7 Bad Endings You Can Easily Get by Accident

The number of times I stumbled into the bad ending, thought "wow, downer ending, ok" and then years later found out that there were multiple endings

Arguably the Dark Souls ending you got was the good one.
It's theoretically the end of Gwyn's Age of Fire, being rid of the manipulative gods and beginning an Age of Men. You're king now, the serpents are there to welcome you, it's not their fault they're gross and weird.
It's also not humanity's fault the power of men is dark, and results in the abyss and terrifying monsters like Manus...
But at least you weren't used as fuel.

...Even more arguably, there is no good ending.

Blasphemous automatically locks you into the bad ending unless you perform an obscure mechanic involving dying several times while equipping an otherwise useless trinket and exploring the map to complete several arena encounters.

"Did the Empire kill ANY Jedi that day?" Yeah, Aayla Secura, sadly. And Shaak Ti, four different ways.

So, hilarious thing about that "switch characters" prompt for Revelations 2? I was playing the game co-op with my husband. He was playing Claire. I was playing Moira. When this prompt appears in co-op, BOTH characters get to button-mash for it. And my husband is the superior gamer when it comes to button-mashing, so of course, he got the gun and we got screwed out of the good ending. We had to google what we did wrong and how to get the good ending because we were super confused.

Majora's Mask: simply forgetting to use the Song of Time and watching as then Nightmare Moon destroys everything.

Man that Oddworld ending wasn’t kidding around, jeez.

Punctuation is important! When someone is talking about how you’re gonna die, “I know exactly what we’re gonna do” sounds a whole lot more hopeful than “I know. Exactly what we’re gonna do.”

I love how insistent Luke is that the Cyberpunk ending wasn't completely telegraphed and he absolutely did not deserve that richly deserved cyber bollicking.

In the original Dishonored, I got caught sneaking on the first level because I didn't know how to play the game yet. I killed so many people trying to escape that I had permanently bad reputation, and even though I played the rest of the game silently and non-lethally, I still got the bad ending. Oof.

Yoda: "When gone am I, the last of the jedi you will be ...along with your father's former apprentice Ahsoka. And some guy called Ezra. And Baby Me. And Gungi..."

Poor Luke. He’s going to get inundated with comments about how, “the Dark Lord ending is the good ending ACTUALLY”

That resident evil ending was so annoying for me. I didnt know what i did wrong. Had to look it up online afterwards and then noticed the other button i was supposed to press.

Corpse Party: Not only does it have bad endings, but also wrong endings that are essentially just game over screens in which you have to sit through a thoroughly described + voice acted scenario of just how horribly your character is being killed. And all of them can be acquired terribly easily.

I love how Grunty is too big for her own creation so she has to squash her head down to get inside.

I'd put forwards Hollow Knight as an easy bad ending. Given it's a metroidvania-style game, you wouldn't think (on a first playthrough) that you could be missing anything critical to the end of the game if you can already get there, but if you fail to assemble the Void Heart, you only succeed in extending the time the infection is contained, leaving your player character doomed to become the next failed vessel.

Bonus points to the fact you can get a nearly identical ending if you fail to recognise how to get from the first "phase" into the next even if you DO have the Void Heart.

The Cyberpunk bad ending was pretty easy to assume with how V insinuates what they want to do. That said yeah, probably should've been a bit more black and white with it. Thankfully it doesn't force you into some "final quest" that you have to do before you realize your accidental choice. Just a cutscene and then you can reload.

Bit of an odd choice to choose Soulstorm over the original Oddworld.
You get the bad ending for not saving enough people, and you can only save one at a time

Abe gets dropped into a shredder while begging for his life!
(But if you kill everyone then you get a grenade launcher)

One that you missed, in my opinion, is Castlevania Dawn of Sorrow. About 2/3rds of the way through the game, in order to not get the bad ending, you have to put on a normally useless accessory before walking into a cutscene. There is no warning, and no hints.

Donkey Kong 64 also gave you a GAME OVER every time you quit and that drove me nuts! Collecting all those bannannas was no small task and I had to share the console with two brothers. I always turned the N64 off as quickly as possible so I didn't have to see the island destoyed.
