History NightmareFuel / Terraria

* Any time an early boss fight occurs, the scream will haunt new players.

* In Hardmode, smashing a demon altar can cause a single block anywhere in the world to become corrupted/crimsoned or hallowed. There is NO indication of this when you smash the altar, so anyone who read this and didn't know beforehand just had a MyGodWhatHaveIDone moment.

* One couldn't be blamed for using a third-party map viewer to take a good look at the world, its secrets, and layout. It's an incredibly useful tool to find things such as ores, treasure chests, and secret rooms. It also leads to ParanoiaFuel upon defeating the Wall of Flesh, unleashing the rays of evil and Hallow, and destroying the evil altars, finding more and more infected blocks in the middle of nowhere. All the while the existing evil/Hallow grows...and grows...and grows...and there's little you can do to stop it.

* The 'Remix' secret world seed added in 1.4.4 initially begins as a neat little reverse-romp through the game's normal progression--as in, you start in the Underworld and have to dig upward to progress through the game. Strangely enough, the seed needed to access the Remix world is 'don't dig up', which is a bit counter-intuitive advice considering the player HAS to do just that to get anything done. Upon finally reaching the surface, it becomes clear what the seed itself was warning about--''the entire surface of Remix worlds are entirely covered in Corruption or Crimson.'' Not just that, but the world is stuck in an eternal night with no sun or moon, enemy spawns are heightened on the surface, the Dungeon and Jungle Temple (which is now located on the surface for whatever reason) are both painted either purple or red depending on the world evil, and all living trees are generated without any leaves, making them appear dead. Suddenly, it becomes abundantly clear that your character starts underground for a reason...

** The Eater of Worlds. Full stop. The thing looks scary with its rotten flesh and overabundance of eyeballs, and if you cut it in half, YOU END UP FIGHTING TWO. If you're a new player who doesn't know what smashing Shadow Orbs does? "Hmmm, another Shadow Orb. What's this one drop? Wait - The Eater of Worlds has Awoken? What's that me-" [[OhCrap GIANT WORM OUT OF NOWHERE]]. There's a good reason that ''thing'' provides the current page image.

** The Hardmode enemies are no slouch either; Basilisks, [[ScaryScorpions Sand Poachers,]] [[OurGhoulsAreCreepier Ghouls,]] [[SnakePeople Lamias]] and [[UpToEleven Dune Splicers, which are an even bigger and uglier version of Tomb Crawlers.]]

Terraria looks like a very fun and colorful game, just like ''VideoGame/{{Minecraft}}''. However, there are [[NauseaFuel more than]] [[EldritchAbomination a few]] [[CrapsackWorld reasons]] that [[NightmareFuel this isn't very true.]]

** The console and mobile version's hardest boss, Ocram, who is debatably worthy of final boss status, is hands down the boss most worthy of being called an EldritchAbomination, at least aside from the Moon Lord himself.

*** Its fight is designed to be panic-inducing. Being the only AdvancingBossOfDoom, your only option is to run from it while attempting to fight back. Trying to escape will only earn you either a forceful dragging back if you're lucky, and instant death if you're not. And if it chases you to the end of the map and it isn't dead yet?

* Every so often, the moon turns blood-red, and it drives ''everything'' in Terraria into varying degrees of a maddened frenzy. Zombies start mutating into shambling person-shaped blood clots, Demon Eyes start coalescing into Dripplers that can more accurately track a target, several major critters turn into violent KillerRabbits (figuratively ''and'' literally), several aquatic monstrosities begin to climb up to the surface depths and take any fishermen by surprise. Perhaps most worrying is that this even affects the NPCs, all of them going into strangely foul moods.

* You can buy a [[VideoGame/Portal1 Companion Cube pet]], the rarest item sold by the Travelling Merchant for a whopping ''5 platinum coins.'' It might seem like a silly ShoutOut at first, but if you let it fall in lava, it will make the death sound of the Lunatic Cultist. If the cube is submerged long enough, it has a chance of making the [[HellIsThatNoise death sound of the]] ''[[HellIsThatNoise Moon Lord]]''. It has been noted for catching some players, new or not, off guard due to this.

* Spider Nests are this for those with arachnophobia. The worst part? An NPC is held captive there.
