So, I finished the game and have got the worst ending (shortened the gameplay by killing Granny Rags and not even meeting Slackjaw). Well, that’s just one big NOPE. I felt so bad killing everyone and seeing the consequences of what have I done in the ending :c And the worst thing (in my case Calista were there too).
Also, as I have been playing stealthy-shmealsy all the time before, it turned out that I suck at the infightng. And, I have to admit, killing your enemies from the rewired watchover is FUN :D
