Doom 3 Walkthrough - Recycling Sector 1 (Monorail Skybridge)

Doom 3 Walkthrough Screenshot 1. The autosave calls this level "Recycling Sector 1" but the loading screen identifies it as "Monorail Skybridge." Go figure.

Doom 3 Walkthrough Screenshot 2. The walkway collapses and you find yourself suddenly outdoors without air. Carefully drop to the ground below. Keep right.

Doom 3 Walkthrough Screenshot 3. Two Cacodemons patrol the area. Ignore them and rush around these rocks to the right.

Doom 3 Walkthrough Screenshot 4. Grab the air canister seen here on the right and recycle the airlock on the left.

Doom 3 Walkthrough Screenshot 5. Fend off the Cacodemons while you wait for the airlock.

Doom 3 Walkthrough Screenshot 6. Proceed down the corridor to trigger this Pinky, then backtrack and toss two grenades to send him flying.

Doom 3 Walkthrough Screenshot 7. This zombie attacks from the right. Defeat him then grab the shells and armor.

Doom 3 Walkthrough Screenshot 8. As you approach the health terminal, this fat zombie attacks from the left, followed by a maggot behind you. Two clips are in the near-left corner. Proceed through the door ahead.

Doom 3 Walkthrough Screenshot 9. A brief cutscene introduces this missile-launching enemy, the Revenant.

Doom 3 Walkthrough Screenshot 10. Do your best to dodge his guided missiles and fire away.

Doom 3 Walkthrough Screenshot 11. This medkit is around the left corner.

Doom 3 Walkthrough Screenshot 12. Ignore the stairs for the moment. Instead, ramp up the fallen catwalk on the right.

Doom 3 Walkthrough Screenshot 13. Toss a grenade into this room to clear out an Imp. Inside you'll find an ammo belt, a medkit, cells and a clip.

Doom 3 Walkthrough Screenshot 14. Return to the stairs you passed a moment ago and battle another Revenant.

Doom 3 Walkthrough Screenshot 15. Follow the stairs to this door ahead.

Doom 3 Walkthrough Screenshot 16. Grab the adrenaline hypo on the left then pump two shotgun blasts into the Pinky. A fat zombie attacks from the right. Far-right is an Imp guarding cells and clips. Continue through the door on the right.

Doom 3 Walkthrough Screenshot 17. A micro-mini cutscene plays before this Imp spawns, followed by a maggot plus two more Imps. Grab some clips from shelves on the left before calling the lift ahead.

Doom 3 Walkthrough Screenshot 18. Ride the lift down and defeat three maggots. Grab the cells on the left and the medkit/grenades on the shelves ahead.

Doom 3 Walkthrough Screenshot 19. Uh oh. Revenants are waiting in each of these corridors. Toss grenades their way then grab the cells from the left corridor.

Doom 3 Walkthrough Screenshot 20. Continue down the corridor on the left to find armor, a medkit, shells and a clip, spawning a total of four Imps. Ready your shotgun before opening the door seen here on the left.

Doom 3 Walkthrough Screenshot 21. Pop that Imp but good!

Doom 3 Walkthrough Screenshot 22. Next up are a pair of Pinky Demons. Toss grenades their way and introduce them to the ceiling.

Doom 3 Walkthrough Screenshot 23. A third Pinky spawns by the door. If you're this close, switch to the shotgun.

Doom 3 Walkthrough Screenshot 24. Continue to this fat zombie and maggot. Another fat zombie attacks from behind. Note the armor on the right.

Doom 3 Walkthrough Screenshot 25. This Imp is guarding shells, cells, an ammo belt and clips on these shelves.

Doom 3 Walkthrough Screenshot 26. This is a busy room. Three more zombies are hiding back here.

Doom 3 Walkthrough Screenshot 27. Before climbing these stairs, snatch the shells underneath. You'll battle an Imp at the top.

Doom 3 Walkthrough Screenshot 28. Follow the catwalk to trigger this maggot. Note the medkit on the right.

Doom 3 Walkthrough Screenshot 29. Before taking the medkit, toss a couple grenades into this corner alcove to destroy a lurking Revenant.

Doom 3 Walkthrough Screenshot 30. Follow the walkway to find some cells in a corner to your right, then this armor vest and clips are perched on a pipe to your left. Proceed cautiously as two Imps spawn if you take them.

Doom 3 Walkthrough Screenshot 31. Approach this door -- don't go through it immediately. Instead, hold back and pummel the Revenant waiting beyond, using the doorway as a choke point for his missiles. Once you enter the doorway, an Imp pounces from the left.

