Level 2: Times Square - part 1 Ghostbusters Guide
Last update: 11 May 2016
Level walkthrough: You start the game on the streets of New York. Ignore a large boss creature seen in the distance, because you won't have to worry about its actions for the time being. Instead focus on following Ecto 1. You'll soon be attacked by a first group of ghosts. Make sure to scan a spirit called Marshmallow Mini and then start using your Proton Gun. Thankfully, all of these creatures will die quickly.
Wait for Stay Puft to destroy nearby cars, unlocking a passageway. Get ready to take a scan of a new phantom - Hobo Ghost. I would now recommend that you follow instructions given to you by your colleagues. Use the super slammer on Ecto 1 to eliminate enemy ghosts quickly. The biggest advantage here is that you won't have to struggle with the captured ghost. All you have to do is to make it touch the roof of the car.
Keep pushing forward, eliminating hostile creatures along the way. Each time you attack a new group of ghosts focus on a single target. Make a stop once you've reached a large number of obstacles. You'll be rewarded with a short cut-scene here after which you'll have a chance to scan a new ghost - Stone Gargoyle.
Thankfully eliminating the gargoyles is going to be easy, because you won't have to trap them. Nevertheless you should acknowledge the fact that they're going to be more resistant to your Proton Gun than other ghosts, so they won't go down quickly. Aside from the gargoyles you'll also be dealing with Construction Worker Ghosts, so make sure to take a new scan.
Be careful while fighting the flying ghosts, because their attacks may result in your character losing a lot of health. Thankfully you'll be allowed to use Ecto 1 to trap them quickly and painlessly. Watch out for your teammates and revive them each time they're in need of healing. Wait for Ecto 1 to park in an alley when it's all over. Enter a nearby laundromat afterwards.
Ignore the moving washing machines, because they don't pose a threat. Go to the other side of the laundromat. Before you exit make sure to explore a small room to your right. This will allow you to get your hands on the first artifact - Gaillano's Enchanted Pail. You may head outside.
Once you've left the building turn right and use your newly acquired ability. You will be allowed to fire projectiles called Boson Darts. Make sure to maintain safe distance if you don't want to receive any injuries being result of an explosion. Destroy the obstacles in the alley and wait for Ecto 1 to show up. Follow the car to a new alleyway.
Explore the area behind a large truck parked to your right and you shouldn't have any major problems finding the second artifact - 3-Toed Jenkin's Midnight Goose. You may now proceed to your left. Use Boson Darts again to get rid of a wooden obstacle. Proceed forward, but turn left when you have the chance. Explore a new small alley to find the third artifact - Patrelli's Mischievous Cone.
Return to the area where Ecto 1 is parked and begin moving towards one of the main streets of New York. Once you get there take your time exploring your surroundings. You'll find a lot of black slime, but you won't have to scan it. Wait for a new type of a ghost to appear - Opera Diva Ghost.
Obviously you'll have to use your PKE meter to scan the creature. Afterwards you'll be allowed to engage the spirit in open combat. Watch out for diva's shock wave, because it can deal a lot of damage. You'll soon notice that other ghosts have arrived in the area. I would recommend focusing on the gargoyles first, especially since they'll be the easiest ones to neutralize.
Keep attacking enemy units and make sure to keep placing new traps and to attract the wraiths to them. Ignore Stay Puft for the time being, because your top priority at the moment is to eliminate all hostile ghosts. Once this is done you'll be rewarded with a new cut-scene.
