Theory 1: Alright guys! Apart from the stops we saw in the trailer I suspect TWO additional stops that were not revealed. Here's why!

On the pieced together map posted, you can see the last stop shown has more path extending out, ending on what is obviously some kind of town or complex. Then more path loops out of THAT and is primarily out of sight from what we've seen so far. I suspect another stop just outside of our view in the map to the west. I think THIS one will have the current treyarch twitter pic as its map mark, because it depicts some kind of mountain formation.

Theory 2: My friend told me what he did but he didn't have any proof so I didn't believe him. I didn't have time to try this so maybe you guys can try it and see if it works. Again I am not sure if this is legit or not so I'm sorry if it wasted your time trying.
Items you want to acquire before you begin:
EMP Grenade
Jet Gun


Steps:
Get on the bus and go to the part in the video where the sandbags and broken car are blocking (2:32)
Toss an EMP grenade to the bus driver and make sure the bus stops BEFORE the sandbags.
Hop out and pull out your jet gun and fire it at the debris.
The debris should clear.
Get back in the bus and when the bus re-activates, it should go to the right where you just cleared.

Once again, I apologize if this doesn't work.
When I have time, I will try this and confirm if it works.

1. THE DLC: it is widely believed that a new expansion will be available on tranzit for those who purchase the DLC packs, so that the players may start out at the bus depo and travel through the DLC packs instead of the green run map

2. SECOND BUS: in the picture at the start of the tranzit game type, you see the regular bus in the center of the frame, but if you look to the far right of the screen, you can see a sliver of what appears to be a double decker bus. This, the 2 quotes the bus driver makes about upgrading to first class and its double decker class, as well as the seconed texture pack for a bus driver in the PC files leads many to believe that there is a hidden part of the map only accesable through this second bus.

3. BUS TRAIN: this theory has been bunked. It states that due to the unique train-shaped grill that you attach to the front of the bus, you can set the bus driver to access a secret underground railroad facility that leads to an entire underground city. This was widely believed due to the bus driver's "Mt. Weather" quoute, mount weather being a government facility that has an entire underground city capable of housing aprx. 2000 residents along with roads and a "tranzit" system. This was bunked due to people glitching under the map and finding nothing.

4. NAV CARD: this states that under certain conditions, a nav card can be added to the bus driver's software to force him to take a new rout, which would either be a different map as stated in theory #2, or would mearly change the drivers movement and departure times.

These are some of the most-popular tranzit theories that actually have some merit to back them up, if you have any questions then feel free to post them.

1. 2ND POWER DOOR: because of the versitile use of the galviknuckles and the wind generator, there is thought to be a hidden door or part of the easter egg which requires these devices (similar to the door leading to pack-a-punch), concidering that 3ark has never added anything to a map that wasn't needed for an easter egg.

2. POWER SYMBOL ON THE TRAIN: if you travel the map, you can eventually find a railroad with a destroyed train on it. I've heard that there is a power symbol hidden on one of the train cars.

3. CHURCH BELLS: many players are able to get the church bells to ring via explosives and other means. this is thought to be intentional and part of the easter egg.

1. This is Treyarch's most ambitious map to date and the last easter eggs gave all 8 perks or a weapon so this one should be on the same level;

2. On twitter Jimmy Zielinski said two things to think about: When NGT Zombies tweeted at him that he was about to blow the lid on Tranzit Jimmy said, "Not necessarily" and another cryptic tweet from him said, "Seriously, some of you are making great progress, keep it up! The rest of you might want to run faster. And no, I will never tell." I take this to mean that those of us who have completed the Tower of Babble achievement have made progress but aren't done. The rest of us running faster I take to mean that we need to catch up if we want to get to the point in the storyline that those who have completed are at. And he will never tell whether there is more or if that's it, we have to figure it out;

3. There is still the navcard to figure out, that door in the research facility with a green lightning bolt on it still hasn't been opened (as far as I know), and we still haven't figured out anything to do with the lightning trap.

4. Once you complete the easter egg the table with the 115 meteorite on it stays in the cornfield, indicating you have completed the first part and there is still more to do on subsequent playings of zombies.

5. In this map many of the zombies are mental patients and if you look at the uniforms of the non mental patients the patches on the arms say Hanford Sanitarium. There is no sanitarium on this map although there is Nacht der Untoten in the corn maze so maybe this is a tip of the cap to Verruckt... could Verruckt be hiding somewhere on this map as well? I doubt it but we're dealing with the most secretive faction at Treyarch. Because of this detail I believe we are missing something.