Doom 3 Walkthrough Screenshot 32. This maggot is waiting on the other side of the next door.

Doom 3 Walkthrough Screenshot 33. Your objectives are updated. Hop across the broken catwalk through the doorway on the right.

Doom 3 Walkthrough Screenshot 34. Ready your shotgun for this leaping Imp, plus another to his left.

Doom 3 Walkthrough Screenshot 35. Toss a grenade to those explosive barrels before this Imp comes around the shelves. A maggot attack follows. On the shelves are a medkit, shells and grenades. An armor vest is in the far corner.

Doom 3 Walkthrough Screenshot 36. Up the stairs, this Imp pops out from behind the crate. A medkit is in the corner behind you. Continue through the door on the left to yet another Imp.

Doom 3 Walkthrough Screenshot 37. The maintenance safety video on the left is a must-see. Read Nick Sadowayj's PDA to learn the code 483 for a storage cabinet by the monorail airlock. Use the terminal to extend the service ladder on the right. Heal at the medical station further right before ascending the service ladder to a pair of awaiting Imps.

Doom 3 Walkthrough Screenshot 38. Ready your chaingun at this juncture to battle a Cacodemon as you follow the pipe to the opposite walkway far-right. Note the shelves far-left, where you'll find clips, shells, cells and a medkit.

Doom 3 Walkthrough Screenshot 39. Use this terminal to shutdown the broken pump and complete the objective. Ascend the ladder to the left.

Doom 3 Walkthrough Screenshot 40. Backtrack to this position. The door on the left returns you to this room and should only get you some armor and clips you may have left behind. Plus, you'll have to fight three Imps and a maggot. I recommend you proceed directly through the door on the right -- be ready for an Imp on the other side.

Doom 3 Walkthrough Screenshot 41. Battle another Imp in this previously-flooded room.

Doom 3 Walkthrough Screenshot 42. Note the armor vest in the alcove on the left. Ramp up to stairs and a doorway ahead.

Doom 3 Walkthrough Screenshot 43. An Imp spawns. Unfortunately for him right next to some explosive barrels. Climb the ladder far-left.

Doom 3 Walkthrough Screenshot 44. Grab this medkit from the crate -- you'll be back in a moment.

Doom 3 Walkthrough Screenshot 45. Continue down the hallway to trigger two Pinky Demons. Rush back to the crate and jump on top. From this position of relative safety you can pummel the Pinkies.

Doom 3 Walkthrough Screenshot 46. Armor, cells, clips and shells are on the left. More armor is by the health station on the right. Continue through the door straight ahead.

Doom 3 Walkthrough Screenshot 47. Trites attack, front and rear. Plus an Imp spawns as you reach this position.

Doom 3 Walkthrough Screenshot 48. Reach this medkit and cells on the left and a Maggot attacks from the front while a Trite sneaks up behind you.

Doom 3 Walkthrough Screenshot 49. This Revenant is waiting up ahead. Follow the stepping stones to reach the doorway on the right.

Doom 3 Walkthrough Screenshot 50. After your first steps an Imp attacks from this area on the left. Toss a grenade his way.

Doom 3 Walkthrough Screenshot 51. Another Revenant attacks before you reach the doorway -- the Chaingun works well against him.

Doom 3 Walkthrough Screenshot 52. Defeat a Maggot and grab the medkit on the right. Anthony Garza's PDA on the counter ahead hints that a rocket launcher is to be found.

Doom 3 Walkthrough Screenshot 53. Another Maggot and this Imp are ahead -- but the important thing to note is on the shelf below - the rocket launcher! Two medkits are beneath, and more rockets are in an alcove to the right. Continue through a door on the left.

Doom 3 Walkthrough Screenshot 54. Cycle this airlock to return to the Martian surface once again.

Doom 3 Walkthrough Screenshot 55. A Revenant is firing at you from above - a great time to try out your shiny new rocket launcher! Note the two oxygen tanks visible here. The door far-left is non-functional. Instead, approach that bunker straight ahead.

Doom 3 Walkthrough Screenshot 56. Another Revenant is firing at you from inside. Note a third oxygen canister here. Defeat the Revenant then head inside to find a medkit and more air.

Doom 3 Walkthrough Screenshot 57. Hop up to the walkway above.

Doom 3 Walkthrough Screenshot 58. Cacodemons spawn. Ignore them for now. Run straight between those pipes and fall to the doorway ahead.

Doom 3 Walkthrough Screenshot 59. Grab the oxygen canister on the left and open the door with the panel on the right.

Doom 3 Walkthrough Screenshot 60. Fend off the Cacodemons as you rush inside and activate this panel to load the next level.
