So you start out in a small room surrounded by about five or six zombies. Run around and knife all of them to death. Have one person guard the windows and fend off the zombies while somebody else builds the Turbine. Apart from your guns, the Turbine is your most valuable weapon and a key piece to surviving. Scour the room for the three parts to build the Turbine. Grab a part, bring it to the blueprint and build it, go get another part and repeat until you have the Turbine built. Once you have it built, make sure everyone in your match has one, and it's time to leave. Rather than paying 750 points and buying the door to get outside, put your Turbine to use and get out for free. Place your Turbine in front of the side door, and it will open for you. Make sure everyone is in the little room you just opened, then pick up your Turbine and go in. Scour this room for parts. You may find a ladder in here, or a bumper that looks like it goes on a train, which you can build onto your bus. You and your friends get all the parts you can, then open the door in front of you with a Turbine and leave. Make sure you grab your Turbine. Run around the outside of the Bus Stop, killing zombies and building barriers for points. If you have a ladder or an upgraded bumper, go build it onto the bus. The bumper can be built onto the front and the ladder on the back-left corner. The ladder lets you get on top of the bus from the outside while the bumper takes out zombies that stand in your way, preventing them from climbing in your windshield. When you here the bus honk, get on. When everyone's on, close the doors. Go to the back of the bus and look at the ceiling. Buy the B23R, an overpowered three round burst pistol. Make sure to conserve it's ammo as much as possible.

The B23R and upgraded bumper.
Stay on the bus until it stops, then get off. You are now at the diner. Towards the back of this stop, there is a shed that you can open via the Turbine. Go back and do so, scour the shed for parts, grab your turbine and get out. If you have a lot of points, open the door to the building with the mystery box, and let everybody have a chance at the box. Though I do not recommend it, the Zombie Shield can be built in here, if you wish. Kill the rest of the zombies. When the bus honks get on and leave.

Move it, driver!
Keep riding until you stop. Make sure you keep the bus well protected, as zombies will try to break in through the windows. Once you stop get off. You are now at Farm. This stop may not look like much, but if you open up that gate, you will find yourself at a farm. If you decide to buy the gate, you can buy the Remington 870 MCS off the wall in the barn and Claymores in the shed. Inside the house, you will find parts to build the Turret. But my reccomendation is to not even buy the gate hold onto your points, trying to survive the best you can in the little muddy area. Once the bus honks, get on and leave. Stay on the bus until you stop at the Power Station. Now, you have a lot of stuff to get done at this stop, so if your planning on doing everything you need to and still catching the bus before it leaves you behind, you'd better hurry!
Start by running over to the little outhouse-looking building. If you don't already have a weapon you are comfortable with besides your B23R, buy the AK74u on the side of the building in exchange for your M1911. Have somebody buy the door to the outhouse thing, and go in. You fall down into a brightly-lit power room. Whoa! Not what you expected, huh??? In here, you will build the Power Machine so you can turn on the power. Find the generator, the switch, and a mangled up zombie hand that can be found lying somewhere on the floor in the middle room. Build everything, then turn on the power. The door to your left will open up about 15-30 seconds after turning on the power, but if you want to get out faster, use your Turbine to open the door. Grab it and run up the steps. You will now find yourself on a catwalk above some lava. Make sure not to fall in while running along the catwalk. The Electric Trap can be built in here, but don't even worry about it. Buy the Tombstone perk-a-cola if you can (it gives you all your perks and guns back when you die), find the opening in the building, and jump down so you land in front of the bus. Now you are stuck and it seems as if you will not be able to board the bus, but you still can, using one of two ways. If you have the ladder built onto your bus, go around and climb it, jump off the other side of the bus, and you are good to get on. Or, you can just sit and wait for the bus to start moving, and then just jump on it while it is moving. Whatever the case, get on and head to the next stop.

DO NOT allow your bus to be breached! Keep those windows boarded up!

