undertale

An new indie game that was just like any other game, has a story, has characters, and was not intended to really be anything more than just a game. Until the community around said game turned into pure cancer, and i do not use this word lightly. And if you are one of the few people who actually dislike the game and its community you might as well be a Jewish citizen in Nazi Germany, if they find out, they will give you hell. And they will not stop

I have not gone more than a day without hearing mention of undertale.

Undertale

An indie RPG created by Toby Fox that has sold extremely well and seems to have taken over the Internet.
The game follows the story of a human child who has fallen into The Underground, a society filled with monsters after humans sealed them away in a war long ago.

In battles, enemies attack your soul (which looks like a heart) in a bullet hell-like method, and you can either fight them, or via the ACT and MERCY buttons, figure out how to spare them.
The game's story is affected by how many monsters you kill, as well as which 'Boss Monsters' you kill.
It can be hard not to stumble across spoilers of this game when you are looking into it, as many popular characters are considered 'Walking Spoilers'.

Hey have you played Undertale yet?

Underoath

A Christian band that is from Florida. Even if it may be emo, though emo can be classified a million different ways, it's still heavy. Really, EMO is what the singer sings about rather than what his voice produces and guitars, etc.

Their newer music is shit.

Underoath is badass!

Undertale Community

the one community that makes you want to drink nail polish. it takes a psychotic flower, and turns it into porn that makes no sense. it involves goats having sex with skeletons, skeletons having sex with robots, incest, necrophilia, and tentacle porn if you accidentally stumble on porn of it.

in the afterlife...
dead guy 1: so how did you die?
dead guy 2: hit by a train, you?
dead guy 1: i committed suicide by drinking nail polish remover mixed with bleach.

dead guy 2: why?
dead guy 1:because i saw undertale porn in a supposedly child friendly undertale community.
dead guy 2: oh god, i had it easy. and i was in a hospital for 6 months in complete agony.

A shitty undertale game made by someone in the undertale fandom other than Toby Fox that’s barely finished.
