In many ways, Quarantine is the most frustrating game in the series. For one thing, you'll once again be playing more or less the same highly repetitive game. This means, from a third-person perspective, you'll be controlling our hero Kite, who'll run around randomly generated fields and dungeons filled with monsters with up to two of his friends in tow. Only now, the monsters hit you harder and take more hits to kill, and the bland, repetitive dungeons are sometimes even longer. Furthermore, the story-specific areas you'll need to go to will often require a large number of "virus cores," which are basically the keys you get either from specific events, occasionally from dungeons, or mostly as a random bonus for using Kite's "data drain" move on a weakened foe.
