To help get you acquainted with the class trial in Danganronpa 2: Goodbye Despair, NIS America released the 2nd official trailer for the game, which you can watch above (go to :30 to skip the intro and 1:00 to start learning about the class trial).
Here’s the description for Danganronpa 2:
Jabberwock Island – once a popular tourist destination, this now uninhabited island remains oddly pristine. You and your classmates at the elite Hope’s Peak Academy have been brought to this island by your super-cute teacher for a “lovey-dovey, heart-throbbing school trip.” Everyone seems to be having fun in the sun… until Monokuma returns to restart his murderous game! Trapped on this island of mutual killing, your only hope of escape rests in solving the island’s mysteries. But be warned – sometimes the truth can be its own despair…
Danganronpa 2: Goodbye Despair releases on September 2 in North America and September 5 in Europe for the PlayStation Vita.
