By the look of this game it appears that it's name was changed from XCOM to The Bureau: XCOM Declassified and was changed from an FPS to TPS (Third Person Shooter). However many gameplay elements from the original Title remained unchanged as well as it's RPG like squad system. It said that it will introduce players on how XCOM was started and eventually become organized from a group of FBI officials to a military organization and it will also introduce other events such as exploring the struggles of a scientist and cultural events tensions of the 1960's.
It's a real shame this game gets the rap it does. I'll admit, I was one who repeatedly panned the original reveal for looking like an attempt to cash-in on the X-COM name by tacking it onto an FPS. But even back then it was far from your run of the mill linear FPS romp and I wish I had realized that sooner. It probably would've helped if we knew about Enemy Unknown beforehand.
Anyway, the new info sounds really promising and it seems as if they've put the extra development time to good use. Hoping to see some gameplay soon.
