Defiance is an MMO shooter game released by Trion Worlds. The gameworld is set in a future dystopia on Earth, where alien settlers wage bitter war with humans. Travel to the San Francisco Bay area as an â€œArk Hunterâ€? to search for alien technology, take part in missions and compete with other hunters. The first MMOG released in tandem with a TV show, the world in Defiance is constantly shared with other players, and yet events that transpire in the show also affect the online world. A continuously shifting wasteland thatâ€™s packed with bandits and intense gun battles, this game is also layered with character and RPG elements that bring colour and intrigue.
