I watched a friend stream through Gunslinger recently and got the urge to play through it myself one more time. As I say in the video I really dig this game, it is the kind of thing I would like to see more studios doing. A small targeted experience, it has satisfying gunplay, entertaining story and doesn't outstay its welcome.
It seems like they settled on a fairly interesting narrative approach fairly early on in the development process and they really got to play around with it. I have not seen any other game use an unreliable narrator framing device quite the way this does.
There should be a total of nine episodes in this season, one per chapter of the game. I hope you enjoy the ride as much as I do.
