Navigate the tricky final stages of Portal: Revolution with our detailed Part 39 walkthrough. Learn how to manage your Lemmings and overcome the last obstacles.

Alright, we're on the home stretch with Part 39! This one's a bit of a head-scratcher, but we'll get through it together. The goal here is to get your Lemmings across a series of tricky gaps and hazards. Pay close attention to the order of operations, and don't be afraid to pause and re-evaluate.

Walkthrough
  1. 1
    You'll start with your first Lemming needing to build a bridge about 4.5 rivets away from the wall. The Lemming will inexplicably turn around when it hits the ground, so don't worry about that.
  2. 2
    Now, switch to the Lemming that bashed through the right wall earlier. This time, bash through the left wall. Pause the game and return your attention to 'Second', who should be near the hole they made in the stairs.
  3. 3
    Have 'Second' build a bridge at the same spot where the original climber/floater built theirs. This will essentially repair the bridge. As soon as 'Second' starts building, pause again and switch back to 'First'.
  4. 4
    'First' should be near the right wall of the first water tank. Make 'First' turn around. You should have one builder Lemming left at this point.
  5. 5
    Return to the main group and have one Lemming bash through the arrowed wall to the right.
  6. 6
    Now, 'First' is in the lead, 'Second' is behind them, and the rest are trailing. 'First' will walk up the bridge towards the metal door (which should be open). To the right of the door is a small patch of diggable ground. Build a bridge from the right edge of this diggable ground to connect with the next ledge.
  7. 7
    Once 'First' finishes the bridge, have them turn the lever to the right. This will move the rolling spiked log out of the way, safely to the end of the level.
  8. 8
    After the log is clear, have your digger Lemming dig at the diggable ground. 'Second' should be coming around soon and will climb out of their hole.
  9. 9
    When 'Second' climbs out, have them mine to the left. This should create a pit deep enough to contain them and prevent them from wandering off.
  10. 10
    Around this time, the digger should be near the bottom of their pit, and the rest of the Lemmings will start flocking in. Have a Lemming bash to the right to effectively end the level.
  11. 11
    Since you likely used all your assigned Lemmings and have no bombers, you'll need to click the nuke button to get rid of the single blocker Lemming remaining.
Tips
  • Don't panic if a Lemming turns around unexpectedly; it's part of the puzzle in this level.
  • The key is managing your builders and diggers efficiently. Pause frequently to assess the situation and plan your next move.
  • Make sure to clear the spiked log early; it's a hazard that can easily wipe out your Lemmings if you're not careful.
  • The nuke is your last resort for any remaining blockers, especially since you're likely to have used up all your other abilities.

You've completed Part 39! While there isn't a visible ending in-game, the ending sequences are accessible by playing the game's CD in a media player. Congratulations on beating Lemmings Revolution!
