This step needs four players. First, kill Shadow Men. Here’s my Link on how to do that if you still don’t know! After you kill Shadow Men, White Screen will appear and you have to find a mist. IF you didn’t get in, you’ll be down or if you are in beast mode. You will just going back to human.
Next, three players must be in beast mode and other one who is human has to call the train. To be in beast mode, Margwa will spawn and you have to kill just one (Note: not all curse fountain are active, so keep looking around). Then, Those three players (beast Mode) has to go on each train stations (Canal, Footlight and Waterfront). Each of those stations has a Electric box that can be zap. Once the other player call the train (Human), quickly zap the box and someone has to run (Again) quickly to junction to zap those Gatekeepers. This Step needs good communication. Tip: Better if all can players will run quickly and zap those gatekeepers to finish it.
