Mass Panic Outside on the street, use the Ecto-1B's super slammer to capture the contruction worker and hobo ghosts. You do not need to deploy any traps of your own, but look into improving them with the money you're earning.
| Ghosts and Gargoyles |
The gargoyles are deadly if you don't get rid of them. Use the capture beam and slam them down towards the ground or against buildings. Never throw the gargoyles skyward -- or they will come back and rip your face off.
| Spin Cycle |
Enter the laundromat and Spengler will unlock the Boson Dart. If you have the $26,000 buy the supercharger and immunity upgrades immediately (immunity before supercharger, since you can cool off the pack manually). Only one dart can appear at a time, so using the supercharger is pointless until you need that extra damage. Follow the car to the opera house.
| Hindenburg the Musical |
You can scan the black slime portals where the opera ghosts are coming out from. Smash the gargoyles and trap the rest of the ghosts.
| Shadow of Stay Puft |
Lure the Stay Puft by shooting boson darts at its body when Stanz gives you the go ahead. Otherwise, just fight off the marshmallow minis and get to the office building.
| Marshmallow Minis |
During the attack of the mini-marshmallows in the lobby, grab the red phone (artifact) otherwise you have to do this section again. Boson darts make things easy. Detonate one in the middle of a monster crowd and watch the sugar fly.
| Race to the Roof |
You should be at the architectural office now. Destroy everything in the studio for the extra trophy or achievement. You can also use the PKE meter to find the monsters and proceed to battle them.
| Puffy White Menace |
This checkpoint occurs at the hallway past the office, when Stay Puft tries to lunge for Alyssa Milano. Shoot the hand with the boson dart to drive off Stay Puft.
| Damsel Distressed |
An easy section. Just run up the stairs to the roof. It makes perfect sense when a giant rampaging monster is trying to destroy the building you're in. Head to the roof.
| Ghosts at Work |
The battle on the roof is against construction worker ghosts. With so many Ghostbusters, they should not pose any problems. Trap them all and scan them (if you haven't) for the entries. When Stay Puft appears, use a boson dart to knock him off the building.
| Rise and Fall of Stay Puft |
Fight the Stay Puft Marshmallow Man by roasting the mini-monsters he spawns from his fingers. Keep the pack from overheating so you can blast stream the stuff he barfs from his mouth (it will knock you off and kill you). Once the giant is really close, Stanz will remark a boson dart will knock him back down. Do this a few more times and eventually, the fat guy will go splat.
One of the first two ghost types to attack in Times Square. You will fight a few more on the roof before fighting the Stay Puft, but scannign them on the street means more money earlier.
This is the other ghost type in Times Square's streets. A few more attack with the Opera Divas after the alley.
The gargoyles appear with the cut-scene. Good luck fighting them on hard.
The mini-monsters the Stay Puft farts out. A ton will be available for scanning in the office building, but you can scan them earlier in the streets.
At the Hindenburg opera. Be sure to scan the black slime portals these ghosts come out from so you get that out of the way.
These portals spawn enemies. You cannot get rid of them until later, so scan them now. The other Ghostbusters will use their slime throwers to erase these enemies later in the game.
The Stay Puft. Scan him either on the street, or when he is trying to grab Alyssa Milano in the building. Trying to scan him while hanging over the roof is a bad idea, but it can be done.
