XCOM: Enemy Within is an expansion pack for the turn-based tactical video game XCOM: Enemy Unknown. The gameplay and plot of XCOM: Enemy Within largely remains the same as XCOM: Enemy Unknown with some additional features. The player manages the XCOM headquarters in almost real time progress, but much of the gameplay consists of turn-based battles against the invading aliens and some with the rogue human faction EXALT across the globe. Similar to the numerous expansions of the Civilization series, the pack retains the core storyline but adds a broad variety of content.
