Public Library (part 1)

That's quite a crowd; too bad you've got work to do. Approach the lion statue, causing two ghosts to fly out and into the library. Follow them inside and up the stairs. After some antics go down, your teammates will inform you of a new weapon you can now test: the Dark Matter generator. It has two firing modes:

• Stasis Stream: Firing this at a ghost will slow it down, making it easier to target and then trap! However, make sure it doesn't overheat!
• Shock Blast: This is the shotgun of Ghostbusters. It packs a wallup, but only at close-range.

Now that you know how to use the new weapon, head downstairs and approach the display case by the right staircase to expose the ghost. Chase after him down the hall and into the large room on the right.

After stepping a short ways into the room, a Book Golem will appear. Although the other Ghostbusters suggest to "slow" him down, ignore their advice and instead use the Shock Blast repeatedly while circling around him from a few feet away. Because his attacks are slow, they should all miss so long as you continually circle around him. Once you've just about depleted his health, back away before delivering the final blast, as he'll explode exposing his energy ball--grap it with your Capture Beam and slam it loose, taking down the Golem once and for all.

With the Golem defeated, you'll find two doors ahead. Head through the left first to find the Portrait of Eleanor Twitty artifact, then approach the door on the right, which Ray will open for you. Follow him down the staircase and approach the bookshelf that Egon draws your attention to, causing the librarian ghost to appear. Follow her into the next room, then through another door on the left.

Alright, so you're going to have to work your way through a maze of moving bookshelves--they may slam you around a bit, but not enough to kill you. If you ever have trouble finding the route, just follow one of the walls--a path will eventually be revealed. Eventually, you'll wind through a small room where you'll encounter a bi-pedal enemy--shock blast him for a quick victory. Continue into the hall and make a left toward the next room.

As you explore the room, a stream of book-bats will storm in. Step to the side and Shock Blast 'em. Soon after, two ghosts will roll in, we also suggest Shock Blasting them at close-range, then going in for the capture. This portion can be difficult, so make sure to stay near your fellow ghost buster so you can keep him alive, allowing him to do the same.

With the room clear, proceed through the door in the corner toward the next room. There you'll face several more of those bi-pedal ghosts--shock blast 'em all then continue through the doorway. Proceed to the small area at the end of the room and use the PKE meter to scan the glowing spot, revealing the Librarian. Follow her back to the previous room and Shock Blast the book-bats that appear when you try to exit through the open door. Stay on the move to avoid being hit. Once clear, follow Ray through the door he opens.
