Shin Megami Tensei: Devil Survivor is the latest in a string of off-shoots in the MegaTen series. The game marries the mechanics of a strategy RPG and the combat of the Dragon Quest series.
Devil Survivor's tale is one of isolation. Cut off from the rest of the world by a government lockdown in the middle of Tokyo, people try to cope with the stress and frustration of limited information and extraordinary circumstances. Taking your small band of teenagers through real-world sections of Tokyo, you attempt to understand the struggle between forces of good, evil and the nebulous in-betweens and their relationship to the emergence of demons around the city.
