Defiance when it was on sale for $13.59 on Steam earlier this month? Your hesitation has paid off, my friend, as Trion Worlds is now offering the game for even cheaper. The studio has the standard digital PC edition of Defiance on sale for $9.99 through its website.
The deluxe digital PC edition is also marked down from $44.99 to $24.99. Both editions come with several in-game goodies, although the deluxe edition has more.
