When Command & Conquer 3: Kane's Wrath ships next year, it will add more than just new campaigns to the C&C3 experience. This expansion pack will also introduce two new subfactions for each of the three key factions in the game. Each of these subfactions will offer completely new ways of playing the game, with new tactics and methods to explore. GameSpot previously covered the Global Defense Initiative's new offerings, and in this preview they'll take a first look at the two new subfactions for the alien Scrin. Kane's Wrath will ship sometime in the spring.
