Part 12

Complete walkthrough for Part 12 of Portal: Revolution, covering levels 30-33: Lets play 'catch', 2 sides to every story, Wood you believe it?, and Wheelbarrows of Doom.

This section covers levels 30 through 33 of Portal: Revolution. These levels involve managing Lemming types, using terrain to your advantage, and precise timing.

Walkthrough:

1. 030. Lets play 'catch'
   Objective: Save 10 Lemmings in 5:00.
   Raise the release rate to ~40 and make all Lemmings climbers. Have climbers reach the top ledge. When they turn around, use a walking bomber about four logs from the lowest log on the bridge. Start the bomb timer on the second or third log from the right. For subsequent bombers, start the timer slightly further forward. This creates a mined tunnel to prevent Lemmings from falling and splatting.
2. 031. 2 sides to every story
   Objective: Save 50 Lemmings in 10:00.
   With blue Lemmings, place a blocker before the anti-gravity field. With white Lemmings, place a blocker under the entry hatch. Build bridges up to the wall with arrows pointing against you (right for blue, left for white). Behind each is the exit. When builders turn around, place a blocker near each wall and bomb it. This destroys part of the bridge. Build a little, then have a Lemming block near the wall and bomb him. This should take three bombers per side (eight Lemmings total killed).
3. 032. Wood you believe it?
   Objective: Save 50 Lemmings in 5:00.
   Have the first blue Lemming block to hold others back. Have the first Water Lemming block as well. When they turn left, have one build a bridge facing left from the steel edge of the pool. This provides a safe landing for normal Lemmings. To drain the pool, wait for a Lemming to touch the lever, then IMMEDIATELY block on top of it to keep it guarded. With the pool drained, build a bridge from the metal grate inside the pool facing right. Bomb the Water Lemming blocker, then the top blocker. If Lemmings get past the top bomber, place another blocker. The balloon is red, meaning all Lemmings must reach it.
4. 033. Wheelbarrows of Doom
   Objective: Save 100 Lemmings in 4:00.
   Lower the release rate to 1. Use builders to create a path to the wall, ensuring no Lemmings can reach the
