DOOM 3 Hints
How can I get to the airlock that leads to Recycling Sector 2?
1 of 3: After you exit to the Martian surface and blast the first revenant, move along until you find a wrecky building with another revenant in it.
2 of 3: In the building, find the "stairstep rubble" and jump up it as high as you can go.
3 of 3: This will get you to where you can hop up onto a high-up walkway that will lead you straight to the airlock you seek. (Watch out for cacodemons!)
