Compare Antichamber prices across trusted key stores and find the best deal. Developed by Alexander Bruce. Published by Demruth. Released on 1/31/2013. Available on PC, Mac, Linux. Genres: Adventure, Indie. Metacritic score: 82/100.

A solo-crafted puzzle box that dismantles everything your muscle memory knows about space, direction, and logic, then dares you to rebuild it from scratch.

My first hour with Antichamber felt like being handed a map written in a language I almost recognised. Corridors loop back on themselves. Staircases deposit you nowhere near where geometry promised. Turning around in a hallway reveals a completely different hallway behind you. Alexander Bruce, working alone for years, built this entire world on non-Euclidean geometry, the kind that bends normal spatial rules until they snap, and the result is one of the most singular first-person puzzle games ever released on PC. The structure is non-linear in a way that feels genuinely free rather than merely open. A central hub room fills its walls with a map and small illustrated proverbs as you complete puzzles, letting you teleport back to any area at will. That teleport system is doing more work than it appears: it functions as a soft difficulty manager, letting you abandon a puzzle that needs a tool you haven't found yet and circle back later with new understanding. Progress comes in two distinct waves. First, you learn to read impossible spaces, doors that close when observed, passages that lead to different places depending on which direction you enter them, dead ends that dissolve once you stop treating them as dead ends. Then the blue Matter Gun arrives, and the second wave begins. You collect upgrades through four colour tiers, blue through red, each one granting new ways to pick up, place, grow, and replicate the small coloured cubes scattered throughout the world. Blocking laser beams, building makeshift bridges, triggering chains of doors across the map, the cube manipulation quietly becomes its own puzzle language running in parallel with the spatial one. The soundscape deserves a paragraph on its own. Ambient chimes, water sounds, and sparse tones give the white-walled corridors the mood of a monastery set aside for contemplation, which is exactly the mental posture the puzzles ask of you. There is no antagonist, no dialogue, no narrative scaffolding of any kind. The closest thing to a story is the wall-mounted aphorisms that appear beside each puzzle, short, fortune-cookie observations about perception and assumption that somehow land harder in context than they would anywhere else. Some people will find that emptiness liberating. Others will find it lonely. Both reactions are valid. The honest criticisms are real. Replayability is close to zero once the puzzles are solved. A handful of late-game cube manipulation challenges tip from demanding into obtuse, particularly when the game withholds enough information about each gun's subtler behaviour that you genuinely cannot tell whether you are missing a technique or just missing a better gun. Some reviewers found that the second half, once the Matter Guns dominate, loses some of the pure spatial sorcery that makes the opening hours feel so alive. There is also no story payoff at the end, the resolution is abstract and brief, which fits the design philosophy but will frustrate anyone expecting closure. For a certain kind of player, the one who loved the silent rule-discovery of The Witness, who finds Portal's hand-holding slightly too generous, who wants a puzzle game that treats them like a scientist rather than a student, Antichamber is close to irreplaceable. It is a one-person achievement built over several years, and it still feels like nothing else released before or since. Go in without a walkthrough, accept that confusion is the curriculum, and give it at least three hours before you judge it. Kai, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
