Battles in Shin Megami Tensei: Devil Survivor Overclocked are scored and after you beat the game those points can be used to unlock survivor awards. These aren’t trophies, survivor awards effect the game in various ways.
You can restart the game with the macca (money) you earned or change which demons show up. So, if you’re planning to see all of the endings you can change the rules of Devil Survivor Overclocked for each run.
Shin Megami Tensei: Devil Survivor Overclocked comes out on August 23 in North America.
