XCOM: Enemy Within review [Lazygamer]

Matt Buckley: "Firaxis could easily have made us wait for a full-fledged sequel to XCOM: Enemy Unknown. But with Enemy Within, we’re introduced to a vast array of features that legitimately change the way the game is played — at half the cost of a fully priced title. It truly earns the moniker of “expansion,” and fans of the core game would be remiss to pass on it. For the rest of you who haven’t yet experienced the punishing yet rewarding gameplay of XCOM, there has never been a better time to jump in."
