In Danganronpa: Trigger Happy Havoc‘s latest trailer, the nefarious Monokuma (the entity behind the forced imprisonment of a group of high school students) narrates as he explains how gameplay works.
The “Blackened” one is a student that murders another student. If the others can figure out the culprit, the Blackened will be killed. However, if the Blackened gets away with their crimes, all of the other students are put to death while (s)he escapes.
We also get a good luck at how the courtroom and investigation segments work, which functions as a rhythm game that uncovers the true culprit. The full trailer has been posted below, so check it out for yourself.