Welcome to Town.
When the dust settles and you finally stop, you have made it to Town. Now, if it wasn't for the fact that there are no wall guns here, you could probably just stay at this stop forever and survive for ages. But sadly, you'll eventually run out of ammo, and then you will be stuck at a stop with no bus, no ammo, nowhere to get any ammo, and hoards of zombies coming for you, and then you'll be screwed, so you can't stay here, like it or not. So when you get off the bus, you'll be once again trapped by mounds of debris, forcing somebody to open the door to the bank. Run through the bank, exit it and turn right. Watch out for lava, then find a set of stairs with a buyable door at the top. Buy it, then go in and buy the Juggernog perk-a-cola. If you go back in the bank, you will see a safe against the back wall. Throw one grenade at it, and it will open. Run inside, turn right, and you'll see another safe blocking your path. This one requires two grenades in order to be blown open. Once you blow through that, you'll find a wall with a green button with a lightning bolt on it. Now, if you remember, there was a similar button back at the Power Station, just as you drop into the power room. Now, what you have to do to access it is very difficult and somewhat complicated, and by now it's probably around round 8 anyway, making it even more difficult, since zombies will now start getting tougher and spawning in bigger groups. You have to have one person in the power room at the Power Station by the green button, and another in the safe by the green button. Each of you place your Turbine by each green button, and after a second both walls will raise and you will come to a narrow room where you can build the Pack-a-Punch machine AND it can get you back and forth between the Power Station and Town without the bus or running through the smoke and getting your eyeballs scratched out by Denizens, annoying little wastes of flesh that pop out of the ground and jump in your face scratching you when you run into the smoke. So if you can pull this stunt off, you have made the Pack-a-Punch machine available and linked two stops, and keep in mind, there is a gun at the Power Station, the AK74u, so if you can link the stops you don't need to worry about running out of ammo when staying in Town without the bus, because you can always go back to the Power Station whenever you need to and buy more ammo. But like I said before, if you don't link the stops, then you can't really stay at Town without the Bus because you will run out of ammo and get into serious trouble. So if you linked the stops, hang out at Town for a while. Hope on the Bus and buy some B23R ammo before it leaves. If you have not linked the stops, when you hear the bus honk, run through the bank, get on the bus, and leave.

When you stop, you'll find yourself back at the Bus Station. This is not a good stop to stay at, so survive and leave ASAP. I must warn you, there will be a zombie boss coming before long. Though turning on the power reaked benefits, it also let loose the Him, an electric zombie boss that chases and shocks you. You can keep shooting and knifing the him until he goes away, but he will be gone just temporarily. If you wanna kill him permenently, you can either throw an EMP Grenade at him and that will take him out, or if you have the Galvaknuckles equipped, you can hit him twice them and he'll die, too. If you try to just get on the bus and leave, abandoning the Him, he will come after you. He will latch onto the side of your bus, shocking you and the bus driver. When Him shcoks the bus driver, it will knock the driver out for a second, then he'll pick his head up and keep driving. Your next stop is the Diner once again, and this is a decent stop to stay at due to it's medium size and the mystery box being there, but if someone would happen to get the Teddy Bear out of the box, they'd be stuck at the Diner with slim chance of survival. So you probably don't wanna stay here, either. Next, you'll come to Farm. Not a good stop to stay at, because the only gun here is the Remington 870 MCS, and that gun is not very powerful in the higher rounds. My reccomendation is finding a permanent stop to stay at and riding it out, seeing how long you can survive, but the first three stops are no good to stay at. The fourth and fifth stops, the Power Station and Town, are not good permanent stops either by themselves, but those two together, linked up are the perfect permanent camp. So my reccomendation is when you come to the Power Station for the second time, have two guys stay at the station, and everybody else you have go over to Town. Do not kill all the zombies, but make a few crawlers by using a grenade to blow the legs off some zombies. DO NOT KILL THE CRAWLERS!!! Leave them crawling around. Send someone over to Town to help you link stops. Keep the zombies away from your Turbine, as they will destroy it if they have the chance. While you still have crawlers out each of you put down a Turbine by each green button while not letting the crawlers near the Turbine. Once you've got the stops linked, build the Pack-a-Punch machine, build some barriers back up, pack some guns, buy some ammo, get all loaded up and ready for the upcoming round, and when you're all locked and loaded, go ahead and kill the remaining crawlers. Now you don't need to worry about the bus or anything. Your loaded down at Town and the Power Station, so now simply do what's neccessary to survive as long as possible.
