Limbo is a 2-D puzzle platforming horror game by Playdead, an independent game studio based in Copenhagen, Denmark. This is their first game. It was originally released on Xbox LIVE Arcade, and was later ported with additional content to the PlayStation Network and Steam.The game's story is simple. You control a nameless young boy in Limbo, searching for his sister. There is no dialog or text of any kind to guide you. Just the boy and an incredibly dark, oppressive, crapsack environment. There are many deadly puzzles, challenges and traps that can get you killed. In many shockingly violent ways. A Gore Filter can make the deaths less grisly, but no less terrifying. When combined with the protagonist's limited moveset — he's entirely unarmed and can only jump, push/pull objects (like boxes and levers), climb ledges, and swing on ropes — Limbo's sense of helplessness and trepidation is intense. Something of a huge contrast and surprise between regional ratings, the ESRB somehow let the game pass with only a T for Teen rating, while PEGI gave it an 18, the strictest rating they have. If you see the more graphic deaths, you'll understand why you'd think the ESRB would have, or even should have given it an M for mature rating instead.Players draw many comparisons to Braid, another Xbox Live puzzle platformer that cost 1200 points at release, lasts about four to five hours on a first playthrough, has a unique art style, and says some interesting things about videogame storytelling.Do not confuse with Limbo of the Lost, although that's pretty terrifying in its own special way. For the opposite of Limbo, there is Lucidity.
This game provides examples of:
100% Completion: If you finish the main game path without exploring too much you'll only receive a 75% or so complete rating. Finding the bonuses fills in the rest of the percentage.
All Just a Dream: During the final puzzle, the boy crashes into a magical wall and lies down unconscious in a forest. When you get up and can move again, you can move left, only to find more forest where the hazardous industrial world once was. To your right, his sister awaits, playing in the grass, as if your whole adventure was just a dream... Or Was It a Dream?
All Webbed Up: Happens to the protagonist in the early parts of the game. However, he can struggle free and move around with enough effort.
Ambiguous Ending: You find your sister sitting peacefully in a clearing, apparently picking flowers. She sees you and stands up. Fade to black.
Badass Adorable: You, being a young child that can climb ladders, jump from rope to rope, and deal with gigantic bugs even when you can't fight them directly.
Bear Trap: A couple of them early on. The first one you see are actually two next to each other; unless you spot the signs, you'll die horribly. After that, there's two more which are both used to your own advantage.
Body Horror: There are glowing worms (popularly referred to as 'brain slugs') that burrow into your head and force you to walk in one direction. Before that happens to you, you encounter other kids who are in the same situation; some are dead.
Bonus Stage: The PSN and PC versions have one if you collect all the insect eggs. Its entrance is past where the "Alone in the Dark" egg is found, and when you beat it you come out at the elevator underneath which you find the "Under Ground" egg. It's extremely long, dark, and difficult, and there are several places where you'll have to navigate by sound alone.
Bullet Time: Just as you solve the last puzzle. You get an excellent view of the protagonist flying slowly through an energy barrier and tumbling pitifully up a grassy hill. Then you get up and finally find your sister.
Controllable Helplessness: Early on, you run across some goop on the floor that slows you to a crawl, then finally immobilizes you. You twig that it's spider webbing just as the giant spider approaches and websyou up. In the demo, the spider just kills you at this point instead.
Crate Expectations: Puzzle elements, to the point where you'll know a puzzle is coming up whenever you see a crate or box.
Creepy Child: The other kids you meet early on, some of whom try to kill you.
Dark Is Not Evil: There are some very sinister-looking black worms that hang from the ceiling and have vicious mandibles. They're no threat to you, but they do a good job eating those brain slugs. There's also some sort of dog-gerbil thing at one point, but all it does is run away when you go near it. You can even earn it as a pet for your Xbox avatar after beating the game.
This player could have sworn those were birds and a frog...
Dark World: Dark, dank, colorless, and very very scary.
Deliberately Monochrome: The only time you see some color is when Friend Notifications or Achievement/Trophy alerts pop up, and that's only on the console versions. On Steam, even the Achievement pop-up is black and white except if you're using a custom Steam skin that has color.
Determinator: The boy. Also, the giant spider. It really wants to eat you.
Downer Ending: The boy finds his sister. Roll credits. The title screen fades in to the same area, but the player might just see resemblances between the final image and the title screen. See Noodle Incident.
Down the Drain: At least one of the sections of the game where you have to outrun water.
Eldritch Location: The entirety of Limbo with all its darkness, peril, cruelty of the residents, and the strange gravity levels near the end. You end up inside of it by mysteriously waking up in its forest. You leave it by somehow passing through a magical wall at the last gravity level.
