XCOM E3 demo video: 20 minutes of gameplay

2K Marin's 20-minute presentation of XCOM shown at E3 in June is now available in handy video format, so we can all enjoy a good look at its reboot of the much-loved X-COM series, and pretend that we're video games press about to write previews.

The demo is commentated by XCOM narrative director Jordan Thomas, who explains in a written introduction that it reflects "some pretty aggressive design changes" 2K Marin has made since unveiling the game in 2010.

"Our first crack at adapting XCOM to a more personal, real-time experience was way too much within our creative 'comfort zone,'" Thomas writes. "It was kind of a run-and-gun affair, without a lot of focus on the command of your squad, or indeed on tactical play itself."

Our Garnett Lee noted, when he saw this demo build at E3, "It's not the turn-based tactical combat game of the old games, but what I saw came a lot closer to getting the XCOM 'vibe.'" Now you can watch for yourself and make up your own mind.

XCOM is slated to launch for PC, Xbox 360 and PlayStation 3 on March 6, 2012.