6. Upon completion of the easter egg you don't even unlock a gamer picture. They simply wouldn't do this to us. Think about "Cryogenic Sleep" the pre easter-egg achievement, could Tower of Babble be the pre-easter-egg achievement in tran

7. On the map of Green Run there is a building in the lower left which is unaccessible. They put "Five" as a hidden map on Black Ops 1, why shouldn't we assume there is a hidden map on Black Ops 2 as well?

8. There is no wonder weapon on Tranzit which makes you wonder if we simply haven't gotten to that point yet.

9. I will admit that Tranzit is an impressive map, but this can't be all that the Zombie Labs portion of Treyarch have been working on for the past year or so. We expect better from them, and they expect better from themselves.

10. Last of all, we were told this was going to be a campaign-type mode for zombies, and it wouldn't be very fun if the campaign ended right here or very campaign-ish.

Proven:
1. Aiming at the handle at the laundromat creates 4 Beams of light, one leads to the top of the bank, the laundromat door handle, random spot it the rain forest cafe, and the other beam is unconfirmed as to where it goes, but it appears to head toward farm but stops short (these beams appear to be useless thus far, could just be a lighting glitch with the tower or could be part of a later part of the Easter egg)

Disproven:
1. Throwing a Semtex at the two sun clocks and one moon clock at the same time (only a visual effect from grenade, making the numbers and hands on the clock appear to disappear when they don't)
2. Using the Jet Gun on all the clocks in one game (does nothing)
3. Powering up the computers and electric boxes found in power room (does nothing)
4. Activating the TV in the farm does not make this rock with a power symbol appear in the lava by diner that is said to be seen by Samuel (couldn't find it even with a sniper)
5. EMPing, using a turbine, or using the jet gun on the laundromat does not make the door open
6. Reflecting the the rays with a zombie shield (goes straight through it)
7. EMPing, using a turbine, or using the jet gun on the railroad doors (appears to have no affect)
8. EMPing the bus on the bridge (nothing happens)
9. EMPing, using the turbine, and using the jet gun on the church (has no affect)
10. Shooting the golden pipes on water tower with sniper, upgraded sniper and upgraded ray gun and upgraded RPG (does nothing)
11. Puting a turbine at the pylon and the street lights to link the moarse code (nothing happened)
12. Using all 4 navcards on the Obelisk at the exact same time (still incorrect navcard)
13. Shooting the top of the pylon with an rpg
14. Throw an EMP at every lamp post even the ones that don't glow green (nothing again)
15. Interact with clocks and dart board (with x, didn't seem to do anything however a friend claimed to hear something upon hitting x while jumping to hit the clock in the diner, but I could not replicate what he stated)
16. Interact with the axe or fireplace at the shack
17. Put down a turbine at the shack
18. Shoot an RPG into fireplace of shack

Not Yet Tested:
1. EMPing the bus to find the navcard under the seat
2. EMPing the bus to allow the beams to hit the bus
3. EMPing the bus underneath the stop light and messing with the stop light
4. Looking for "egg" like object that appears when meteorite was (only seen by merlton) and then blows up in a static like discharge, which also makes the teleporters give off this same big ball of electrostatic discharge
5. EMPing the box upon getting the light beam to shoot from it
6. Throwing an EMP at every leg of the pylon at the same time
7. Turn the power on and off consecutively for a long time
8. EMPing, using a turbine or jet gun on the rod looking thing in the lava by diner
9. Use porters X2 on the day x/2 me sign
10. Throw a monkey bomb in the shack with monkey skulls everywhere
10. Plus much more...

Zombie Story Line Cod: 5 Waw - Bo2

Disclaimer and Side Notes: I do not own Nazi Zombies or Treyarchs' COD franchise. Also keep into consideration I might be wrong on a few things, 99.9% of this is true.

