I HAVE UPDATED THIS TOPIC. If you read it before try reading it again as I improved some ideas

I have been working on this for the past 2 days. It is EXTREMELY long but it is also worth the read.
I'm not gonna get this copyrighted since I wish Treyarch would use it even without anything in return .
The special thing about this map that I included was needing to do some steps to reach certain rooms.
If you have any thing you would like to change or add to the map I would gladly add it to this topic if it is a nice idea.

Name : Spielzeit (Play Time)

General Idea of the map : This map is a carnival which was built over a secret 935 facility in Australia, after Dr. Maxis was killed. Thus, it was never destroyed by Dr. Maxis with the nukes since he never knew about it. Before the zombie apocalypse, the carnival was a real one used to distract the people from noticing the secret facility. The map consists of 2 parts : The carnival part and the underground secret facility part. The secret facility part consists of 2 rooms only, but they are HUGE (each is as big as the biodome). To reach it you need to activate a secret teleporter (will explain later). The first room in the carnival part of the map has a mainframe which could receive anyone using ANY teleporter. It looked like decoration on the floor, so no one suspected what it was. The 4 characters reach this place without actually intending to (will explain later), and they want to finish what Dr. Maxis started (killing ALL zombies that were left on earth), although they also want to know more about the secrets behind Richtofen's researches and the ways he used to control the zombies, so that they can stop him, for good.

Zombie Types :
In the carnival : Civilian zombies (females included) and security zombies.
In the underground facility : Scientist zombies and the all-time favorites : Nazi zombies (although the facility is in Australia, but Nazis from Group 935 were the ones to create it and work in it).

Characters : Samantha (in Richtofen's body), Nikolai, Dempsey, and Takeo.

Rooms :

-Starting Room : The outside on the moon (place with teleporter). You cannot return to this room. Samantha in Richtofen's body would have a ray gun with 0 ammo, Takeo would have a pack a punched MP5K with 0 ammo, Dempsey would have a dual pack a punched zap gun with 1 ammo, and Nikolai would have a M&S with 0 ammo. All players have only 10 seconds to use the teleporter, as hundreds of zombies led by the Astronaut Man come towards them running. This room is just to make the map awesomer and continue the story. The ammo left with Dempsey cannot be used until they all step on the teleporter. A zombie grabs him and he shoots it while being teleported, thus a teleporting malfunction occurs because of the electric charge, taking them to the wrong mainframe. After teleporting, you reach the first room in the new map.

-Arcade Room : You reach this room after teleporting, still with the weapons that have 0 ammo. The characters are still wearing their space suits, but take off the helmets as soon as they land. There are three wall weapons in this room, the M1911, the olympia, and the M14. The M1911 costs 0 points to buy, and instantly swaps with the 0 ammo weapon you're holding. The other wall weapons do the same, too. This means that the weapon with 0 ammo you're holding would disappear as if swapped, instead of getting another weapon. Even if a person chooses to keep this 0 ammo weapon and receives a max ammo the weapon's ammo won't be filled. The quick revive is found here. This room has many arcade games spread all around, thus the mainframe looks like a decoration added to the room. There are 3 barriers, and 1 hole that the zombies will make in the wall (like in the first room in five) thus making it a fourth barrier. 2 doors are found. Each costs 750 points. 1 leads to the Bathroom and 1 leads to the Purchase Room.
Size : Medium

-The Bathroom : It has one opening in the ceiling from which zombies come. It contains the MPL. It is a tight room with 1 door that costs 1000 points and that leads to the Food Court outside. It has the new perk-a-cola "Under-cover" (will explain later).
Size : Small

-The Purchase Room : This is the room from which tickets used to be purchased and games sold. It has the PM63. Some carts are found in this room with tickets and toys on them. It has a debris that should be cleared for 1000 points. This debris consists of torn toys and gifts which are covered in blood. There are stairs that take you underground to the Tunnel of Love. It has the new perk-a-cola "Slashee" (will explain later).
Size : Small

-The Food Court : This room consists of many food carts such as hot dog carts (some flipped over, some covered with blood, and some broken in two). It has fences all around and grass on the ground. Zombies spawn from the ground like call of the dead, or climb over the fences. An MP40 is found in this room. The fences have a large wooden door which leads to the Games Area. It could be opened for 1250 points. It also has speed cola. It has 1 turret on a hot dog stand.
Size : Medium

