There are three enemies in this room but they are all occupied. Move up the right side of the room and along the wall, you'll find a Golden Lollipop on normal. Grab that and then start attacking the zombies. Most of the zombies aren't anything special but you need to watch for the zombies with the backpacks because they'll throw Molotov Cocktails at you. Kill the first group of three and 6 more will appear. Thankfully only one of them will have a backpack but you will have to protect a student. Kill them, going for Sparkle Hunts if you can. Take him out first and you should be fine. Hop in the elevator when it arrives.
You'll automatically end up in a Pac-Man like game. Cut through the words to begin. There will be some rather large heads trying to eat you. They won't be too aggressive if they don't see you. Your goal is to make it around the board and collect the eight key pieces. Collecting the stars wouldn't be bad either because those will fill your special gauge and allow you to use your gauge to fight the heads if they find you. Once you have all of the keys, head up the back and slice through the Exit sign.
You'll be back in a normal room by a shopping terminal. Shop if you'd like, then make your way through the "S" shaped room. There will be six zombies total and two of them will have a backpack. It might be best to kill them first and then maybe go for a Sparkle Hunt on the rest. Once you've killed them all, stick Nick's head on the cheerleader body to launch to the upper level. On the top level, walk around the outside and grab the medals. Drop down and fight the two zombies here. They are quite easy to kill since they are alone and distracted. This will save two students. Get the rest of the medals and drop to the lower floor. Get into the nearby game.
You'll have to climb to the top of the building by taking the elevators. Pink doors will take you places (to other pink doors) and elevators will lift you up and down. Go all the way right, take the elevator up one floor. Go through the pink door and then up the next elevator. The lights will go out on the next floor. Kill the zombies and head right to the elevator. This elevator will go down and all you to access a door while you are still on the elevator. Go through the door and then get on the elevator to the left.
On this level, you'll have to walk across the zombies to the far side. Go up the elevator one level . Head far left to the blocks of Nick's head. This will make a body appear on the floor above. Take the door on this level to the level above to attach Nick's head. Now take Nick's body to open that wall. Follow him down with Juliet and then take the elevator up to the top. Go across and take the elevator up a level. You'll get Nomed and have to saw through to get free. Take the elevator on the left side to get out.
You'll find yourself in a sort of disco room. Try not to use the pole immediately because they take too long getting on stage so you don't have as good of a chance at killing them all. Kill this first wave slowly. A second wave will appear and now would be a good time to try and get some Sparkle Hunting done. Use the round edges to climb zombies together. After this group, one last wave will appear and one of the zombies will have a boom box. You want to kill him first because he makes the other zombies stronger. Once he's dead, get some Sparkle and then move to the next arcade game.
This arcade game is pong. You'll have to fight off a couple of simple waves of zombies while dodging the white ball that bounces back and forth. After a few waves, the pong ball will slip by and hit the barrier behind the other paddle. Go behind that wall and take a sharp left to find a lollipop. Now leave.
There's a shop on the roof if you want to shop. If you go around the side of the elevator you just came out of, you'll find a Nick Ticket. Soon, greasers will start dropping out of the sky. Accompanying them will be backpack zombies. I would take out the backpacks first but watch out for the greaser zombies to block your attack. They'll come out in groups of three for the most part so it's not going to be too easy getting Sparkles. Once 10 are dead, a Boom Box zombie named Wesley will appear. Kill him quickly and then clean up the zombies that appear. They will basically be the same group you just fought. When they are dead, the chopper will nearly crash into you. You'll have to shoot it out of the sky. Collect the medals and use the arcade game on the roof to leave.
This game sees you trying to ascend a tower without getting knocked off. You CAN shoot but there's an achievement for NOT shooting. Go all the way up, slide left and go up again. There will be three open windows going right. Slide to the end and wait for the zombie to attack. Wait for it to pass and then go right, up two, and then left. From here, slide all the way up and left to avoid the large falling object.
Another zombie will be dropping bombs down the middle lane. Go up and wait for one to pass, then slide left. Watch out for the blue UFO that will stop where you are and try to drop something on you. Make sure to watch out for windows opening because if you are on one when they open, it will knock you off. Move up the right side and then dodge left as soon as you can to avoid the two falling bombs. Wait for them to pass, the move up and dodge left again. When you get there, immediately move to the left as another zombie drops bombs right down the middle. Move around him and you'll come to a couple of black UFOs sliding back and forth. You want to go up and to the left. You can't make it past both UFOs at the same time. Stay on the left most lane to get past the two UFOs and wait for the giant car to slide past you.
Once the giant car has passed, slide all the way right and go up to the spot where the zombie is. Wait for another car to drop and slide left. Go up a little and watch for the next UFO. Move up the second lane over from the left until the UFO drops the cow. Then slide left. Up ahead, you can see a little triangle that's going to drop as you move up. You want to move right, up and then right again to get around the open windows as it falls. You want to slide as far to the right here as you can to avoid the larger two lane object but watch out for the bombs that are dropping down this column.
Make your way beyond that two lane object. You'll have to move up only three lanes now and they will all be dropping bombs so you'll just have to dodge side to side as you move up. Thankfully, it's spaced out so it's not too bad. Just make sure not to go too fast because you'll get hit by the black UFOs. Get to the last two which are going to force you up the middle. At the end, you'll find a bunch of rows of windows that open and close. You'll have to time when you leave. Don't try to rush across because you won't make it. Stay just below the windows, wait for the row directly in front of you to open. As soon as it closes, start going up and you should have no problem making it to the end before they reopen. Just keep climbing to the top to get out.
*Achievement: No F ear of Heights.
Back on the roof, you'll find a shop and a springboard. Shop if you want, then use the springboard to launch yourself up to a lollipop, grab it and any medals you earned. Hop down and collect the medals here and then wander around the outside until you can get into the dome in the middle.
Josey
Josey will start on his little saucer and you'll have to shoot him. He'll hover around, try to ram you occasionally and then shoot little lasers at you. These lasers will start on one side and the move to the other so just jump over them and keep shooting. When you run low on ammo, a bunch of holographic stairs will appear around the outside of the room. Climb them to get ammo and then from the top, shoot at Josey. Just watch out for the bombs that he drops and keep moving every so often. If you ever knock the saucer onto the ground, you can attempt to chainsaw him but it's easier to just shoot him because he's only down for a very short period and once he's back up, he's going to ram you. As soon as him health hits zero, the "Finish" will automatically initiate.
The next part of the fight will be on the outside of a UFO. Josey will be inside of a red energy shield in the middle which will send energy to the pylons around the outside of the ship. You need to destroy those pylons. Hit them while they are blue and watch the energy as it moves around the ship towards you so you know when to get away from it. After you destroy a pylon or two, a couple of gold floating heads will appear. If they are near the pylon when it becomes energized, they'll become energized too. When they do, they'll charge you. Destroy all the pylons but don't immediately go up to finish him just yet. There's an achievement for finishing him in the last 10 seconds. Wait until the timer is close and then saw through for the achievement.
*Achievement: Critical UFO finish
*Achievement: Disco's Dead
