Minecraft Green Run

I have been thinking about a Green Run project for a long time now but I simply cannot do it alone so I am enlisting and avid builders, redstone engineers and texture pack creators to help me with this idea. I have already thought up most of the plans and blueprints but I need a lot of help to implement them. So heres what I have so far....

Map.
The map will be a replica of the Green Run in minecraft.

Bus.
I have not figured out entirely how to make the bus but perhaps some form of teleport command?

Zombies.
There will be 5 types of zombies identical to the ones in-game.

Runners.
These appear at the start of each round and have a large number of potion effects giving them there power. When they spawn a large amount of ghasts will spawn in a one block space, dying and therefore creating a screeching noise similiar to that made by the in-game zombies

Walkers

These are the old run of the mill zombies and are nothing special. They have a few perks to make them stronger.

Creepy FaceHugger Baby Things.

These will be baby zombies with a load of perks such as speed and jump height increased.

Crawlers.
These will be spiders with slowness and a few other perks.

Exploder Things.
These will be creepers, they will not actually harm the landscape only the players.
Textures.
I will need someone to make a custom 32x32 texture pack for the map.

Points.
The point system will be similiar to the one in actual Green Run and will have the points on the side of the screen.

Guns.
The guns will be done by using various enchantments to create different weapons. They will be paintings on the wall and when a button below the painting is clicked the players buy the said gun with the points they have earned.

Perks.
The perks in-game can only be unlocked once the power is turned on and they will dispense various items depending on what machine it is e.g. Juggernog = a potion of strength with a few other enchantments.

Doors.
Doors can be opened by players spending points, by activating the power or by maing a power source.

Items.
Like in the real Call Of Duty Green Run players will be able to make certain items to help them with fending off the hordes. I have not quite figured this out yet but perhaps the player finds the items, places them in a hopper and another item pops into a nearby chest.

Mystery Box.
The mystery box will be a redstone chest that dispenses a random weapon via hoppers, it will also have beacons etc. to add effects.

Players
Players will start with a pistol(bow) and a knife(sword). They will respawn in the last town they entered. The game will host 4 players.

Thank you for checking out my idea!