Der Reise:
Dr. Maxis and Edward Rictofen were two Nazi scientist who dedicated their lives for finding a solution for the perfect super soldier. During times of failure they seemed distraught and highly stressed, but Maxis would not give up so easily. He created the group 'Ascension 935'. This group was made up of both Nazi and Russian scientist who worked together in Der Reise to create the said super soldier. As the years went on, Maxis and Rictofen created the DG weapon series. DG stands for Die Glock which in english means The Giant. Maxis created the DG-1 or otherwise known as the Ray Gun, while Rictofen created the DG-2 (Wunderwaffe), DG-3 (ThunderGun), DG-4 (Winters Howl), and the Monkey Bombs. The two tested their creations on captured American soldiers, but the weapons seemed to have no effect. Claiming the weapons a failure they continued with their super soldier research. One day while working on a serum to inject in a American soldier, sighting of tiny glowing red meteorites were heard all over. Maxis and Rictofen rushed to get their hands on the meteorite and when they did, they named it Ununpentium or Element 115. They decided to use this element in their super soldier serum, but when they did they created something far more fierce. The first zombie. Radios spread out all over the Der Reise map pack allow you to hear Maxis as he tries to control the zombie, but soon it grows hungry and attacks. The put it down and Maxis wants to try to make another. They then create teleporters around the facility so they can easily bring zombies back and forth from labs and testing chambers. Soon they even realize that they could add 115 to their DG series and that it only works on the zombies. Once the teleporters are complete and the zombies are now being frequently created, things start getting a little crazy. Maxis is manic now for he is at a time crunch for perfecting a super soldier. He gets Samathas' dog (fluffly(By the way Samatha is Maxis' daughter)) and throws it in the teleporter. When using the 115 in the teleporter and about to teleport Fluffy Samatha walks in the room and sees that madness. In all the confusion both Samatha, Fluffly, and Maxis end up being inside the teleporter. Rictofen took this chance and closed the door. As Maxis screamed from the other side Rictofen activated the teleporter and they were whizzed to another section of the facility. When they arrived only fluffy and Samatha seemed different. Samatha was scared and opened the door and ran. As Maxis caught up he told her it wasn't Fluffly anymore. Fluffy was now a zombie AKA hellhound. Fire was engulfed around its body and its eyes yellow. It attacked Maxis and Samantha and that is how Der Reise ended. A few years after all this is when Tank, Nikolai, Takeo, and Rictofen showed up. Rictofen sometimes says things like, 'Oh that damn Maxis-Oops I mean what is this?'. He obviously remembers his times here.

Shi No Numa:
I won't go into much detail about this except that another 935 scientist named Peter was assigned here after working in Verruckt. He is the man with no arm hanging from the ceiling. Some radio messages around the map allow you to hear more of his research and things he has discovered. The reason why zombies appeared here in the first place is because of the big fat 115 meteorite right outside the map.

Verruckt:
Before the Der Reise invaision Maxis had worked here with Rictofen. The two were experimenting on Monkeys and Pigs. They needed to expand their knowledge on brain control and so they moved from here to Kino. A few months afterwards is when Peter showed up and learned everything. He then went crazy and had to fight off some zombies. He was then bitten so he had to cut off his arm, thus why there is a hand on the power switch. After fending for himself for awhile is finally when he was transferred to Shi No Numa.

Nact Der Untoten:
Tank, Harrison, Bill, and Higgens (not official names except for Tank. Me and my friends came up with the other three) were transferred to a Japanese airfield in search for some of the 115 element. An random explosion brought the plane crashing to the ground and when Tank awakens finds himself starring at a sprinting zombie. He and the others retreat into the airfield barricading themselves and seeing different chalk markings of people here before them. They also find some of the element and documents of 935s plans. Although not mentioned in the game Tank and his crew move on towards Verruckt where they learn more and then finally Tank is the only one who makes it out alive. He then moves to Shi No Numa where he meets the three other main characters. Another thing is that once moving from Verruckt the element 115 made Tank lose his memory after Shi No Numa, so as far as he knows he just met Nikolai, Takeo, and Rictofen even though he's known them for a good while.

Kino Der Toten:
After using the teleporter in Der Reise, Tank, Takeo, Nikolai, and Rictofen appear to have traveled through time. They are now in a german movie theatre in 19 something or rather and begin to learn of everything Maxis and Rictofen did here. Rictofen admits at what he has done and the group forgives him. In a radio message to himself he says that he never knew that the MDT (Multi-Dimensional Transporter) was capable of time travel. He also ask where has Samantha run off to for it is obvious she now has the power to control the zombies. As the game progresses throughout the map we learn that this is not just a movie theatre. It is truely a brain washing asylum from Verruckt. After fighting off zombies for days the group decides to leave. Here we also learn that the Nova 6 zombies have been experimented on from within the Pentagon (one of the rooms that you teleport to after using the Pack-A-Punch teleports you into a radio station like room and has a TV with the pentagon on it. Also it has a letter on the floor under the table that says 'keep the gasers in the chamber'). Remember how Rictofen says the MDT is capable of time travel? Well you do realize after pack-a-punching that it takes you to different rooms? I thought those were in the theatre, but it turns out that one room is Samathas' room when she was un-zombified and the other is when she was. Another room is from when the theatre was used as the medical facility for brain control (hence the doctor chair and screams).

