If you lose, the chapter simply ends.

Guide your way through the terrifying 'Butterfly' chapter of Heavy Rain. Learn how to navigate the glass pipe and survive the electric condensers to complete Ethan's trial.

Alright, so you're at Chapter 21, 'The Butterfly,' and things are about to get seriously intense for Ethan. This chapter is all about pushing him to his limits, and if you mess up too badly, well, it's game over for this particular trial. Don't worry, though, I'll walk you through it.

First off, you'll arrive at an abandoned power station. Get out of the car and head left until you find a gap in the fence. You'll need to hold Up, R1, and R2 together to squeeze through. Once inside, look for a door with a butterfly painted on it and head through. Inside, you'll find a crank handle. Tap Up on the D-pad, then mash [X] like crazy to force the door open. Grab the matches and get ready to crawl into a dark pipe – it's the only way forward.

As soon as you enter the pipe, the door slams shut behind you. Talk about trapped! Just keep pushing forward, but here's where it gets rough: the pipe is full of broken glass. You'll have to make Ethan crawl on his elbows and knees. Go slow! If you sprint for too long, the screen will start to fill with red, indicating Ethan's passing out. If this happens too much, he'll give up on the trial, and you'll have to restart. So, if you see the red tint, stop and rest until it fades.

At the first intersection, you'll need to pull out a match. The direction the flame points shows which way the wind is blowing, and that's your clue to the exit. Remember, the wind blows TOWARDS the exit, so turn in the direction the flame is pointing. You'll need to do this at each intersection to make sure you're heading the right way. If you're feeling brave or just impatient, the correct turns are: right, then left, then left again, and finally right.

Once you finally escape that nightmare pipe, you'll need to hold [Square], [X], and L1 to get Ethan back on his feet. Right in front of you is a shaft to slide down. Yeah, another tight squeeze, but there's no going back. Tap Down, then hold [Square], R1, and [X], and release to slide down. Get Ethan up by holding [O], L1, and [X]. You'll see an exit marked 'Coward,' but between you and it is a field of electrical condensers. This is another tough one.

There are a few ways to try and get through the condensers, but many are incredibly difficult, requiring complex button combinations and tight spaces. You can only get zapped three times; a fourth shock and Ethan flees, failing the trial. The best path I've found starts with the second condenser from the right. Hold [X], then R1, then [O] to slip through. For the second condenser, hold [O], L2, [X], R1, and L1. Now, this is tricky: DO NOT go forward to the third step. Instead, face left (change your camera angle if it helps) and hold [Triangle], [Square], R1, [X], and L1. Use your left hand for the shoulder buttons and spread your fingers for the face buttons. After that, change the camera back and go forward for the first step again. This time, you'll be crawling underneath: hold R1, L1, L2, and R2, then mash [X] while holding those buttons. Finally, for the last set of wires, hold R1 and [O], then release them to leap over and grab the next clue.

If you manage to get through the condenser field without getting zapped too many times, you'll earn the 'Electrified' Trophy. If you fail, you'll get the 'Coward!' Trophy. Either way, this chapter is a serious test of Ethan's resolve, and yours!
