The last installment of Dying 2 Know, a 6 episode series of informational videos and behind the scenes looks at the upcoming Dying Light 2 Stay Human has been released, and this one is embedded with the launch trailer. I suspect the trailer will make a standalone appearance on the channel soon, but until that happens you can find it at the 14:26 mark in episode 6 below. The rest of the episode dive in to other various details like "Will there be co-op?" (yes, 4 person co-op even) as well as first impressions and an update on the contest announced in episode 1.