Kino Der Toten (Secrets & Details):
The Nova Six gas zombies are created when Rictofen decided to mix 115 with Nova on monkeys. In result it made N6Gasers. Spread throughout the the stage are containers holding the N6Gasers and in one corner we see a container open with nothing inside. We also see a blood line from the container to the teleporter meaning that over the course of their time travel that the zombies once again broke out. We also get to go through different rooms seeing Samathas room with a Monkey Bomb as a present from Rictofen (in secret he really misses her), her room when her zombiefied self took over, a room from the Pentagon level 'Five', and then a room from Verruckt itself.

Five:
This is basically an easter egg zombie map just thrown in because of the tim setting of Black Ops. It plays very little in the story, but we do know that group 935 had ties with the government in creating the zombies. On this map in the very bottom level are the gas chambers where they experimented the nova gas on monkeys and pigs. This is how we know they were created.

Ascension:
Now this is the brand new map and one of the hardest yet coolest ones out there. Here we see everyone except Rictofen all beat up. Rictofen is wearing a cosmodrone space suit with a illunamati sign on it. He makes a remark that his clothes were to disgusting for him to wear. They are descending from a Space Lander used to go from one area to another on the map. As they land a man named Doctor Gersch talks to them from another dimension. He warns them about the danger they had stepped in coming here and says 'she is coming. Help me', of course we know he is reffering to Samatha. As the group battles through they learn more about Gersch and his creation of the Gersch device which is a black hole. They then use it to transport a hard drive to a junkyard where they have to do several test to free him from his dimension. Samatha is then heard to growl angrily and then he rewards you with Death Machines for one minute total. People say there is more to this, but we are not sure yet. We also now learn that space monkeys fall down from their lander and attack you and your perks. As it turns out the moon is housing the 115 element and when they sent the monkeys into space they got infected and drop back down as the space monkeys. They are attracted to the perks because the perks are made with a filtered substance of 115.

Ascension Secrets!:
The moon (if you look closely) has a space lander lodged into it and also has some element 115 stuck in it. The Space Landers around the map have the initials of NCCP (National Cosmodrone Comuning Plant). Remember that the Cosmic Silverback had the NCCP initials on its jet pack? Meaning that it came from Ascension. If you look around you can actually find a torn up picture of a huge gorilla hugging 3-6 smaller monkeys. This leads me to believe the Cosmic Silverback and 'her' babies were sent up to the moon in a lander and came into contact with the 115. They then took control of the M.O.O.N. facility and the Cosmic Silverback was able to send her babies down to cause us some havoc.

Call of the Dead:
Not much to say about this just that George had ran across some sociopaths work (Rictofens) and accidently upturned some 115. This allowing the dead crew that was originally the crew of Rictofens come back to life. After turning into a steroid crazy zombie himself Danny Trejo, Sarah Michelle-Gellar, Robert Englund, and Micheal Rooker came together to kill the unwanted horde. Meanwhile the MDT was at it again and plopped our four original heroes from Ascension to....here. But apparently it wasn't on accident. Thats what Rictofen wanted them to believe so he could get himself the Illuminati Golden Rod. After that the MDT suddenly seems to 'work' again and your on your way to Paradise.

Shangri-La:
Now there is so much detail in this map that I will make it as generic is possible. Right now my wrist is killing me from typing all of this, but I'll manage. Once teleported here, the three other characters think it is all accident once more. Rictofen now has the possesion of the golden rod. He admits to them that they need to get here, but will not explain to them why. Now if you look around, on the ground beside the MPL is a radio of a explorer. Me and my friend didn't think of it until about the 50th time playing it we heard Rictofen say 'they couldn't have found it yet? Could they?'. He is obviously reffering to the Focusing Stone. After helping them go through all the easter eggs crap that I hated so much we finally bust down the wall and Rictofen screams in pure pleasure...'ITS MINE'. The explorers tell you that they see something else and leave. Now a lot of people think this is the end of the map, but after completing the easter egg and doing about 2-3 more rounds you get bonus dialouge. Tank ask Rictofen so what if he has a rod and rock and Rictofen replies simply 'Where can I find a satillite big enough to transmit my signal?' The focusing Stone is the reason why the utopian people became zombies. It is simply a condensed form of 115. This is leading me to believe Rictofen wants to turn the world into his zombie minions. And the only satillite big enough for the job is...Oh no...THE MOON!!!

Tranzit? : Zombies have blue eyes because Richofen becam the new zombie lord, in black ops one, Samantha was the zombie lord. The planet is earth but the last DLC on BO1 was MOON. After that the zombies were plunged into earth in BO2 which is why Town, Bus depot AND Farm all have lava and cracks in the floor with fire in them. The survivors are basically the soldiers or CIA that were sent to investigate the area of zombies. They had a breach and barely survived.
