The map is set up so that the Survivors spawn in and around the Garage while, zombies spawn on the cliffs above, The map is dark so I recommend survivors stay in the lighted Garage to stay alive, there is an adjacent gas station that is lit up, you can try to hold up there but it's not recommended, 2 buttons are on the map one temporarily turns off all lights within the garage for 10 second, this button is located behind the garage on the generator and can only be activated every 90 seconds, the other button opens up the garage doors which is bad for the survivors, once opened it cannot be closed back up, this button is located in the office on the computer screen, a sewer path in front of the garage leads into the garage itself, and a hole in the the top of the office part of the garage and an open window in the garage, allows for multiple pathways into the garage aside from the doors, a shotgun for extra ammo is located near the dumpster in the rear of the building, though it can be played normal infection, the nightmare gametype makes it so all players can't use the Rally Scouts hogs on the map, and zombies have advanced radar to help find hidden Survivors, also last 60 seconds of the rounds puts navpoints on all survivors that are remaining, but anyways please do enjoy nightmares
