Previously on X-COM...
Hello, commander. In response to the alien threat, this council of nations has chosen to activate the XCOM project. You have complete command of XCOM headquarters. You must learn more about the enemy to expand our capabilities, and the abilities of our operatives.
Good luck, commander.
Now the conclusion.
Dear Unknown Alien,
As the commander of an unknown, secret government agency that reports directly to a mysterious council consisting of a bunch of wankers that are harboring exalt operatives and a bald headed dude, it is my privileged and honor to invite you into our secret facility.
During your stay you will be subjected to a luxurious amount of time in a specially built alien containment facility. As your host, I can guarantee that you'll be subjected to all forms of torture and interrogation by our very own world, renown Dr. Valen. You'll witness our most secretive, controversial and cutting edge techniques firsthand! Once you've unfortunately expired after spilling your guts - hehe - you'll be treated with upmost respect as we disect your body for further examination.
Book your reservation today! This is limited opportunity - you never know when the silly council will disavow us for political reasons. First come, first serve!
Sincerely,
Commander, X-COM HQ.
Vigilo Confido
