The folks over at Twitch have been streaming live gameplay demos from E3 all week. I know this, becuase every now and then over the course of the past few days I'd completely cut-off contact with my coworkers to enjoy a particularly compelling segment, like this one for The Bureau: XCOM Declassified.
I've been intrigued ever since Evan spent 30 minutes with the game a while back. I love the original XCOM, but I am no tactical commander -- I'm want to be in the line of fire. I also want to be in the 1960s. This is perfect.
Hit up Twitch for lots more live gameplay demos direct from E3 2013.
