XCOM: Enemy Unknown-1R
In the beginning of the 21st century, the number of UFOs sightings and reports grew through the world until their unknown origin and hostile behavior started to alarm Earth's political and military leaders. Deciding to pool their resources together, a council of the world's wealthiest nations activated the 'XCOM Project'. A covert international organization named XCOM - the eXtraterrestrial COMbat agency - was established and staffed with Earth's top soldiers, scientists and engineers, while operating out of a hidden subterranean headquarters equipped with the best weapons and equipment available. Tasked with the role of investigating and stopping the growing alien threat, XCOM started its operations on March 15th, 2015, under the motto "Vigilo Confido" - I am watchful. I am relied upon.
