"Walter Peck: I'm telling you, sir, the Ghostbusters are nothing but scam artists determined to throw a negative light on you and the City... and extort you for money!"

"Peter Venkman: Hello Peck. I own that suit in blue."

"Mayor Jock Mulligan: Both of you! Pipe down!"

"Egon Spengler: Mr. Mayor, an enormous event is on the horizon."

"Ray Stantz: Something at the Museum exhibit triggered a systemized psychic occurrence. Some mechanism we don't know the nature of yet."

"Walter Peck: No. Of course you don't."

"Egon Spengler: But it's feeding enormous energy somewhere."

"Ray Stantz: Something that's now in the process of breaking down the walls between our world...and another one."

"Egon Spengler: This other world is crossing through into ours. It started with simple ghosts and animated monsters."

"Ray Stantz: Now it's getting bigger. We don't know exactly what's next. But there's only room for one city here in this dimension."

"Egon Spengler: Two physical worlds can't exist in the same space. That's just elementary particle physics."

"Peter Venkman: We got the glimpse of the other world, Jock. It ain't pretty. It's like Brooklyn and the Bronx with no Queens in the middle."

"Egon Spengler: ...whole city blocks sinking into a fifth dimensional abyss!"

"Ray Stantz: Cockroaches the size of polo ponies."

"Egon Spengler: Panic in the streets!"

"Peter Venkman: How'd you like disco to come back? Bigger than ever."

"Mayor Jock Mulligan: I get it. We're in trouble. So what am I supposed to do?!"

"Ray Stantz: We need to prepare the city for the worst."

"Mayor Jock Mulligan: The city's my responsibility, not yours! Now go do your job and stop that thing!"

"Ray Stantz: This way, gentlemen."

"Egon Spengler: Well, this looks inviting."

"Winston Zeddemore: I'll be at the office watching over Ilyssa. Don't do anything fun without me."

"Ray Stantz: It probably goes without saying, but this is very strange."

"Peter Venkman: Well, that is your conversation starter. What's strange?"

"Egon Spengler: This tunnel network. What could it possibly have been built for?"

"Ray Stantz: I was thinking the same thing."

"Peter Venkman: Well, it could just be an old stream tunnel."

"Ray Stantz: No way, Peter. The design and values don't fit for moving stream, water, gas, electric, oil, trains, not even slime."

"Peter Venkman: What about Morlocks?"

"Ray Stantz: Morlocks would hate this kind of ornamentation."

"Egon Spengler: I don't recognize the alloy fabrication."

"Peter Venkman: So it's not steam, it's not Morlocks. But there's plenty of ghosts."

"Egon Spengler: You're right about that. There's more consistent, accelrated PKE blowing through here than I've ever seen. But is not the origin point. This is just a conduit."

"Ray Stantz: Look the the trail! The Chairman went that way! He's running down this tunnel!"

"Peter Venkman: Does it feel...weird in to you guys? Like, familiar-weird?"

"Ray Stantz: Well, we knew which way to go for a while at least. There's got to be another way around this."

"Peter Venkman: The trail leads to this sealed door, then stops."

"Ray Stantz: Man, I do not want this jerkball to get away again! The new cadet's alright."

"Peter Venkman: So far, not too shabby."

"Ray Stantz: Egon. I think this is a good a time as any to install a new CPS. The Meson Collider is extremely precise and deals a lot of damage, but takes a while to recharge. The Overload Pulse disperses a rapid burst of meson particles. You can fire each of them independently: they both work great. But you can also use them in tandem. Paint a target using the Meson Collider. After you've acquired the target, all expulsions from the Overload Pulse will home in on that target. Oh my. So MUCH black slime."

"Peter Venkman: Oh, it just seems like a lot because it's alive."

"Egon Spengler: The column! It's flowing upwards!"

"Ray Stantz: If you see a big yellow eye in there, poke it with something!"

"Egon Spengler: No yellow eye, Ray!"

"Ray Stantz: Maybe it already went up there."