-The Tunnel of Love : This is mainly a dark, large, square room underground with a small canoe on one side that's on a river in a tunnel. It has many ripped heart shaped decorations, and some romantic music that actually gets you scared from the place. There are 3 barriers over there. It contains PhD flopper, claymores, and an MP5K. You can ride the canoe for 500 points. Only two players could ride it at once. It leads to the Games Area, with an approximate time of 20 seconds to reach it.. When they reach the games area, the canoe would float back with an approximate time of 20 seconds to allow the other two players to use it. How to use it : The player could simply jump into it. However, when two people are in it and a third player tries to jump in, he can't. Each player in it could press "X" (or "Square") to activate it.
Size : Medium

-The Games Area : This area is filled with many broken carnival games. It is large and amazing for zombie trains. It contains the Stamin-up, the M16, and the Bowie Knife. Zombies spawn from 2 barriers found there. If the players reached this room from the "Tunnel of Love" side the zombies would reach them by running in the river as it isn't deep. It contains the power switch which would open the door to the Roller Coaster, and activate scattered teleporters like the ones in "Five" which would take you to a random opened room (each room has 1 of them). It has 1 turret on a wall.
Size : Large

-The Roller Coaster : The Roller Coaster could be ridden for 1500 points. All players must ride it at the same time. Each player jumps into 1 slot, and 1 player pays the points. When riding it, some weapons such as G11, sniper rifles, or frag grenades could help kill the zombies on the whole map because of easier aiming. The coaster goes around the whole map. Then, almost at the end, broken rails would be reached. The Coaster would stop and send them flying  into a small building through a big broken hole in it. This would let them end up at the Accessing Room. The coaster would slowly go back to the beginning of the rail.

-The Accessing Room : This is the room that was used to access the secret facility. It is very small and is filled with wires and electronics. It has a teleporter in it. There are three barriers. All the zombies that were around the map would teleport to the barriers and the hole from which the coaster entered, so it's advised to leave a few number of zombies behind. It has a switch. It could only be used between the rounds, or else the players will have to spend the next round in that room. It is crowded, and has no doors or ways to escape it, so a whole round in it is a certain death. This room has the Juggernog. When the switch is activated, the players have exactly three seconds to all jump into the teleporter, or else it's deactivated until the switch is used again (after another round). When the teleporter is used, the players are teleported into the first room of the secret 935 facility called The Research Room.
Size : Very Small

-The Research Room : This room contains Deadshot Daiquiri, Double Tap, and AK74u. It looks like a mine/cave but with computers in it. Zombies spawn from the ground and 2 barriers that get closed with rocks (like a barrier in CotD). It is extremely huge, but with obstacles for running such as computers and rocks. It contains a new kind of turret called "Lazer Turret" which is like a PaP'd turret. It costs 3000 to use and lasts twice as long as the normal turret (3 minutes). It is very effective in many situations. It has 1 door with 100 small light bulbs on it. There is no way to exit this room except via the door, but to be accessible the players must kill 100 zombies. Each zombie would make one light bulb on the door turn green. When 100 zombies are killed, the door directly opens (no pay needed). It would lead you to the Experimenting Room. This room also has semtexes.
Size : Huge (like the Bio-Dome)

-The Experimenting Room : This room has Mule Kick, AK47, Pack a Punch, and a teleporter. It also looks like a mine, but with cages and dead/zombified animals in them. The AK47 costs 2000 to buy. The Pack a Punch is in the middle of the room, so zombies CAN attack you while Pack a Punching. This room also has the "Lazer Turret". The teleporter can be activated using four switches in the room. Each switch costs 250 points. If playing solo, the player can buy all the switches and each costs 75 points. If playing coop with under 4 players, a player is allowed to buy two of the switches. If playing 4 player coop each player is allowed to buy one switch (to enforce teamwork in playing). The teleporter can't be used unless all 4 players jump into it. It takes you back to the mainframe in the Arcade Room.
Size : Huge (like the Bio-Dome)

Re-birth (will explain later)

