Hello!
I’m currently on the Apprenhension chapter of this great game however when I enter that room where the lights go out and you get “kidnapped”, nothing happens… I’ve killed every other mob in the area and i go in there and nothing happens… Is this a common bug? or have I missed something?
Thanks for help!
Are you sure you went into the correct room? There’s multiple rooms. The correct one is behind the doors you have to open with the switch.
I got it! I was finally kidnapped! I ran around here for nearly two hours before i got it! Thanks all!
