MAP01: Back to Saturn X Radio Report is the first level of the first episode of Back to Saturn X. It was designed by Sarah Mancuso (esselfortium) and Richard Frei (Tarnsman), the former of whom composed the level's music track, "Entering". The par time is 1:15. In the official add-on version, this level's name is BTSX Contractual Obligation.

Beginning outside, the player enters a quite expansive station with a nukage river flowing through it, and finds the blue keycard which allows them to access the tram station and exit.

Go through the doorway on your left, then head towards the water-filled tunnel on your right (collecting a shotgun on the way) and follow it until you get outside again. Head north up some steps to an empty floor (there is an armor at the far end on Hurt Me Plenty skill level or lower), then go through the doorway in the north-west corner to kill a waiting imp and zombiemen. Go through another doorway in the south-west corner to reach a nukage pool with more zombies and a spectre, then follow the walkway south to another room and climb the steps on the south side to get on top of a bridge leading over the nukage. Cross the bridge to enter a curved hallway with a chaingun protected by one or more cacodemons, then head east into a large room with another nukage pool.

Follow the path east past the nukage to reach a hallway with some armor bonuses, then head straight forward through an open door and turn left to climb some steps. Follow the next hallway down to an outdoor area with some chaingunners, head south through a blue-floored room to find some steps that lead up to a ledge with an arachnotron, then open the door here to find the blue keycard above the second outdoor area you visited. Drop down and open the locked door on the west side, then flip the switch straight ahead to go down to another hallway. Follow this hallway to another lift and flip the switch on your right, which will bring you to the tram station (you will revisit it several times over the course of this WAD); from here you can board the tram at gate B (in the north-west corner) and press the exit screen inside it to finish the level.

Other points of interest[edit]

On reaching the hallway with armor bonuses, climb the south staircase to get a berserk pack.


  1. Upon first sight of the bridge (see screenshots below), turn right into the nukage to find an alcove containing a radiation shielding suit. Use the back wall, and it will lower to reveal an armor. (sector 139)
  2. After crossing the bridge, go in to the short tunnel at the end of the hallway, containing a medikit. Go outside into the nukage, and follow it round to a teleporter. You will be taken to an area containing a supercharge. (sector 161)
  3. From the north nukage pool, activate the lift on the east side to get to steps that lead up to a hexagonal balcony. If you stand on this balcony and look south-west through the low windows you will see a panel with red cables that you can shoot. Having done so, head west until you drop down a hole then follow the corridor to a blue teleporter behind some barrels. The teleporter leads to the river north of the building where you can find a super shotgun; after taking it, you will have to deal with a large number of monsters (including revenants and a pain elemental on Ultra-Violence and Nightmare) that teleport into the map. (sector 465)
