Detailed walkthrough for Part 22 of Portal: Revolution, covering strategies for Lemming levels, including 'The High Dive' and 'Battle o' Lemmuckburn', and how to overcome level-specific challenges.

Walkthrough
  1. 1
    Part 22: The High Dive
    • This level is unplayable due to a game glitch that causes the program to shut down upon loading.
  2. 2
    A patch is available online but does not fix the error.
  3. 3
    Progress can continue by beating the levels before and after it, thanks to the game's branching system.
  4. 4
    If a fix is found, players are encouraged to share it.
  5. 5
    Part 22: Battle o' Lemmuckburn
    • Set the release rate to 1 and let two Lemmings go ahead.
  6. 6
    Set up a blocker for the rest.
  7. 7
    Let the first two fall to the ledge below.
  8. 8
    Have the first Lemming dig near the steel, close to the edge.
  9. 9
    The second Lemming will fall into the hole as the first digs.
  10. 10
    Once the digger is below the steel, have him bash right.
  11. 11
    Have the walker bash left for about three seconds.
  12. 12
    Make the walker dig down to the weasel controlling the switch.
  13. 13
    The switch drains the pool to the right and refills it to the left. Prevent the weasel from turning it left by bumping it off.
  14. 14
    When the digger reaches the bridge, have him dig through it on the right side of the lever. He will die, but the weasel will also die.
  15. 15
    The pool should remain drained. Make the Lemming who was bashing a floater to prevent splatting in the pool.
  16. 16
    Once in the pool, make the floater a climber. He will exit on the right.
  17. 17
    Dig a deep hole (not all the way through) between the pool edge and the wall. Use a builder to cut it off when deep enough.
  18. 18
    The climber/digger/floater will build one step, hit the wall, and climb out to the left.
  19. 19
    Build a bridge to the left while in the pool, tall enough for other Lemmings.
  20. 20
    Let him climb over the right edge of the pool again. Build one bridge over the hole you dug.
  21. 21
    After building, bash through the wall. The weasel will attack your Lemming, but it will fall into the deep hole and be trapped.
  22. 22
    Bomb the blocker and send the other Lemmings.
  23. 23
    Make one Lemming a climber.
  24. 24
    When others are in the drained pool, have the climber bash through the next thin wall. The switch on the other side is less critical now.
  25. 25
    Have bombers ready.
  26. 26
    When the climber is halfway up the giant plateau, set off the bomber. This should blow a hole in the thin wall.
  27. 27
    Send another climber through the hole towards the balloon.
  28. 28
    Have this climber build so his head hits the large square of land jutting from the steel ceiling, causing him to turn around.
