There are 2 denizens of interest that i know of. One at the entrance to the tunnel, the second at the cornfield entrance. Instead of latching your head first it's like they stab you in the back before latching and do quite a bit of extra damage to you, also shakes the controller.
Maybe focus on these 2.
I am not calling you a lier, but this seems doubtful to have two specific denizens... I guess I will look into that. I was hoping someone like Deathbringer or others who devoted so much time to TranZit would weigh in on this jetgun topic.
