Just let this thread die and comment when my v2 comes out

Short Description:
In Left 4 Dead: Rooftop Finale The object for the survivors is to kill all of the zombies that come after them, and last for 5 minutes without dying. For the Infected the object is to kill the survivors.

Map Description:
Rooftop Finale is a recreation of Left 4 Dead's No Mercy Rooftop Finale Crescendo event.

It has 4 buildings, The main building is where the survivors start, It has 8 Assault Rifles, 8 Battle Rifles, and 8 Shotguns, and a button to start the infection, but I'll get to that later. The main building has 2 "pipes" leading off of it onto Two other buildings.

(inside the main building v)

The left building has a Trip mine on it (where the Pipe bombs/Molotovs would be) an Two teleporters where the Infected would come out.

The Right base has the exact same objects while being a very different layout.

The last building, or, part of a building, is the broken helipad. It holds no Objects and is a pretty good spot for hit and run smokers.

But wait, is that it?
What about the blue thing in the sky in picture 1?
What about the zombie spawns?
do they just use those 4 measly teleporters?
No that blue thing was the zombie spawn.

Why put a spawn room in the sky?
Because teleporters are too easy to camp
And the zombies get to choose where they spawn like in Left 4 Dead!
So can't they just run in as fast as possible before the survivors are ready?
No, Remember that button in the main building?
It starts the infection by unblocking the receiver node!

How does something in the main building unblock that pallet?
Well, here's how...

(Hold right bumper to flip warthog?)

The Warthog is holding a Fusion coil...so what?
Well when you flip the Warthog it drops the fusion coil to the ground when it hits the ground it explodes
Wont it just hit the grid and not explode?
It will hit the grid but that's what makes it explode!
Wait so you built the map high off the grid?
Yes I did and If you care why I'll explain that in the Misc. section.

So you flip the Warthog

It drops the fusion coil, explodes
So how does that free the zombies?

well, the run time minimum is set to four (there are 5 fusion coils on the level) and when the warthog coil blows up, it spawns another fusion coil somewhere else (at the zombie spawn).

The fusion coil that spawned (farthest left, it just spawned in the air) falls into the gravity lift (which accelerates the fusion coil) blowing up the gravity lift, the falling fusion coils, and the still fusion coils blow up the pallet (the warthog fusion coil, the gravity lift, and the still coils are set to never respawn and cause no trouble after the explosion)

(there is a tiny tiny crack that allows the coils to hit the pallet but it can't hit the infected)

See, no damage!

I take no credit for this switch it was made by some one else...I don't know who exactly but if you know tell me so I can edit my post giving them thanks.

(I have a needler spawn in the front left corner of the zombie spawn a radar jammer in the front right and a 7-wood/overshield spawn in the center I do not currently have a picture and I will get one as soon as possible)

This is where the zombies wait for 30 seconds before the outbreak

Long Description:

This is a very chaotic game with the zombies having only 3 second respawn and always starting with a sword. There are no pain pills or med kits and no attempt at them either, but I tried, I wanted pain pills and med kits as much as the next guy but It just can't happen. The fusion coil letting the zombies free automatically happens at 30 seconds so move fast preparing! And one Survivor has enough time to grab both trip mines and two weapons before the zombies automatically spawn. I also tried molotovs and pipe bombs but they didn't work either because the zombies could kill a survivor take his grenade and take out half of the survivor's health with one fire bomb, not fun. I also did my best to fix one fatal flaw, the survivors can jump off take the suicide minus and come back with full health, I did my best to fix this by having the spawn point as far away from the main building. There is only one way the survivors can face from the respawn so the infected can spawn kill (assassination) if they know someone jumped. The survivors respawn after 13 seconds (3 second spawn normally and 10 seconds for suicide).

Spawn times
Needler - 30 seconds doesn't spawn at start
Radar Jammer - 60 seconds doesn't spawn at start
7-Wood/Custom power-up - 150 seconds doesn't spawn at start
Trip mines on both sides - never respawn, spawn at start
Assault Rifle - Infinite respawn 8 on map (all in the same spot)
Battle Rifle - Infinite respawn 8 on map (all in the same spot)
Shotgun -Infinite respawn 8 on map (all in the same spot)

Initial Zombie count 50%

zombie kill points 1
killing a survivor 5
last man bonus 2
suicides -10

Zombie damage resistance 100%
Zombie Shield multiplier Normal
Zombie Damage modifier 75%
Zombie gravity 100%
Zombie movement speed 150%

Survivor damage resistance 500%
Survivor Shield multiplier 3x
Survivor Damage modifier 100%
Survivor gravity 150%
Survivor movement speed 100%

Miscellaneous:

-The Turrets function was changed from looking down the long alleyway to getting the infected that immediately jump from the shield doors.

-Remember that the smoker and tank can both push the survivors off the edge.

-The sword melee does more damage than the lunge swipe for swipe

-Shotgun should be your primary weapon and the AR and BR should be secondary weapons.

-Remember that you can destroy the radar jammer

-Needler is not infinite ammo so use it sparingly

-I originally had the first half of the level (Not just the finale) where you started with SMGs Maulers and pistols, the level worked out great until people got to the elevator shaft. No one ever made it past the elevator section simply because you came out of a hole where the infected could easily assassinate everyone who tried to pass. I tried everything to make it work but It just wouldn't work how I imagined it. After that disappointment I stopped working on L4D for a long time and decided to pick it up again recently and made what we have today!

-I made this before knowing about the other L4D levels

Enjoy!