Gorn: Touch a bear trap? You get snapped in half. Get hit with a buzzsaw? You get chopped to pieces. Get hit lightly? You get sawed in half with visible entrails. Get squashed? Sticky chunks stretch apart afterward. You can turn on a gore filter in the options that makes the screen cut to black the moment you die, but it doesn't remove the sounds.
Gravity Screw: Final section of the game. First only items, then you too. A few sections earlier there is a rotational variation of it though.
Hailfire Peaks: The very last part of the game is a mash-up of many previous areas; forest, industrial, part of the hotel sign, and so on.
Heartbeat Soundtrack: Not a human heartbeat, but the Giant Spider has a distinctive, low-pitched buzzing noise that plays in the background whenever it's around. It finally stops when you shove the thing into a spike pit.
Hell Hotel: More accurately, limbo hotel. A section of the game takes place there.
Hope Spot: A few. Most notably the fake ending and the one in the secret level, where after a long and difficult trek dodging sawblades and other industrial dangers in complete darkness you come into a serene, quiet, and well-lit area. Then you're plunged back into the darkness and the machine guns open fire.
Interface Screw: When a brain slug drops on you, you are forced to run in the opposite direction from where you were heading and you can't stop. If you run into a patch of sunlight, you switch direction.
Noodle Incident: The kid and his sister are dead. We find that out in the ending and title screen. But how did they both die and why is the rope ladder on their treehouse broken? Maybe it's best we don't know.
Nothing Is Scarier: A lot of things in the game are scary specifically because you can't see them clearly — strange bundles lying in the grass or hanging from ropes that might be dead bodies, unearthly creatures that run away or attack you before you can get a good look at them, deserted industrial landscapes and creaking machinery whose function remains a mystery, and so on.
Pressure Plate: Some of the buttons. A rather nasty trap early on has one apparent pressure plate actually being the safe zone for a huge smasher; hopping onto the depressions to its sides is what kills you. This would be less annoying if it wasn't right next to another identical trap where the thing sticking up is the kill-button.
Puppeteer Parasite: Glowing slugs may plop onto your head. They force you to walk or run forward—you can only control your speed, and whether or not you jump. They are sensitive to bright lights, however, and if you run into one, it will sizzle and force you to run in the opposite direction. There are some ceiling-dwelling critters that can reach out and pluck the brain slug from your head, but getting to them is the real challenge. When we first see the slugs in action, it's on another human who's being forced into a pool of water, to drown....
Rasputinian Death: The aforementioned spider. First you chop three of its legs off with a bear trap, then you lure it into the path of an oncoming boulder, which in turn knocks it over a cliff, then you pull out its last leg, and finally you roll its body into a spike pit.
Ravens and Crows: At one point you find a lone crow cawing while perched on top of a hanging cage. The hanging cage next to the one with the crow has a human corpse inside of it.
Scarecrow Solution: Not long into the forest level, you see some more of those dreaded spider legs poking out from a nearby tree—but they're a fake. The hostile humans in the area set them up to scare you away.
Spikes of Doom: In some sections. And you're not the only one vulnerable to them.
Stupidity Is the Only Option: The parasitic worms are easy to see. Doesn't matter; you still have to pass under them and get infected. There's no avoiding them.
Super Drowning Skills: In any body of water that comes up above your head, you drown almost immediately and sink like a stone. There's an audible cue for near-drowning; the soundtrack will begin to fade and it's only after that point that you'll die. You can still press the movement keys which causes the boy to twitch as he dies...
Trial-and-Error Gameplay: In fact, the developer described it as "trial-and-death" gameplay. Chances are, on your first playthrough, that you'll die quite often while trying to figure out a couple puzzles. The best example of this is the pair of mechanical crushers early on. To avoid causing the first one to fall on you, you must step on the elevated square underneath it. For the second one, you have to avoid an identical square. There's no indication of the solution, other than dying and trying again. It is so easy to die in this game that one of the Xbox achievements for the game is a "no-death run" in which you're allowed to die up to five times and still get the achievement.
Videogame Caring Potential: The protagonist is a child. A cute kid who is getting slaughtered by everything. Give it a few deaths and you'll be dodging the puzzles for his sake, not your own.
Videogame Cruelty Potential: After beating the game the player has the option of replaying any of the chapters. Kind gamers can enjoy their favorite puzzles over and over while helping the boy reach his goal. Sadistic players can see just how many different ways its possible to kill the poor kid...
Who Forgot the Lights?: Some parts of the game are not recommended to be played during daytime. It's that dark.
When It Rains, It Pours: When you turn on a weather machine, it starts raining so hard that the next portion of gameplay is devoted to avoiding drowning in the ever-rising water.
Your Princess Is in Another Castle: A fair bit of the way into the industrial portion of the game, you will emerge in a small forested area, with the treehouse and the girl you were looking for—then a Brain Slug plops onto your head and forces you to run the other way. When you get back, there is no forest or treehouse...
