Is Genocide your choice? Prepare to pay for your actions. The Bad Time has rung, and the executor is waiting for you patiently in the Hall of Judgment.
Repeat the legendary fight of Frisk and Sans, who have lost all hope in the protagonist. But in this game, you can choose the side to defend. That means you have a unique chance to play for the skeleton. As opposed to Frisk, he has more weapons to put in action, perplex, and clutch the enemy tightly. He avenges his homeworld this kid turned upside down.
The kid, instead, has only the infamous knife. But one hit of it can send the rival to his gone friends. So, both fighters must beware of attacks for their own reasons: one of vulnerability and the other of crazy magical damage of the undead.
