Behold the trailer for XCOM: Enemy Unknown's expansion, XCOM: Enemy Within, and its interactive Extraction trailer. Because who doesn't love seeing a trailer for another trailer?

Once you actually jump into the experience, you'll be faced with an interactive trailer that tasks you with making decisions on the fly. As the Commander, you're in charge of deciding which tactics would be best to use in any given situation.

The Extraction experience puts you in charge of a team with one objective: hack the EXALT comm relays to get sweet, sweet intel. To do this, you'll need to keep your operative alive. Unfortunately, one wrong strategic decision can mean the destruction of your team. You'll have to choose whether or not to go loud with your weapons or sneak quietly, using your skills to blend into the environment.

Watch the trailer above to get yourself psyched up and then experience the Extractive interactive trailer here. XCOM: Enemy Within will be released on Nov. 12 for PC, PlayStation 3 and Xbox 360.
