Level 11: The ascending pillar scenario
- 4 minutes, 100% of 50 lemmings, release rate 20
Turn the first lemming into a digger the moment he lands. Turn the second lemming into a digger as soon as he is slightly past the pit dug by the first one. Turn each of them into builders as soon as their pits are deep enough, then turn the one in the right pit into a basher when he is heading to the left; then turn a lemming going left into a climber (if you're quick, perhaps with judicious use of the pause hot-key, you can give this skill to the basher). Build up to each pillar in turn, being careful to time your bridges so that they neither fall short of the pillar nor touch it and thereby turn the scout back to the right. At the last pillar, dig, mine left, dig, turn (using a builder), mine right, dig, turn, and mine left, breaking out of the pillar fairly low down. Build across the gap, and just before this is complete, have one of the trapped lemmings build left out of the pit.
Level 12: Livin' On The Edge
- 5 minutes, 80% of 10 lemmings, release rate 1
This level is so-called because it's best tackled by building from as close to the edges of platforms as possible; it's frustrating because, even with the above tactic, there appear to be two builders too few. However, analysis of the layout using a bitmap editor shows that each platform (including the one made by bashing through the wall) is two pixels closer to the previous one than that one was to its predecessor. This is the secret of beating this level.
Build up to the wall (you will need two builders) and block both ends of the entrance platform. Bash through the wall, and immediately after breaking through, build to the next platform (you will need two builders again, and will probably also need to dig before your bridge overshoots the end of the platform). Build to the next (two builders and a digger again); the remaining ramps will only need one builder each. Release the blocker.
