Detailed walkthrough for Part 37 of Portal: Revolution, covering "My Finest Moment," "Mission Impossible," and "Race Against Time" levels. Includes strategies for saving Lemmings and completing objectives within time limits.

Walkthrough
  1. 1
    Part 37 - Lemming running around by himself: Prevent a lone Lemming from activating a switch that fills a water tank. Have him bash through a staircase to create a path.
  2. 2
    Main group in water tank: Assign one Lemming as a climber and floater to go out each side.
  3. 3
    Right side climber/floater: Guide this Lemming through super-speed devices to a switch that closes the floor above. Have him build left towards a portal and then build to the wall upon exiting.
  4. 4
    Other climber/floater: As the first Lemming exits the portal, this Lemming will approach a switch that opens the door for the builder. Once the door is open, make this Lemming a blocker and detonate him to keep the door open.
  5. 5
    Main group release: Build the main group out of their habitat and set the release rate to 99.
  6. 6
    Builder near next portal: The builder will reach a switch that opens the floor for other Lemmings. Build over the small wall after the switch, then over the single steel block before the long steel segment leading to the balloon.
  7. 7
    Balloon arrival: Ensure the main group reaches the balloon as you finish the bridge.
  8. 8
    Lone Lemming rescue: Return to the single Lemming and make him a climber to get him out of his predicament. Have him build to hit his head near the portal to guide him to the exit.
  9. 9
    099. My finest moment (50 Lemmings, save 49, 3:00): This level requires the pause trick (press P).
  10. 10
    Pause Trick Explanation: While paused, you can rotate the level and assign tasks to Lemmings.
  11. 11
    Initial Lemmings: Let two Lemmings pass a counter (reading 10). Have the third dig down to a single steel block.
  12. 12
    Pause and Mine: As the third Lemming starts digging, press P and rotate to the first Lemming (who passed a thin floor strip). Click the miner button while paused to have him mine.
  13. 13
    Second Lemming mines: When the second Lemming turns, have him mine after passing the thin floor.
  14. 14
    First Lemming builds: While the second Lemming mines, return to the first miner and have him build when he reaches open air.
  15. 15
    Pause and Bash: As the first Lemming starts building, pause again. Go to the second miner. When he reaches the steel block, have him bash through to the tunnel with other Lemmings.
  16. 16
    Release Rate: While the second Lemming bashes, raise the release rate to 99.
  17. 17
    Building miner: Return to the building miner. Mine down through a small piece of wood below the ledge to save him from falling. Bash left through the wall and build over the pond.
  18. 18
    100. Mission Impossible (20 Lemmings, save 20, 2:00): This level requires precise room-by-room execution.
  19. 19
    Upper Left Exit: Have the first Lemming dig while facing left.
  20. 20
    Upper Right Corner: Have a Lemming build one bridge to the next ledge.
  21. 21
    Bottom Right Corner: Have a Lemming bash.
  22. 22
    Upper Left (again): Start the digger bashing left.
  23. 23
    Lower Left: Make a Lemming a climber as they head left. Have him climb the thin pole, then dig through it.
  24. 24
    Right Side: Build and bash in the appropriate quadrants.
  25. 25
    Lower Left (again): Repeat pole digging. Build up from 4-5 rivets to the right of the arrowed wall.
  26. 26
    Top Left Quadrant: Bash through the final wall and build. Aim to finish with about two seconds left.
  27. 27
    101. Race Against Time (45 Lemmings, save 45, 3:00):
  28. 28
    First Lemming: Make him a floater at the very bottom as he's about to splat, allowing a fast freefall. Build at the very edge.
  29. 29
    Hanging Staircase Lemmings: Make the first a climber and a floater. Have the second dig to the left of the steel block on the right.
  30. 30
    Builder's Action: As the second Lemming digs, your builder will walk off. Build 3-4 steps up the huge wall to the right to turn around, then build at the bottom of that staircase.
  31. 31
    Connecting Bridges: Ensure your two staircases connect.
Tips
  • The pause trick (pressing P) is essential for precise Lemming control in "My Finest Moment."
  • Careful timing and assignment of roles (climber, floater, blocker, miner, builder) are crucial for all levels in this part.
  • For "Mission Impossible," focus on executing actions in each quadrant as described to meet the tight time limit.
  • In "Race Against Time," utilize the floater ability for rapid descent and ensure bridges connect correctly.
  • Successfully completing Part 37 allows progression in Portal: Revolution.
  • Specific Lemming saves and time bonuses contribute to overall level scores.
