When you chop through the fallen tree blocking your path, you will open up a road leading to an overlook ahead. A cutscene will trigger in which Juliet reunites with Rosalind. The youngest zombie hunter's bus will be careening out of control in the clearing below you, and you will need to blast it with lightning speed using your Chainsaw Blaster to save her from crashing due to the multitude of zombies clawing at the roof. Shoot the zombies of of the froof of the bus; there will be nine in total. When your blaster reticule turns red, you have one in your sights. If you run out of ammo in the middle of this sequence, head to either side to pick up more ammo. Jump down when the deed is done and Rosalind will go careening into the next area, leaving you to fend off the ten zombies that will spawn.
As the massive group of zombies rises up in front of you, note that you can score multiple kills in quick succession here for great Sparkle Hunting bonuses. Activate your Special if you have it, so that way you can chop apart all of the zombies in one or two swipes. If you don't have the meter filled yet, use your Chainsaw Blaster and quickly feather the targeting buttons to rack up kills in quick succession, another way to get massive Sparkle Hunting bonuses. Kill all of the ten zombies and, while you wait for the next group of enemies to spawn, head up and to the left to find a barn full of Chainsaw Blaster ammo. Hack through the thin wooden walls and run into the barn to pick up more ammo.
By now, a second group of ten zombies should have spawned from the ground. Run back out into the middle of the area and again, either use your Chainsaw Blaster again and again in quick succession or activate your Special to decapitate enemies in groups, thus earning bonuses for Sparkle Hunting. Chop apart those who you can't kill in flashy fashion, and you'll be through with this large group of enemies in no time. When all of the enemies are gone, a headless body will pop out of the ground just begging for Nick's head to be plopped on.
Run up and stick Nick's head on the corpse, and then follow all of the button prompts to ensure that Nick gets up to the large rock ahead safely. When you reach the rock, you won't be in the clear just yet. You will have to perform a sort of celebration dance before Nick sends Juliet flying over the barrier. When you land, look to the left for a lollipop before emerging to take on the eight enemies in the area. Kill them all, being careful of the bomb zombies (taking them out at a distance using your Chainsaw Blaster is perhaps the best way to deal with them.) When all of the enemies are gone, search the back left corner for a stockpile of coins, and the back right corner for a special lollipop. If you need any more healing, another regular lollipop will await you in the right-hand corner where you originally landed.
After you've killed the first eight zombies, a massive foe named Mark will burst from the barn nearby and attack. As with all named zombies, Mark will be tougher and stronger than your standard enemies. He won't be too hard to kill, though, as long as you can keep him stunned. If you can't stun him, dodging over his attacks and attacking him from behind will suffice. After he dies, grab the coins that he drops and proceed to his body to initiate another Nick minigame. Mash the buttons in time with the prompts to send Nick scouting ahead, opening the path to the next area of the level.