New Weapon/Perk-a-Cola :
Rebirth :
Name : Re-birth
PaP name : Re-generator V. 1.2
Appearance : Similar to the VR-11 but with an overall black color with hi-tech glowing green lines, and an opening in front like that of the wunderwaffe. When shot a dark purple beam covers the head of the zombie like a cloud until the brain regenerates. When pack a punched, the color would stay black but with red hi-tech glowing lines all over, and the beam would be black when shot.
Description : The common fact about those zombies is that element 115 regenerated their bodies but their brains were still dead, so this weapon re-generates 1 of the zombies' brains (per shot) and that zombie would start attacking the others. The zombified appearence of the target would still be the same thus when attacking the other zombies they won't attack back... making that zombie very useful. The brain dies again after 30 seconds and the zombie would return back to normal, but after killing many other zombies.
Ammo :
-Regular : 2 with 12 spare
-PaP : 4 with 24 spare
Reload time : Similar to thundergun's reload, but instead the big disk like thing would be inserted at the bottom of the weapon through a circular opening that automatically pops out when ammo is finished. This means reloading takes some time like the thundergun. And NO reload cancel would be available with it.
Weight : Heavy, almost like an HK21
Accuracy : Extremely high, just like the Thundergun's and Wunderwaffe's accuracy.
ADS : the long metallic-like thin stick like the wunderwaffe (which means accuracy would be better without ADS).
PaP effect : 2 zombies' brains would be regenerated at once, and the effect would last 10 extra seconds.

C4 :
Name : C4
PaP name : C4.1
Appearance : Just like a normal C4, but when PaP'd it would have the same camo as other PaP'd weapon.
Description : It takes place of a weapon, not equipment. It has 10 times more damage than the claymore. When PaP'd the damage would become 20 times stronger than a claymore's.
Ammo :
-Regular : 10 C4's
-PaP : 20 C4.1's

AK47 :
You can mod an AK47 and PaP it. See info on COD wiki about it (same info would be on this map).

M60 :
Name : M60
PaP name : M-666
Appearance : Like the normal M60. When PaP'd it would have the PaP camo.
Description : When PaP'd it would shoot laser bullets 1.5 times stronger than the normal bullets and would have an increased fire rate.
Ammo :
-Regular : 100 + 500
-PaP : 150 + 750

Under-Cover :
Name : Under-Cover (by under-cover I don't mean like a spy or a ghost person, I mean it as cover for the lower side of the body)
Cost : 1000
Effect : Nova Crawlers and regular zombie crawlers cannot harm you what-so-ever (the gas from nova crawlers is not included, just the hits). Any crawlers caused by a player who bought this perk wouldn't die out, it would stay alive until a player kills it himself (very helpful for strategies that require crawlers or easter eggs... I always suffered from my crawlers dying alone).
Color : White like milk.
Taste : Just like sour milk (ruined/expired). Characters mention this in some quotes.
Icon : Knee Braces

Slashee :
Name : Slashee (as in Slushie but with a slash for knives)
Cost : 3500
Effects :
-Recover twice as fast from knives
-Knife kills give you only half the normal amount of points, but the kills are MUCH faster (mentioned down)
-Rounds 1-5 : Bowie Knife : 1 knife to kill - Ballistic Knife : 1 knife to kill (normal and PaP) - Normal Knife : 1 knife to kill
-Rounds 6-10 : Bowie Knife : 1 knife to kill - Ballistic Knife : 1 knife to kill (normal and PaP) - Normal Knife : 2 knives to kill
-Rounds 11-15 : Bowie Knife : 1 knife to kill - Ballistic Knife : 2 knives to kill (PaP needs only 1) - Normal Knife : 2 knives to kill
-Rounds 16-25 : Bowie Knife : 1 knife to kill - Ballistic Knife : 2 knives to kill (normal and PaP) - Normal Knife : 3 knives to kill
-Rounds 26-30 : Bowie Knife : 1 knife to kill - Ballistic Knife : 3 knives to kill (PaP needs 2 knives) - Normal Knife : 4 knives to kill
-Rounds 31+ : Bowie Knife : 2 knives to kill - Ballistic Knife : 3 knives to kill (normal and PaP) - Normal Knife : 4 knives to kill
Color : Brown
