If you're thinking of replaying the game, these hints will share the decisions you need to make to get each ending.

Some choices don't matter at all - like the one with Vincent's father at the start of the game, and the yes / no choice with The Bull near the end - but to be on the safe side, follow the ones listed below exactly.

Ending A mostly relies on you consistently being a good, selfless friend.

When getting Nick to open the treehouse window - "Don't worry man, if I break a leg I will silently crawl back to my home." When talking to Tony about the pony show - "If you say so... I guess I'll give it a second chance." When confronted by wolves - "Let's scare them by acting aggressive, I charge them you cover me!" After New Frontier locks down - "You are not Rocko, we are not part of the Special Forces. We can't even legally buy beer." After repairing the coffee machine - "Yeah, you are a smart guy, we get it. Can you calculate the odds of leaving this place in one piece?" When the elevator opens - "Take the elevator, I'll try to hold them off." When you're dealing with the Hellmite - "Believe me, I don't like the idea either, but you have to play with the cards you are dealt." When you validate a train departure - "You should try to just... say the first thing that comes to mind. That could help." When you complete the train battle - "Team Mystery Stalkers!"

When you reach the communications tower, follow these hints.

Ending B mostly relies on you being a bad friend, with some selfless moments.

When getting Nick to open the treehouse window - "What's wrong, Nick? Chicken?" When talking to Tony about the pony show - "Don't go around saying that. Ponies are lame." When confronted by wolves - "Run! Every man for himself! Let the quicker mourn the slower." After New Frontier locks down - "Probably, he would stop complaining, and start acting like a real man." After repairing the coffee machine - "Stop acting as if you know everything, I bet you don't even know who Tamara Gomez is." When the elevator opens - "Take the elevator, I'll try to hold them off." When you validate a train departure - "You should try to just... say the first thing that comes to mind. That could help." When you're dealing with the Hellmite - "Don't be a wuss, think about this as if it were a giant cockroach." When you complete the train battle - "Team Mystery Stalkers!"

When you reach the underground train station, follow these hints.

Ending C also mostly relies on you being a bad friend, with some rare exceptions.

When getting Nick to open the treehouse window - "What's wrong, Nick? Chicken?" When talking to Tony about the pony show - "Don't go around saying that. Ponies are lame." When confronted by wolves - "Run! Every man for himself! Let the quicker mourn the slower." After New Frontier locks down - "Probably, he would stop complaining, and start acting like a real man." After repairing the coffee machine - "Stop acting as if you know everything, I bet you don't even know who Tamara Gomez is." When the elevator opens - "Let's scatter, that way there's better chance of one of us escaping." When you validate a train departure - "I don't act stupid when I talk to Samantha Silverman. You look stupid when you freeze." When you're dealing with the Hellmite - "Don't be a wuss, think about this as if it were a giant cockroach." When you complete the train battle - "Well... technically I did it"

When you reach the underground laundry room, follow these hints.
