Lollipop Chainsaw Walkthrough: All-American High School Part 4
Run down the alley once you have dispatched all of the zombies in the area. Turn to the left after passing the traffic cones and turn around and collect the coins in the corner. When you've nagged them all, head over to the pipes and saw through the one in the front. Head through the pipes and go forward. Run down the stairs to the right and turn right into the street. As you run ahead, a large group of zombies will burst from the windows to the left. Hack through the zombies with your chainsaw. You will have to kill a total of twenty-six of the enemies. Luckily all of the enemies here will be of the basic zombie variety.
After slaying the basic zombies, one of two things can happen. If you are playing on one of the harder difficulties, a named version of one of the dancing zombies that normally appear later on in the game will emerge to challenge you. Use your dodge move to get behind the zombie and strike it with your pom-poms to stun it before swiping away with the chainsaw. Repeat this tactic until the enemy falls. If you are playing on Normal, the area will simply be cleared and you can proceed onwards.
As you approach the gate ahead, a short cutscene will show two cops desperately trying to fend off the approaching zombies. Rush in before the gate closes. Three zombies will await you by the flaming wreckage of the helicopter, one of whom will be the named helicopter pilot. Kill the two weaker enemies first before focusing on the helicopter pilot. Dodge away from his attacks when he winds his arm, and strike him with your chainsaw from behind. Grab the coins as they spurt from the corpse. After killing these three enemies, a tank of propane will fall down into the arena, followed by three hazmat zombies. These creatures will be much tougher than the standard fare, and the one armed with the propane tank will slowly swing away with his weapon, which will deal heavy damage if it can hit you. Take special care to avoid this zombie, while slicing up the rest. Focus on him last.
When these enemies are dead, you can go ahead and proceed through the rest of the level.
