, because whenever Resistors come into play, the board is going to shrink, speeding up the scoring and intensifying the gameplay.
