XCOM - "What Is XCOM?" Developer Diary

Featuring a bold new origin story told from a first-person perspective, XCOM pits Special Agent William Carter and his team against the threat of human extinction from an insidious otherworldly force. But every enemy is an opportunity – players will strike surgically against the alien menace, capture their technology, and by the science of desperation – turn the invaders' weapons against them.
During the first XCOM Dev Diary, leads from 2K Marin dive into the background of the game's original story, the creation of XCOM as an organization and give gamers a tour of the base.
