Each round, the app tracks the time you have allotted to respond to each task, forcing you to think quickly, even as you must carefully measure the strategic implications of your decisions. However, the app does far more than track time. Its design is integrated deep into gameplay, and it permits both a mutable alien invasion plan and a dynamic turn structure. When you start a game of XCOM: The Board Game, the app randomly selects one of five different invasion plans. These plans represent the different, overarching strategies that the aliens might employ as they send forces against the earth’s different continents, create catastrophes, and target your base, pressing back against your resistance efforts. Destroy UFOs. Research alien technology. Defend your base. Uncover the alien invasion plan. Should you fail, humanity is doomed.
