Essentials[edit]

(The following walkthrough was played on Ultra-Violence difficulty and for 100% in all three categories as noted.)

You will begin with a shotgunner and zombieman directly in front of you. Kill them both, but beware of the two arachnotrons on a raised platform to your left around the corner. Quickly go left and hug the side of the platform to prevent them from attacking you. Grab the box of shotgun shells and four shotgun shells, then—still hugging the platform—go around and pick up the dead shotgunner's shotgun. You can now use whatever cover or method that you wish to take out the arachnotrons. If you go straight past the platform, there will be a shotgunner on your right around the corner, as well as some armor. You will also see a planter containing a chainsaw and additional armor for later if you need it.

Go east past a building with some columns to your right, but beware the four demons hiding among them. The area they are in also contains a medikit and another box of shells. A different building with the blue door will be on your left which has open windows allowing the shotgunners and zombiemen within to attack you. Once you pass the buildings, there will be many shotgunners and zombiemen to the south, as well as many much further north. If you continue east you will also see a nukage pit with arachnotrons and barrels in it. Ignore them for right now, and take out the rest of these enemies as you see fit. Monster infighting can be utilized well in this map to conserve ammo.

At any point where you think you may need it, a partial invisibility may be obtained from atop a crate to the east. To get it, you must cross the damaged part of the street in front of the yellow key building (see below) to lower this crate. You must then quickly strafe jump across the nukage and grab it before the crate rises again (secret 2). Be careful, as it is a very tricky jump.

Continue north. To your east is building with shotgunners and zombiemen, to your west is the building with the blue door and a chaingunner on top, to your northwest is a different building with chaingunners on top, and to your northeast is a building with locked doors. Around the corner of the blue key building will be a mancubus and barrels. And importantly, in the road to the north a super shotgun awaits. Deal with the enemies you wish to, but head into the east building when you can. Take out the enemies and pickup the chaingun in here, as well as a box of bullets around the corner from some monitors guarded by a demon. Open windows to the east give you a view of chaingunners and revenant that you may take out from here. (Depending on how and when you decide to kill the map's enemies, additional enemies can attack you or be attacked by you through the various windows.) Grab the yellow key around the corner, then go back and press the northern wall in this same building to get the BFG9000 (secret 1). Grab any medikits in this building you may need.

Exit the building and continue down the road toward the wall. A chaingunner will be hiding around a corner to the west, and several enemies on or surrounding a truck with barrels, a box of rockets, and stimpack. Once they are dead, you can run off the north edge of the truck bed to collect an energy cell on top of a nearby crate.

Rounding the next corner, an arachnotron will be perched atop some crates. Kill it while also be wary of any stray chaingunners wandering around. Now return to the truck you past a few moments ago. Stepping onto the truck bed will lower a platform allowing you to reach the crates the arachnotron was on. Quickly run to it before it raises again to claim a box of rockets (secret 4). The yellow key room filled with demons will be to your west. You can kill them through the window now if you wish to avoid dealing with them later. If you are patient, you can kill them through the window with the chainsaw to conserve ammo.

Go south to the next building. There may or may not still be chaingunners in here, depending on whether they all walked out or not. Enter this building and you will see a platform above some nukage at the south end. Step on this platform, being careful not to fall in, then quickly run outside to grab a plasma gun that was previously concealed by a crate which has temporarily lowered (secret 3). Continue south to the end and deal with the arachnotrons in the nukage to the west (there will also be a spectre wandering somewhere in the nukage pits if you have not killed it already). The exploding barrels may help you here. You may claim the soul sphere in the nukage now by running into the nukage, take the small opening to the north, then immediately turn right and run for the platform that will automatically lower for you to get back out.

Exit this building again and head north then west past the truck from earlier. Now go south and west to the nukage river where the mancubus was earlier. You will need to jump in and go under the building, but you can run along the edge next to the nukage to minimize the amount of time you spend in it. Run in, turn left at the fork, then left again to some stairs on the left and out of the nukage (another spectre may be here unless it was activated earlier and moved). At the top of the stairs will be a Hell knight to the right blocked by two vertical beams, and multiple shotgunners and chaingunners (as well as a berserk pack) to the left. Take out the enemies to the left to obtain the blue key. You can also kill the Hell knight through the beams now to make it easier for later.

Unfortunately, you will have to reenter the nukage to get out of here, so move quickly. Go down the stairs, turn right, turn right again and go to the very end, turn right again and kill the unfortunately placed arachnotron down here. Take the lift that has automatically lowered out of the nukage. This will cause a door from the building to the east to open, releasing a few shotgunners and a zombieman. Take them out and jump off this building.

Now with the blue key in hand, head back to the building with the blue door from near the very start. Open the blue door, and kill the Hell knight up the stairs if you did not already kill him through the beams earlier. Make sure to grab the rocket launcher and the health bonuses surrounding it. Go up the stairs and to the right to collect the backpack on the small balcony. This will also cause a door to the building northeast of here to open. Kill the zombieman and shotgunners that emerge, then head back in the building and to the western opening. You are now on the other side of the two beams you encountered earlier while getting the blue key. The beams will automatically lower when you get close, but do not pass them yet. Instead, just get close to them, and this will open a small door to the east. Now that you see what you must do, go back and get ready to run past the beams and into this small chamber to grab a megaarmor and health bonuses (secret 5). Quickly run back out and past the beams going south. If you do not run past the beams before they rise again you will have to go back through the nukage to get out. You should now have 100% for both items and secrets.

Go south and out the door to the right to the platform the first arachnotrons you encountered were on. You will see the red key. Stepping onto this platform will lower a wall behind it, releasing two cacodemons. After killing them, head to the red door, which is at the north of the map right next to the truck from earlier. Open the door, kill the chaingunner to your right and the two cacodemons to your left. You can press a button here to lower a wall and grab a (probably deceased) chaingunner's chaingun. Go east down this hall toward the nukage, killing the demon hiding to the right, and through the yellow door. Pressing the exit button in this room will not exit the map, but instead lower a wall and platform in front of you with a mancubus. After killing him, press the newly available button behind him to exit the map.

Other points of interest[edit]

If you need armor by the end of the map, do not forget about the extra armor in the planter with the chainsaw that you passed near the beginning. Get this before exiting the map.

Secrets[edit]

  1. At the opposite end of the hallway that leads to the yellow key, you can open a northern wall to get a BFG9000. (sector 4)
  2. A lone crate in the southeast part of the map has a partial invisibility. To get it, you need to go across the damaged portion of the road in the center of the map, slightly west of the building with the yellow key and Secret #1 in it. After going across the damaged road, make a running jump to the north across the nukage all the way to the lowered crate. (sector 0)
  3. West from Secret #2, there is a passage filled with nukage. At the end of the toxic passage, there is a lift. Step on it (the lift will automatically lower down when you get closer from its western side) and ride up to get out of the nukage. Then, from this lift, quickly run out of the building using the exit on the east and run south to grab the plasma gun. (sector 105)
  4. From Secret #3, go north until you notice a truck on the west. Get on it and you will hear a lift being lowered. Get off the truck and run back where Secret #3 was until you reach the lowered crate (the most northern one from the stack). Ride it up and you will reach a box of rockets on this stack of crates' southern part. (sector 108)
  5. Open the blue door and climb the steps, then go to the next hallway. Go north towards the bars and they will lower. Along with the bars, an alcove opens up with health bonuses, a megaarmor, and a switch which lowers the bars should they rise again. (sector 81)
