I like what I see too, although I doubt the actual game will deliver the same character experience seen in that video. I'm guessing the end result will resemble something like State of Decay, where different characters have different strengths and weaknesses, but dialogue is genericized and context-based.
And I wasn't thinking about it until someone pointed it out over in the RPS comment section, but the amount of gunplay is jarring considering the game's based in London, which is pretty much a gun-free society. Given the criticisms of the last game were focussed around the amount of gunplay in the game, I would have thought this would have been the ideal opportunity to make a game less focussed on guns.
