NightCry is a spiritual successor to the Clock Tower series and, true to its heritage, it is full of some classic adventure game BS—specifically, the variant that will reward you with a bad ending just because you missed an item 2 hours ago. Thankfully, NightCry is at least courteous enough to tell you how you screwed up, and even lets you load from a point where you can fix your mistake without having to start from the beginning of the game.

In each chapter there are conditions that the player must meet in order to go through certain routes. These requirements are listed below, divided into sections by which chapter and scene they are in. Following all of them will give you the best ending, but if you're looking for one of the bad ones be sure to check the "Endings" section to see which step you need to screw up on.

In the convenience store, take some quarters from one of the cash registers. You'll then need to go back to the room with the vending machines and buy a drink from the one you can inspect that isn't murdery. Instead of a refreshing beverage, you'll get a severed hand with a ring on its finger.

Once you charge John's phone, open SNS and post a message saying there's been a murder spree on the Oceanus.

In room 306 (which is in the hallway with the serving cart, south of the laundry room) the phone will start ringing. Answer it and talk to Jessica, who promises to meet Monica near the front desk. However, she's no where in sight once you get there... You'll find her in one of the lockers in the storage room. Incidentally, she'll be there whether you get her phone call or not, so don't worry if you've already used the elevator.

In the shack there is a pair of non-slip gloves near the sink. You'll need them later in the chapter, so be sure to pick them up before moving on.

There's also a radio that you can use to make a distress call. On the wall covered with posters there's a piece of paper with some radio channels written on it. Call channel 16 to contact the Coast Guard and they'll send help to the Oceanus.

Near the end of the chapter there is a well that you have to descend. Equip the gloves before going down.

However, before leaving the study be sure to read one of the books on top of the bookself. Not sure why this step is placed after the glove one, but whatever.

After that, inspect the artificial eye floating in the beaker on the desk. You'll then need to post on SNS to warn the students of a suspicious person with a fake eye.

After Jerome leaves, pick up the envelope that was pushed under the door. It's addressed to him, so be sure to give it to him later.

After talking to Jerome on the stairs, give him the envelope you found in scene 1.

Monica's necklace is in one of the shipping containers in the room with the lift. She's nearby, but she won't answer her phone. If you got John's number from Angie in scene 1, you can call his phone to pinpoint which container Monica is in. It won't open, so you will need to use a forklift to crash into it and break the lock.

After you've found Monica, talk to Eric and tell him she needs help. He’ll give you some antibiotics that both of you will need to take.

Talk to Monica and tell her about Professor Leonard's SNS post. She'll tell Rooney that it might be about Vigo.

In the sick bay you will find a grisly sight behind some curtains. Professor Leonard's mangled body is inside a tub, and the only thing keeping him alive is a life support machine. The poor man is begging for death, so turn it off to put him out of his misery.

Since Monica gave you John's wedding ring earlier, you should probably give it to Angie. She's hiding in the clothes store's changing stall. (If you forgot to get the ring from Monica you'll have to load from scene 3. You'll have to talk to her a few times before she gives it to you.)

In the captain's room, check the book on the computer desk. It's written in Russian, but it looks like someone was trying to translate its contents using a website.

In Vigo's room, check the drawers right next to the door. You'll find a photo that looks oddly familiar...

There's also a safe that was left unlocked. Inside is another fake eye and some money. The cash is useless, but the eye is probably the most important item in the game.

Requirements: Follow all of the steps listed above. Congrats on your A ranking!

Requirements: Don't read the diary or find the family photo.

Requirements: Don't take the antibiotics Eric gives you.

Requirements: Don't return the wedding ring to Angie. You also get this ending if you didn't give the envelope to Jerome.

Requirements: Don't use the Eye of the Kassites.

Requirements: Don't turn off the life support. You also get this ending if you didn't read the memoirs in chapter 2.

Requirements: Don't put on the gloves before going down the well. You also get this ending if you didn't find Jessica in chapter 1.

Requirements: Don't post to SNS with John's phone.
