Alright, as soon as you start you will have a chance for an achievement.
Achievement: I Swear! I Did It By Mistake!
To get this achievement, don't even bother moving. Just take your right analog stick (or whatever you have controlling your camera) and just push it straight down. The camera will move until you can see just under Juliet's skirt. She will likely try to cover herself up. You need to hold that for a moment until the achievement pops. It may take as much as 5-10 seconds.
*Achievement: I Swear! I Did It By Mistake!
After you've gotten your first achievement, run up to the gate ahead and hit the chainsaw attack button at the gate to start cutting. Push the LS down until the gate has been cut, then use the Pom-Pom button to bust the door open.
Just beyond the gate will be two groups of groggy zombies. Go up to them and try to wipe out the groups with one attack each. Doing so will activate the sparkle hunter. Really, this just means that when you kill three or more zombies at the same time or in very rapid succession (like the end of one swing to the beginning of another) then you will get a colorful screen and bonus coins. You'll receive a platinum coin for each zombie after the second that you kill (IE. 1 plat for 3 kills, 2 plats for 4 kills etc.) and the amount of gold coins is the number of zombies killed squared and then times a multiplier based on the zombies killed.
Kill those two groups and any stragglers around. Try to use your pom-poms to make the other zombies groggy and then use them again to herd them together. Once you get a group of three or more together and groggy, swing your chainsaw for another sparkle hunt.
Make your way into the nearby parking lot and around the corner. You'll come to a man screaming for help with a giant SOS sign above his head. This means that he is a savable student. Kill all the zombies (6) before his purple life bar is depleted by the zombies to save him. If you manage to save every student in the game (on a difficulty setting) then you'll get an achievement and the good ending. This group shouldn't be too bad. They should come at you as two groups of three and have very little interest in the student.
Kill them and move onto the nearby bus. Use a pop if your health is low because there is a lollipop to the right of the chopper. Picking one up does not automatically heal you. You need to use it from your inventory to heal. This is the ONLY method of healing (aside from dying) and if your inventory is full when you pick up the pop, it's wasted points. For those of you concerned about points, using a pop doesn't cost you any points at all. There is no harm to using the pops but if you have to use a continue, you do lose points. Don't be afraid to use them.
Climb through the bus, grabbing the pop on the way, and go out the front. Once you are out, hang left like you're headed back to the parking lot to find some more gold medals. Grab those and then go along the side of the building in front of you. Soon, a bus will crash into the nearby wall and some crawling zombies will come out to attack you from the building. Use the Low Attack button (A or X depending on console) to swing at them or hit the dodge button and low attack to execute a powerful drop attack on them. Once they are dead, go over to the bus and hop over it.
On the other side of the bus will be a van with a woman on top. You'll have to rescue her from some zombies. There will be a decent amount of them here but they can't reach the woman so feel free to back off for space if you need it. If you'd like, you can try and make them groggy and go for a sparkle hunt but if it still isn't working right, don't worry too much. It's a little tough to get the hang of the pom-poms. Before going anywhere, check behind the bus in the corner to find a Golden Lollipop on Normal. Now you can hop on the nearby bus.
This bus will crash too and you'll come to a courtyard with a flagpole. On the flagpole will be another student to save. Again, they can't reach the student so take your time and space. If you need to generate space, hit the dodge button followed by the pom-pom attack to push them back. This is great for generating space and if you can line some up, it can make a few groggy zombies at once but it pushes them to the edge of the area (usually) which might be too far for you to get close and finish them before they come to. Watch the right side for a group of zombies dancing near a car. Kill them all and the student will drop down from the flag pole.
Now that he's on the ground, you'll actually have to defend him. You'll be attacked by a small group of zombies as he approaches the gate. Kill the specified number of zombies (in the lower left corner) to continue on. On the other side of the gate, you'll be prompted to use your special meter. This will boost your damage to an insane amount. At the moment, this will allow you to kill any zombie in a single hit. Try to make liberal use of this any time you find yourself in a large group of zombies. It makes it very easy to go on Sparkle Spree.
You should make short work of the zombies. Clean up any stragglers and you'll be nearly run over by a van. Be ready to hit the dodge button when prompted. After that, another group of zombies will attack. You'll have to protect the student until he climbs up on the bus. Kill the zombies and save the student.
You'll watch a cutscene and answer the phone. You can't ever actually answer the phone. When it looks like you have a call, it's just informing you that you have a new voice mail. You can check it by going through Juliet's Stash in the pause menu. You should get every phone message just by completing the game. At the end, any missing messages are unlocked.
*Achievement: Life Guard
Once you regain control, you'll be near a terminal called Chop2Shop. Check it out and it will let you buy all sorts of goodies including items that increase your maximum health or strength, lollipops that restore health, special moves, collectibles and new outfits for Juliet. Right now, your options will be pretty limited. Pick up a special move (Chainsaw Stab is best) and the Magic Beans if you can afford them. Leave the shop and head through the doors.
You'll enter a narrow alley with seven zombies though two of them you can't see yet. Kill those as they come to you and make sure to kill one of them with the Chainsaw stab for an achievement! Now turn the corner to find the last two. Kill them. When you play through this level the next time, you'll find a named zombie in this alley. Unfortunately, you HAVE to do a second playthrough of this level to get Mikaela. Hop up on the wooden boxes in front of you and then take a sharp right. Go behind the fence to find a Golden Pop. Grab the medals and the pop, then continue along the brown boxes. Jump off.
*Achievement: Zombie Hunter Apprentice
Run up the alley and out onto the street. You'll be attacked by a bunch of greasers on a long street. You have some good potential for lots of Sparkle if you are careful. Try and capitalize if you can. After you clear the first group, a second and more aggressive group will appear. Kill them too. Make use of the long street if you need to. After they are dead, make your way up the street to the end. There is a Golden Lollipop on this side of the barrier on the right IF YOU ARE PLAYING HARD. Half the Golden pops only appear on hard and half only appear on normal (requiring two playthroughs to get them all). Slide under the barrier.
You'll find the pilots from the chopper shooting at some zombies. You'll also find your first named zombie, George. He doesn't have any special abilities but he is tougher and faster than a normal zombie.
When these three zombies are dead, you'll have to fight the Hazmat trio. They are pretty tough and will never be made groggy. Use lots of dodging and swing the chainsaw like crazy. Be careful of Jerry because that propane tank hurts and he'll throw it at you causing it to explode. Leapfrogging can be pretty helpful because it can interrupt their attacks AND put you behind them for a good attack. Dodge and swing twice (use your judgement), then dodge again. Once these guys are dead, go through the gate and towards the bench in the distance.
